# List all available task executors

> List all available task executors for workflow composition.

**Overview**
Task executors are reusable building blocks for workflows. Each executor performs
a specific operation (send email, extract data, classify documents, etc.). This
endpoint provides discovery of all registered executors with their schemas,
enabling programmatic flow builder UIs and validation.

**What are Task Executors?**
Task executors are typed workflow components that:
- Accept configuration parameters (e.g., API keys, endpoints, templates)
- Optionally receive runtime input data (for input executors)
- Perform an operation (API call, data transformation, ML inference)
- Return structured output for downstream tasks
- Support scheduling (for compatible executors)

**Executor Categories**
1. Input Executors (is_input_task_executor=true):
   - Trigger flows from external sources
   - Examples: receive_email, webhook_receive, receive_file
   - Have flow_input_schema defining incoming data

2. Processing Executors (is_input_task_executor=false):
   - Transform data within flows
   - Examples: doc_to_structured, classify_text, format_data
   - No flow_input_schema (work on task outputs)

3. Output Executors:
   - Send data to external systems
   - Examples: send_email, webhook_notification, external_db
   - Can be terminal tasks in flows

4. Schedulable Executors (is_schedulable_executor=true):
   - Support time-based triggers
   - Examples: scheduled_db_query
   - Can run on cron schedules

**Response Format**
Returns array of TaskExecutorResponse objects containing:
- Executor metadata (name, description, agent prompt)
- Configuration schema (parameters_schema) - JSON Schema for static config
- Runtime input schema (flow_input_schema) - JSON Schema for dynamic data
- Capability flags (is_input_task_executor, is_schedulable_executor)

**Schema Usage**
- parameters_schema: Generate configuration UI, validate flow definitions
- flow_input_schema: Validate incoming webhook/email/file data
- Both schemas follow JSON Schema Draft 2020-12 specification

**Use Cases**
- Flow Builder UI: Display available task types with autocomplete
- AI Agents: Use agent_prompt to intelligently select executors
- Validation: Check flow definitions against executor schemas
- Documentation: Generate API reference from executor metadata
- Client SDKs: Generate type-safe executor configuration classes

**Executor Registration**
Task executors are registered via TaskExecutorsManager (flow-sdk).
To add custom executors, see flow-sdk/src/flow_sdk/task_executors/README.md

**Performance Notes**
- Response cached for 5 minutes (executors rarely change)
- Typical response size: ~50-100 executors, 200-500KB
- Schemas can be large (1-10KB per executor)
- Consider client-side caching for production use

**Related Endpoints**
- POST /flows - Create flow using discovered executors
- GET /flows/{id} - View flow definition with executor references
- POST /task-data - Get task output schemas for flow validation

      Flow management operations for defining and organizing workflows.


      Flows represent workflow definitions with tasks, dependencies, and
      execution logic. They serve as reusable templates that can be executed
      multiple times with different inputs.


      **What is a flow?**

      A flow consists of:

      - **Tasks**: Individual units of work that perform specific actions

      - **Dependencies**: Relationships between tasks that define execution
      order

      - **Configuration**: Settings and parameters that control flow behavior


      **Use these endpoints to:**

      - Create new flow definitions from scratch or import from YAML

      - List and search existing flows in your organization

      - Retrieve detailed flow information including task definitions

      - Update flow configurations and task parameters

      - Delete flows that are no longer needed


      Flows are the foundation of your workflow automation—once defined, they
      can be executed via the flow-executions endpoints.
    name: flows
    x-displayName: Flows
  - description: >-
      Flow execution operations for running and monitoring workflows.


      Flow executions represent runtime instances of flows. When you execute a
      flow, a new flow execution is created with its own unique ID, status, and
      execution context. Each execution is independent and maintains its own
      state, input data, and results.


      **Key concepts:**

      - **Execution Status**: Tracks the lifecycle (running, completed, failed,
      cancelled)

      - **Run Number**: Sequential identifier for executions of the same flow

      - **Execution Context**: Contains input parameters, user information, and
      metadata

      - **Task Results**: Stores outputs from each task within the execution


      **Use these endpoints to:**

      - Start new flow executions with custom input parameters

      - Monitor execution progress and status in real-time

      - Retrieve execution history and detailed results

      - Filter and search executions by status, date, or flow

      - Cancel running executions when needed

      - Access task-level execution details and outputs


      Flow executions transform flow definitions into actual work and
      deliverable results.

  - description: >-
      Task execution operations for tracking individual task runs within flow
      executions.


      Task executions represent individual task runs within a flow execution.
      Each task in a flow execution has its own task execution record that
      tracks its lifecycle, inputs, outputs, and status.


      **What is tracked:**

      - **Status**: Current state (pending, running, completed, failed, skipped)

      - **Input/Output**: Data passed to and produced by the task

      - **Timing**: Start time, end time, and duration

      - **Errors**: Failure details and error messages

      - **Tags**: Metadata and categorization


      **Use these endpoints to:**

      - Query task execution status for debugging

      - Retrieve task outputs for analysis

      - Debug task failures with detailed error information

      - Track task performance and timing

      - Monitor task execution progress within flows


      Task executions provide granular visibility into workflow execution,
      essential for debugging and optimization.

      Task executor operations for discovering available task types and their
      capabilities.


      Task executors define the available task types that can be used in flow
      definitions. Each executor specifies its input schema, execution behavior,
      and capabilities. This endpoint enables programmatic discovery of task
      types for building flows dynamically.


      **What task executors provide:**

      - **Input Schema**: JSON Schema defining required and optional parameters

      - **Output Schema**: Expected output structure and data types

      - **Description**: Human-readable explanation of functionality

      - **Agent Prompts**: Instructions for AI-powered flow generation


      **Use these endpoints to:**

      - Discover available task types for flow building

      - View task input/output schemas for validation

      - Understand task capabilities and requirements

      - Build flow builder UIs with dynamic task lists

      - Enable AI agents to select appropriate tasks


      Task executors enable dynamic, flexible workflow creation by providing a
      registry of available operations.
    name: task-executors
    x-displayName: Task Executors
  - description: >-
      Task output operations for storing and retrieving task execution results.


      Task outputs store the results produced by task executions in a
      structured, queryable format. While task executions track the full
      lifecycle (input, output, error, status), task outputs focus specifically
      on the final output data formatted for display, analysis, and downstream
      consumption.


      **Key characteristics:**

      - **Summary Field**: Structured output data ready for consumption

      - **Historical Record**: Permanent storage of task results

      - **Queryable**: Filter and search outputs by task, execution, or flow

      - **Linked**: Connected to parent flow execution and task execution


      **Use these endpoints to:**

      - Store task results after successful execution

      - Retrieve outputs for specific tasks or entire executions

      - Query historical outputs for analysis and reporting

      - Access formatted results for display in dashboards

      - Feed outputs to downstream tasks or external systems


      Task outputs provide the data foundation for workflow analytics,
      debugging, and result visualization.
    name: task-outputs
    x-displayName: Task Outputs
  - description: >-
      Task data operations for flow validation, schema discovery, and dynamic
      configuration.


      The task-data endpoint analyzes flow definitions to extract task output
      schemas, dynamic configuration options, and validation errors. This is
      essential for building flow configuration UIs, validating flows before
      execution, and understanding task data structures.


      **Primary Use Cases:**

      - **Flow Builder UI**: Get task output schemas for validating downstream
      task inputs

      - **Schema Discovery**: Understand the structure of data each task
      produces

      - **Dynamic Configuration**: Retrieve runtime-dependent options (e.g.,
      available spreadsheets, database tables)

      - **Flow Validation**: Validate flow definitions programmatically before
      saving or executing

      - **Custom Integrations**: Build tools that work with SuperAI Flows
      programmatically


      **What You Get:**

      - **Output Schemas**: JSON Schema definitions for each task's output
      structure

      - **Dynamic Data**: Runtime-dependent configuration options (dropdown
      choices, conditional fields)

      - **Validation Errors**: Detailed error messages for invalid flow
      definitions


      **How It Works:**

      1. Submit a flow definition in SuperAI Flows DSL format

      2. The endpoint validates the structure and loads each task executor

      3. For each task, it extracts the output schema and any dynamic
      configuration data

      4. Returns all schemas, dynamic data, and any validation errors
      encountered


      **Key Concepts:**

      - **Output Schema**: JSON Schema describing the structure of data a task
      produces

      - **Dynamic Data**: Configuration options that depend on user credentials
      or external state (e.g., list of Google Sheets accessible with your
      credentials)

      - **Validation Levels**: Basic (structure only) vs Full (includes semantic
      validation)


      **Integration Notes:**

      - The flow builder frontend uses this endpoint to power the task
      configuration UI

      - Flows API uses this validation internally when creating/updating flows

      - Response includes validation errors even on HTTP 200 - always check
      `validation_errors` field

      - May make external API calls to fetch dynamic data, so response time
      varies (100ms-2s typical)


      **Related Endpoints:**

      - `GET /task-executors`: List available task executor types and their
      schemas

      - `POST /flows`: Create flow (uses task-data validation internally)

      - `PUT /flows/{flow_id}`: Update flow (uses task-data validation
      internally)

      Task tag operations for categorizing and organizing tasks with metadata.


      Task tags provide metadata and categorization for tasks within flow
      executions. Tags enable flexible organization, filtering, and grouping of
      tasks beyond their structural relationships.


      **What tags enable:**

      - **Categorization**: Group related tasks across different flows

      - **Filtering**: Query executions by tag criteria

      - **Metadata**: Attach custom key-value pairs to tasks

      - **Organization**: Create logical groupings for reporting


      **Use these endpoints to:**

      - Manage task labels and categories

      - Add organizational metadata to tasks

      - Query tasks by tag criteria

      - Build custom views and dashboards


      Task tags provide flexible organization capabilities that enhance workflow
      management and analysis.

      Authentication operations for user authentication, authorization, and
      session management.


      Authentication endpoints handle user identity verification, token
      generation, and access control throughout the platform. The system uses
      JWT (JSON Web Token) based authentication managed through
      core.flows.super.ai.


      **Authentication flow:**

      1. Obtain credentials from your account at core.flows.super.ai

      2. Authenticate to receive JWT access token and refresh token

      3. Include access token in API requests via Authorization header

      4. API validates tokens and extracts user identity and organization
      context

      5. Tokens expire after 1 hour and must be refreshed


      **Key concepts:**

      - **Bearer Tokens**: Short-lived JWT tokens (1 hour) used for API requests

      - **Anon-Key**: Long-lived API key used to authenticate to the
      authentication API.

      - **Refresh Tokens**: Long-lived tokens used to obtain new access tokens

      - **Protected Routes**: Most endpoints require valid authentication

      - **Public Endpoints**: Limited whitelisted paths accessible without auth


      **Getting started with authentication:**


      1. **Obtain your Anonymous Key** (public endpoint - no authentication
      required):
         ```bash
         curl https://flows.super.ai/api/auth/anon-key
         ```

      2. **Authenticate** to receive your tokens:
         ```bash
         curl -X POST 'https://core.flows.super.ai/auth/v1/token?grant_type=password' \
           -H 'Content-Type: application/json' \
           -H 'apikey: ANON_KEY' \
           -d '{"email": "you@example.com", "password": "your-password"}'
         ```
         This will return a JWT access token and refresh token.

      3. **Use the access token** in your requests:
         ```bash
         curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
              https://flows.super.ai/api/flows
         ```

      **Token management:**

      - Access tokens expire after 1 hour

      - Use refresh tokens to obtain new access tokens without re-authenticating

      - Store tokens securely and never commit them to version control


      All API endpoints (except whitelisted public paths) require
      authentication. Include your bearer token in the Authorization header:
      `Bearer <token>`

    x-displayName: Authentication
  - description: >-
      User profile operations for viewing and updating account information.


      Profile endpoints allow authenticated users to view and update their own
      account information and preferences. These endpoints operate on the
      currently authenticated user (determined from the JWT token) and do not
      require specifying a user ID.


      **Account information includes:**

      - **Personal Details**: First name, last name, email

      - **Organization**: Associated organization and role

      - **Status**: Account status and permissions

      - **Metadata**: Created/updated timestamps


      **Use these endpoints to:**

      - Retrieve current user information for display

      - Update personal details (name, preferences)

      - View organization membership and role

      - Access account metadata


      Profile endpoints provide self-service account management capabilities,
      reducing the need for administrative intervention for routine updates.


      **Note:** All profile endpoints are protected and automatically scope to
      the authenticated user. Email and organization changes require admin
      privileges.

      Model operations for querying available AI models and their
      configurations.


      Model endpoints provide information about the AI models available through
      the platform. These endpoints enable discovery of models, their
      capabilities, and regional availability.


      **Key features:**

      - **Model Discovery**: List all available AI models

      - **Regional Filtering**: Query models by geographic region (EU, Global)

      - **Model Metadata**: Access model information including provider,
      location, and capabilities


      **Use these endpoints to:**

      - Discover available AI models for your workflows

      - Filter models by region for compliance or latency requirements

      - Retrieve model metadata for configuration and selection

      - Build dynamic model selection UIs


      **Regional filtering:**

      - `eu`: Models deployed in European regions (West Europe, France Central,
      Germany, Sweden)

      - `global`: Models deployed in US and other global regions


      Model endpoints enable intelligent model selection and routing based on
      your requirements for compliance, performance, and cost.

      File download operations for retrieving files from gs:// storage URIs.


      When Super.AI Flows processes documents, task outputs often include file
      references as `gs://` URIs pointing to Google Cloud Storage. These
      endpoints let you download those files without needing to understand GCS
      internals or parse storage URLs.


      **The problem these endpoints solve:**


      Previously, downloading a file required:

      1. Recognizing the URL as a GCS reference

      2. Parsing out the file key from the URI

      3. Calling a separate endpoint to get a signed URL

      4. Downloading using that signed URL


      **Now it's simple:** Pass the `gs://` URI exactly as received and get your
      file.


      **Two ways to download:**


      1. **Direct download** (`GET /files/download`): Returns a redirect to the
      file. Perfect for curl with `-L` flag.
         ```
         curl -L -H "X-API-Key: saf_xxx" "https://flows.super.ai/api/files/download?uri=gs://..." -o file.pdf
         ```

      2. **Resolve first** (`POST /files/resolve`): Returns a JSON response with
      the download URL. Better for programmatic use and sensitive files (keeps
      URI out of logs).
         ```
         curl -X POST "https://flows.super.ai/api/files/resolve" \
           -H "X-API-Key: saf_xxx" \
           -H "Content-Type: application/json" \
           -d '{"uri": "gs://..."}'
         ```

      **Security:**

      - Files are organization-scoped: you can only download files from flows
      your organization owns

      - URIs are validated to prevent path traversal attacks

      - Download URLs expire after 1 hour


      **Common use cases:**

      - Download processed documents from completed flow executions

      - Retrieve extracted data files from task outputs

      - Integrate file downloads into automated pipelines

        List all available task executors for workflow composition.


        **Overview**

        Task executors are reusable building blocks for workflows. Each executor
        performs

        a specific operation (send email, extract data, classify documents,
        etc.). This

        endpoint provides discovery of all registered executors with their
        schemas,

        enabling programmatic flow builder UIs and validation.


        **What are Task Executors?**

        Task executors are typed workflow components that:

        - Accept configuration parameters (e.g., API keys, endpoints, templates)

        - Optionally receive runtime input data (for input executors)

        - Perform an operation (API call, data transformation, ML inference)

        - Return structured output for downstream tasks

        - Support scheduling (for compatible executors)


        **Executor Categories**

        1. Input Executors (is_input_task_executor=true):
           - Trigger flows from external sources
           - Examples: receive_email, webhook_receive, receive_file
           - Have flow_input_schema defining incoming data

        2. Processing Executors (is_input_task_executor=false):
           - Transform data within flows
           - Examples: doc_to_structured, classify_text, format_data
           - No flow_input_schema (work on task outputs)

        3. Output Executors:
           - Send data to external systems
           - Examples: send_email, webhook_notification, external_db
           - Can be terminal tasks in flows

        4. Schedulable Executors (is_schedulable_executor=true):
           - Support time-based triggers
           - Examples: scheduled_db_query
           - Can run on cron schedules

        **Response Format**

        Returns array of TaskExecutorResponse objects containing:

        - Executor metadata (name, description, agent prompt)

        - Configuration schema (parameters_schema) - JSON Schema for static
        config

        - Runtime input schema (flow_input_schema) - JSON Schema for dynamic
        data

        - Capability flags (is_input_task_executor, is_schedulable_executor)


        **Schema Usage**

        - parameters_schema: Generate configuration UI, validate flow
        definitions

        - flow_input_schema: Validate incoming webhook/email/file data

        - Both schemas follow JSON Schema Draft 2020-12 specification


        **Use Cases**

        - Flow Builder UI: Display available task types with autocomplete

        - AI Agents: Use agent_prompt to intelligently select executors

        - Validation: Check flow definitions against executor schemas

        - Documentation: Generate API reference from executor metadata

        - Client SDKs: Generate type-safe executor configuration classes


        **Executor Registration**

        Task executors are registered via TaskExecutorsManager (flow-sdk).

        To add custom executors, see
        flow-sdk/src/flow_sdk/task_executors/README.md


        **Performance Notes**

        - Response cached for 5 minutes (executors rarely change)

        - Typical response size: ~50-100 executors, 200-500KB

        - Schemas can be large (1-10KB per executor)

        - Consider client-side caching for production use

        Response model for a task executor definition.


        Task executors are reusable workflow components that perform specific
        operations

        within a flow. Each executor defines its input schema, execution
        behavior, and

        capabilities. This model provides all metadata needed to
        programmatically

        discover and configure task executors in flow definitions.
      example:
        is_input_task_executor: false
        is_schedulable_executor: false
        parameters_schema:
          properties:
            model:
              default: gpt-4-vision

            Only present for executors that can trigger/receive flow executions
            (is_input_task_executor=true). 


            Defines the shape of data received from external sources: webhooks,
            email attachments, file uploads, scheduled triggers, etc. 


            Difference from parameters_schema:

            - parameters_schema: Static configuration set during flow design

            - flow_input_schema: Dynamic data received at runtime


            Example: An 'receive_email' executor has:

            - parameters_schema: {email_address, filters, ...} (configuration)

            - flow_input_schema: {from, subject, body, attachments, ...}
            (runtime data)


            Null for non-input executors (standard task executors).
          examples:
            - properties:
                attachments:
                  description: File URLs for attachments
                  items:

        is_input_task_executor:
          description: >-
            Whether this executor can trigger flow execution from external
            sources. 


            Input executors (true):

            - Receive data from external systems (webhooks, emails, files,
            schedules)

            - Can be first task in a flow

            - Have flow_input_schema defining received data structure

            - Examples: receive_email, receive_file, webhook_receive


            Non-input executors (false):

            - Process data within flow execution

            - Cannot trigger flows (must be downstream of input executor)

            - No flow_input_schema

            - Examples: send_email, doc_to_structured, classify_text,
            external_db


            Used by flow validators to ensure flows have at least one input
            executor.
          examples:
            - true
            - false
          title: Is Input Task Executor

        is_schedulable_executor:
          description: >-
            Whether this executor supports scheduled/recurring execution. 


            Schedulable executors (true):

            - Can run on cron schedules (hourly, daily, weekly, custom)

            - Support time-based triggers

            - Often paired with input executors

            - Examples: scheduled_db_query


            Non-schedulable executors (false):

            - Event-driven only (triggered by upstream tasks or external events)

            - Cannot run on schedule

            - Examples: send_email, classify_document, receive_email
            (event-driven)


            Note: Scheduling is configured at the flow execution level, not per
            task. This flag indicates executor compatibility with scheduling.
          examples:
            - true
            - false
