curl -s "https://cryptolabel.io/ENDPOINT" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -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.

CryptoLabel API — common questions

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

Is CryptoLabel API free to use?

CryptoLabel 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.

Does CryptoLabel API need an API key?

CryptoLabel API requires some form of authentication. Check the provider's documentation for which scheme it expects.

Can I call CryptoLabel API from browser JavaScript?

Not directly. CryptoLabel API 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 CryptoLabel API still working?

Yes, as of 2026-09-18. Our automated check reached CryptoLabel API and recorded a 100% reliability score with a median response time of 1030 ms. We re-check on a schedule, and this page updates with the result.

Is CryptoLabel API available over HTTPS?

Yes. CryptoLabel API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
