4. Before you ship

Set a timeout and handle non-200 responses: free APIs can rate-limit or go down.
Cache responses where you can, instead of calling the API on every page view.
Read the official documentation ↗ for rate limits and terms of use.

FAQ

Does the Wheelwise API need an API key in C#?

No. The Wheelwise API works without an API key, so the C# example runs as-is.

Can I call the Wheelwise API from the browser?

Not reliably: it doesn't send CORS headers. Call it from a server, serverless function or script.

What does the Wheelwise API return?

JSON. The example response on this page is trimmed from a real response our health check received on Oct 24, 2026.
