X-Request-Id
Declared by 106 providers across 16781 published specification files in the APIs.io network.
Spelled 3 ways
HTTP field names are case-insensitive (RFC 9110 §5.1), so every spelling below is the same header on the wire. A contract is not the wire: generated clients key off the string, and a developer reading two of these sees two different headers.
