How to call it

A starting template for 18F. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.

# No authentication required.
curl -s "http://18f.github.io/ENDPOINT" \
  -H "Accept: application/json"

This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

This API is served over plain HTTP. Browsers block HTTP requests made from an HTTPS page, so you will need a server-side call.

Where this listing comes from

Aggregated from one public source (public-apis), then normalised and checked by us. If something here is wrong, tell us and we will correct it.

18F — common questions

Answered from what our own scheduled checks found, not from the provider's marketing.

Is 18F free to use?

18F is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.

Does 18F need an API key?

No. We called 18F on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.

Can I call 18F from browser JavaScript?

Not directly. 18F did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.

Is 18F still working?

Not at our last check on 2026-09-18. 18F did not respond successfully, which is why it is marked as down here. This may be temporary; we re-check on a schedule and the badge above reflects the most recent run.

Is 18F available over HTTPS?

No. 18F 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.
