Resolve allowlisted scoped external identities
Exact namespace lookup only. ATP player codes can be scoped by discipline; archive-match keys require season and discipline, with optional event. Ambiguity returns HTTP 409 and up to six candidate own IDs, never a guessed merge. The prepared lookup is immutable per release. No source payload, private path or alias enumeration is returned.
Authentication
Private development credential: keyId.secret; rotate/revoke through the offline operations CLI.
Headers
Optional client logical-operation identifier. Scoped to principal, channel and operation class. A different canonical request conflicts; expired replay returns 410. RapidAPI retries without this stable identifier are separate attempts/operations.
Request
Response headers
Durable logical operation UUID; shared by keyed retries. Not a credential.
