Authorization: Bearer <SCRINLY_API_KEY>. The endpoint pages in this reference are generated from the public OpenAPI 3.1 contract and can be tried from the API playground.
Screenshots return image/png or image/jpeg bytes unless storage is enabled. Most other successful calls return JSON. Batch requests can return 207 Multi-Status, and an interpreted blueprint can return a successful blueprint_only partial result.
The legacy api_key query parameter remains available on compatible GET routes, but URLs leak into browser history, access logs, proxies, and analytics. Use the bearer header for all new integrations.
The public contract excludes account provisioning, health probes, statistics, cache administration, and internal operations.
