Clipkit Render API
Plain-HTTPS render API documented in the Vercel integration guide. POST a CKP/1.0 Source JSON to /api/v1/renders with Authorization Bearer CLIPKIT_API_KEY, then poll GET /api/v1/renders/{id} for status and a signed output_url to the finished MP4; webhooks deliver render.completed / render.failed. No OpenAPI is published; the contract here is generated from the documentation by API Evangelist (2026-11-04), not the provider's own document.
