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.

x402 List API — common questions

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

Is x402 List API free to use?

x402 List API is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.

Can I call x402 List API from browser JavaScript?
