## OpenAPI

````yaml api-reference/openapi.json post /api/v1/youtube/generate-metadata
openapi: 3.1.0
info:
  title: Quiz Quail API
  version: 1.0.0
  description: >-
    The Quiz Quail API lets you create, manage, and render quiz videos
    programmatically. Build quizzes with multiple rounds and question types,
    apply custom themes, render to video, upload to YouTube, and use AI to
    generate quizzes from topics.


    ## Authentication


    All endpoints require a Bearer token (API key). Include it in the
    `Authorization` header:


    ```

    Authorization: Bearer qq_your_api_key_here

    ```


    API keys can be scoped to specific permissions. See the security schemes
    below for available scopes.


    ## Rate Limiting


    Requests are rate-limited per user:

    - **Read** endpoints: 300 requests/minute

    - **Write** endpoints: 30 requests/minute

    - **AI** endpoints: 5 requests/minute

    - **Render** endpoints: 10 requests/hour


    Rate limit headers are included in every response.


    ## Pagination


    List endpoints use cursor-based pagination. Pass the `cursor` from the
    previous response to get the next page. The `hasMore` field indicates
    whether more items exist.


    ## Errors


    Errors follow [RFC 9457 Problem
    Details](https://www.rfc-editor.org/rfc/rfc9457). Every error response
    includes `type`, `title`, `status`, and `detail` fields.
