Sec-Token-Binding

IANA permanent RFC 8473

Registered with IANA and declared by no provider in the APIs.io network.

A count here is providers whose published contract declares this header — not providers who send it. Response headers set at the edge rarely appear in an OpenAPI at all, so a low number can measure documentation practice rather than deployment.
