A live 200 response carried no X-RateLimit-*, no RateLimit-*, no Retry-After and no quota header of any kind — the only headers returned are x-application-context, content-type, cache-control, HSTS, CSP, x-content-type-options, x-frame-options and server. The docs publish no limit, and the EULA governs licensing rather than request volume. This is an honest zero, not an unchecked field: an agent calling this API has no runtime signal to back off on, which is a real gap for an endpoint that is anonymous and therefore un-attributable. probed: - url: https://fac-api.magvar.com/uncertaintyValues status: 200 rate_limit_headers_present: false observed_headers: [x-application-context, content-type, content-length, date, x-envoy-upstream-service-time, cache-control, content-security-policy, strict-transport-security, x-content-type-options, x-frame-options, server] checked: '2026-09-13' - url: https://fac-api.magvar.com/swagger-ui.html status: 200 note: API reference documents no limits. checked: '2026-09-13' infrastructure_note: >- Responses carry `x-envoy-upstream-service-time`, so the API sits behind an Envoy proxy that could enforce limits without advertising them. Nothing observed suggests a limit was applied during this pass.
