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.
X-API-Key: YOUR_API_KEY
Endpoint
asynchronous · poll for the result
REST Setup
plain HTTPS
Audio generation runs through the REST endpoint shown above. The API is plain JSON over HTTPS, so any HTTP client works. No provider-specific SDK is required.

Returns
Returns a job object with status , not the final output. Store the id from the response and poll the job until it completes.

Errors
shared across calls
Errors use conventional HTTP status codes with a JSON body of the shape {"message": "..."}. Validation failures return 422 with a message naming the offending field. Submit rejections after the job row exists (balance, rate limit) return the failed job envelope — branch on error.code.
| Status | When | Body |
|---|---|---|
| 401 Unauthorized | The API key is missing or invalid. | {"message":"Invalid API key"} |
| 403 Forbidden | An inactive key is rejected with a `{"message"}` body. A submit that the org balance or postpaid cycle limit cannot cover is rejected after the job row exists and returns the failed job envelope. | {"id":"media_8f3a2c91-5b7d-4e0a-9c26-31d4f2a8e6b0","status":"failed","error":{"code":"insufficient_balance","message":"Insufficient org balance"}} |
| 404 Not Found | No job with that id exists in your org, or the media path names an unknown vendor/model/function. | {"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. The JSON message names the offending field. A schema-valid parameter combination that cannot be priced instead fails after job creation and returns the failed job envelope with error code `invalid_input`. | {"message":"duration: Input should be less than or equal to 15"} |
| 429 Too Many Requests | Org limit reached: requests per minute or day, or concurrent jobs. Returned as the failed job envelope; check the Retry-After header and retry with a fresh Idempotency-Key. | {"id":"media_8f3a2c91-5b7d-4e0a-9c26-31d4f2a8e6b0","status":"failed","error":{"code":"rate_limited","message":"rate limit exceeded: rpm"}} |
| 503 Service Unavailable | The model rail or a backend dependency is temporarily unavailable. Returned as the failed job envelope; retry with backoff and a fresh Idempotency-Key. | {"id":"media_8f3a2c91-5b7d-4e0a-9c26-31d4f2a8e6b0","status":"failed","error":{"code":"provider_unavailable","message":"media dispatch unavailable"}} |
