Accept-CH
IANA permanent
RFC 8942
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.
