How to call it
A starting template for Real Time Finance. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.
# Requires an API key. Check the docs for whether it goes in a header or a query parameter.
curl -s "https://github.com/ENDPOINT" \
-H "Authorization: Bearer YOUR_API_KEY" \
-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.

Real Time Finance — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Real Time Finance free to use?
Real Time Finance 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.
Does Real Time Finance need an API key?
Yes. Real Time Finance 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.
Can I call Real Time Finance from browser JavaScript?
Not directly. Real Time Finance 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 Real Time Finance still working?
Yes, as of 2026-09-18. Our automated check reached Real Time Finance and recorded a 100% reliability score with a median response time of 833 ms. We re-check on a schedule, and this page updates with the result.
Is Real Time Finance available over HTTPS?
No. Real Time Finance 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.
