The corporate search service behind knightfrank.com and knightfrank.co.uk, titled "KnightFrank Api v3" by its own OpenAPI document. It exposes 11 operations across seven tags — CMSPage, IntelligenceLab, Office, Person, Search, ServiceLine and Telemetry — covering CMS content search, the Knight Frank Intelligence Lab research index, the global office directory, the people/partner directory with autocomplete, a general cross-site search, service-line lookup and a selection-count telemetry write. It is NOT a published developer product: Knight Frank advertises it nowhere, documents it nowhere, and offers no terms, keys or signup for it. It is recorded here because it is a genuine, verifiable machine-readable contract that is reachable anonymously. Probed on 2026-07-26, the Swagger UI at /swagger/index.html returned HTTP 200, /swagger/v1/swagger.json returned HTTP 200 with a valid OpenAPI 3.0.1 document, and GET /office and GET /person returned HTTP 200 with real office and staff records to a client presenting no credential of any kind. There is no securitySchemes block in the document and no authentication is enforced.
