HTTP status: 401

Message

Authorization header is malformed or the key prefix doesn’t match any active key. Check that you copied the key correctly.

​
Common cause

  • Truncated key (missing characters from a copy-paste).
  • Wrong key format — the value after Bearer must look like 1st_sk_<key_id>.<secret>, with the dot separator intact.
  • Wrong key altogether (paste of a different service’s token).
We deliberately don’t distinguish “wrong key_id” from “wrong secret” in the error — both return this code to avoid leaking which half of the key is correct.

​
Fix

Re-copy the key from the admin panel. The key is only shown ONCE at mint time; if you lost it, mint a fresh one and revoke the lost key.
