Sec-WebSocket-Accept
IANA permanent
response
RFC 6455
Declared by 1 provider across 1 published specification file 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.
