Answered from what our own scheduled checks found, not from the provider's marketing.
Charity Search is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Yes. Charity Search authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.
Yes. Charity Search returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.
Yes, as of 2026-09-18. Our automated check reached Charity Search and recorded a 100% reliability score with a median response time of 965 ms. We re-check on a schedule, and this page updates with the result.
No. Charity Search was only reachable over plain HTTP when we checked. Browsers block HTTP requests made from an HTTPS page, so this will fail in production unless you call it from a server instead.
