1. Get an API key
Subscribe to a plan at Polar.sh to receive your API key. Keys use the formatBOROUGH_<uuid>.
Free-tier search endpoints work without authentication (IP-based rate limiting applies).
2. Make your first request
3. Understand the response
Every response follows this envelope:data— The response payload (array for lists, object for single resources)meta.dataAge— When the data was last refreshed (ISO 8601)meta.source— How data was served:cached,stale, orrefreshingmeta.links— Pagination navigation URLs
