Authentication
api key header
The Pika API uses API keys to authenticate requests. Send your key in the X-API-Key header. 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.

media inputs
Media inputs accept any public URL. To use a local file, POST its content_type and size_bytes to /v1/media/uploads, PUT the file to the returned upload_url, then pass the url.

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.
| Status | When | Body |
|---|---|---|
| 401 Unauthorized | The API key is missing or invalid. | {"message":"Invalid API key"} |
| 403 Forbidden | The key is not active, or the org balance cannot cover the request. | {"message":"Insufficient org balance"} |
| 404 Not Found | No job with that id exists in your org. | {"message":"media job not found"} |
| 409 Conflict | The 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 Entity | The 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 Requests | Org limit reached: requests per minute or day, or concurrent jobs. Check the Retry-After header. | {"message":"rate limit exceeded: rpm"} |
| 503 Service Unavailable | The model rail or a backend dependency is temporarily unavailable. Retry with backoff. | {"message":"media dispatch unavailable"} |
