Zeffy Rate Limits

Zeffy's public API enforces a documented rate limit of 100 requests per minute per API key. Exceeding the limit returns HTTP 429. Connections are HTTPS-only. The API is read-only and free, so there is no separate paid quota tier - the same 100 requests/minute limit applies to every organization's API key.
