This API cannot access desktop telemetry, personal data, accounts, settings, or PC controls. Send only public topic words. Unknown and duplicate query parameters are rejected. All API requests, including HEAD, invalid, and unsupported requests, use one token from a shared per-client fixed window of 120 requests per 60 seconds for each runtime instance. See https://feex.it/developers/api-policy/ for versioning, deprecation, and rate-limit semantics. The Feex Wiki also provides negotiated Markdown at its HTML routes and a developer guide at https://feex.it/wiki/developers/. API availability depends on the Feex hosting adapter; the Astro static preview alone does not run search or article endpoints.",
