Interns

Create an intern

Creates an intern in an explicit workspace. The operation also creates its private vault. It can start provisioning immediately or wait for a later provision call. A retry with the same idempotency key and body resumes unfinished work. The request body is capped at 1048576 bytes and a larger body is refused with 413. A non-empty body must declare Content-Type: application/json or it is refused with 415. The API key selects the caller, workspace and visible interns. There is no default workspace fallback. Requests on regional hostnames such as eu.openrouter.ai are refused. API key required.

post/interns

Headers

Idempotency-Keystring
