Who else is in the request path
Cloudflare, Inc. Requests to this endpoint pass through Cloudflare (Cloudflare, Inc., US), which terminates TLS in front of the API. That means Cloudflare, Inc. decrypts the request and can see the Authorization header carrying your key. This is normal infrastructure practice, not a defect, but it is a party in the path that the provider's own documentation does not mention.
