Rate limits & fair use

The API is free for personal projects, research, and light app use, but it is heavily rate-limited: 20 requests per minute, per IP. Go over and you'll get an HTTP 429 with a Retry-After header — wait about 60 seconds and retry. Please cache responses where you can, keep the attribution that ships in every payload, and don't re-publish the full dataset wholesale (see our Terms).
