## OpenAPI

````yaml GET /projects/{id}
openapi: 3.0.3
info:
  title: GC AI External API
  version: 1.0.0
  description: >-
    The GC AI External API allows programmatic access to GC AI's chat
    capabilities. It's designed for integration with workflow automation tools
    like Zapier, Make, n8n, or custom applications.


    ## Authentication


    All API requests must include an API key in the `Authorization` header:


    ```

    Authorization: gcai_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

    ```


    API keys can be created in the GC AI app under **Settings → API**.


    ## Current Limitations


    The API is optimized for single-turn completions. The following are not yet
    available via API:


    - **Multi-turn conversations**: each request is independent

    - **Interactive clarification**: the model cannot pause to ask the caller a
    follow-up question; the `askUserQuestions` tool is disabled on the API
    surface in beta


    ## Usage


    Usage is tracked and viewable in the GC AI app under **Settings → API → View
    Usage**.


    ## Support
