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.

Reference Uploads

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.

upload
# 1. Request a presigned upload URL. Send the file's content
#    type and its exact size in bytes.
curl -X POST https://api.dev.pika.art/v1/media/uploads \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"content_type": "image/png", "size_bytes": 12345}'


# The response returns two URLs:
#   upload_url: a temporary URL to upload the file to. Expires in 5 minutes.
#   url:        the permanent Pika URL. Pass it to the model as the input.

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.

StatusWhenBody
401 UnauthorizedThe API key is missing or invalid.{"message":"Invalid API key"}
403 ForbiddenAn 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 FoundNo job with that id exists in your org, or the media path names an unknown vendor/model/function.{"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. 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 RequestsOrg 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 UnavailableThe 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"}}
