Billing
API jobs share the same credit pool as the web editor. 1 credit ≈ one successful edit at or under 1 megapixel; 2 credits if billed output rounds to 2+ megapixels. Rate limit: 30 requests per minute per key. Site-wide daily generation budget also applies when generation is on.
v1 does not include batch zip uploads, webhooks, or team seats. See Docs for Auth, Detect, Edit, and Errors.
