Run an endpoint against the live API with your own key. Nothing is proxied — the request goes straight from your browser to the API, and your key never leaves this page.

Live calls need this site’s origin on the API’s CORS allow-list. If a request fails with a network/CORS error, use Copy as cURL below and run it from your terminal — that always works. See rate limits for throttling.
