Authentication

api key header

The Pika API uses API keys to authenticate requests. Send your key in the X-API-Keyheader. Your API key is a secret. Don't expose it in browsers or other client-side code. Instead, call the API from your server. The signed-in playground uses a portal session and never sends your API key.

header
X-API-Key: YOUR_API_KEY

Errors

shared across calls

Errors use conventional HTTP status codes with a JSON body of the shape {"message": "..."}. The one exception is validation: a request body that fails validation returns 422 with a plain-text body.

StatusWhenBody
401 UnauthorizedThe API key is missing or invalid.{"message":"Invalid API key"}
403 ForbiddenThe key is not active, or the org balance cannot cover the request.{"message":"Insufficient org balance"}
404 Not FoundNo job with that id exists in your org.{"message":"media job not found"}
409 ConflictThe result was requested before the job completed, or an Idempotency-Key header was reused with a different body.{"message":"media job is not ready"}
422 Unprocessable EntityThe request body failed validation: an invalid enum value, a missing required field, a wrong type, or malformed JSON. Returned as plain text, not JSON. A schema-valid parameter combination that cannot be priced returns the same status with a JSON message.Unprocessable entity
429 Too Many RequestsOrg limit reached: requests per minute or day, or concurrent jobs. Check the Retry-After header.{"message":"rate limit exceeded: rpm"}
503 Service UnavailableThe model rail or a backend dependency is temporarily unavailable. Retry with backoff.{"message":"media dispatch unavailable"}
