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.

  "prompt": "A glamorous dark-skinned Black woman with long voluminous curly burgundy-red hair, tiny white cat-eye sunglasses, glossy dewy makeup and small pastel claw clips in her hair. She wears a lavender-purple sleeveless denim vest and matching low-rise denim, posing with one hand resting delicately near her chin and lips, cool and confident. Set against a hot magenta-pink textured background decorated with lime-green cartoon starbursts, a large glossy chrome 3D metallic star, and scattered white twinkling sparkle stars. Her figure appears as three duplicated cut-out collage layers of the same pose across the frame. Subtle motion: the central figure breathes and tilts her head slightly, curls and fingers moving gently, the chrome star gleaming as light glints and slowly sweeps across it, white sparkle stars twinkling and pulsing. High-saturation Y2K flash-photography aesthetic, glossy skin, grainy printed-poster texture, punchy pink-and-green color grade, playful early-2000s scrapbook collage art direction.",

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"}
