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.

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://089e99349ace.pikalabs.app/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.
# {
#   "upload_url": "https://upload.r2.pika.art/...?X-Amz-Signature=...",
#   "url": "https://cdn.pika.art/v2/media/uploads/org_abc/9f8e7d.png"
# }

# 2. Upload the file to upload_url, then pass url to the model.

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"}
