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.

  "prompt": "A high-fashion editorial film in a vast golden wheat-grass field: a striking model in flowing layered ivory robes and a matching headwrap, a vivid fuchsia silk sash knotted at the waist, stands poised atop a jagged black volcanic rock. Rolling golden hills and hazy blue mountains on the horizon, warm late-afternoon backlight with soft haze. Wind ripples across the grasses and billows the ivory fabric and pink silk in slow waves as she subtly shifts her stance and gazes past the camera with calm confidence. Slow gentle push-in, painterly cinematic grade, soft film grain. Native audio: wind moving through dry grass, faint fabric rustle.",

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"}
