  title: Sphinx Document Fraud API
  version: 1.0.0
  description: >
    Detect forged, tampered, and AI-generated documents. Upload a PDF or image
    and get back a

    structured verdict with a defined set of fraud flags.


    **Quick Start:**

    1. **Create an API key**: sign up, then generate a key from Settings.

    2. **Submit a document**: `POST /api/v1/document-checks/` with a file or a
    URL.
       You get back an id with status `"processing"`.
    3. **Poll for the result**: `GET /api/v1/document-checks/{id}/` until status
    is
       `"completed"` or `"failed"`.

    Optionally pass `webhook_url` on submit to be notified when analysis
    finishes, or

    `?wait=true` to block the submit request for up to 55s.


    **Authentication:** `Authorization: Bearer <api_key>`


    **Decisions:** Every completed check returns a decision (`clear`, `pending`,
    `suspicious`, or

    `fraudulent`), a `risk_level`, a plain-language summary, structured flags,
    and any

    workspace rules that triggered. The four-value decision set is the v1
    contract.
