    Query your project's documentation and API reference content from external
    tools, scripts, or integrations (for example, MCP servers or custom search
    UIs).


    **Path prefix:** If your project is deployed with a path prefix (for
    example, `https://docs.example.com/docs/`), prepend that prefix to the API
    paths (for example, `/docs/_search`).


    {% admonition type="info" %}

    For path prefix configuration, see [custom domain
    configuration](../../reunite/project/custom-domain.md#serve-from-a-subdirectory).

    ## Authentication


    This API uses the same authentication as the project. Public projects (when
    `access.requiresLogin` is not set or is `false`), don't require
    authentication when you call the API. 

    If the project is protected, (`access.requiresLogin: true` or has
    [RBAC](../../access/rbac.md) configuration), you must send the same
    cookie-based session that the browser uses after users logs in. 


    The API does not support API keys or bearer tokens; authentication is
    session (cookie) only. For unauthenticated requests to protected projects,
    both endpoints return empty results instead of errors.

    {% admonition type="info" %}

    To learn more about access and authentication options, see [Access
    control](../../access/index.md).

    {% /admonition %}


    ## CORS and credentials


    When calling from a browser (for example, a custom search UI on another
    origin), the project must allow your origin in CORS. Send credentials
    (cookies) with `fetch(..., { credentials: 'include' })` so that session
    cookies are sent for protected projects.
