USGS Earthquake Hazards Program API not working for you?
- A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
- USGS Earthquake Hazards Program doesn't send CORS headers, so browsers block calls made directly from a web page. Call it from your server instead.
- If it works from one network but not another, check firewalls, VPNs and regional blocks.
- Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.
