OpenAPI Specification

openapi: 3.2.0
info:
  title: Decart Verify API
  version: 1.0.0
tags:
- name: Verify
paths:
  /v1/verify:
    post:
      summary: Verify Content
      description: 'Check whether a video or image carries the Decart invisible provenance

        watermark. Returns a detection verdict with confidence; the watermark

        survives re-encoding and format conversion.


        AUTHED (API key), like every other /v1 endpoint. A public no-auth tier is

        a conditional follow-up: SB 942 requires a free public detection tool of

        COVERED providers only — if legal rules we''re covered, drop the two auth

        lines below and add per-IP limit_req at external-nginx (both regions)

        before exposure. The hardening here (size cap before body read, in-flight

        cap, sanitized errors) deliberately assumes untrusted callers either way,

        so that flip stays a two-line change.


        Deliberately takes the raw Request, not an UploadFile parameter: FastAPI

        resolves File/Form parameters by spooling the ENTIRE multipart body before

        the handler runs. Auth and Content-Length are checked first; uvicorn/h11

        enforces the declared length, so the cap genuinely bounds spooling.


        Backed by the watermark-verify service (WATERMARK_VERIFY_UPSTREAM); 501

        in environments where none is configured.'
