markerapi not working for you?
- A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
- If calls fail only in the browser with a CORS error, markerapi may not allow cross-origin requests. Call it from your server instead.
- markerapi is listed without HTTPS. Browsers block plain-HTTP requests from HTTPS pages (mixed content).
- 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.
