Every service definition, layer definition and /query call in arcgis/ and examples/ was made anonymously and returned 200. The ArcGIS Server behind them does advertise token-based security for privileged operations, so the token service is recorded here as the escalation path, not as a requirement for public reads. schemes: - id: anonymous type: none applies_to: - GET /arcgis/rest/services - GET /arcgis/rest/services/FCA - GET /arcgis/rest/services/FCA/{service}/MapServer - GET /arcgis/rest/services/FCA/{service}/MapServer/{layerId} - GET /arcgis/rest/services/FCA/{service}/MapServer/{layerId}/query verified: probed evidence: >- https://wgis.fca.gov/arcgis/rest/services/FCA/hq/MapServer/0/query?where=1=1&returnCountOnly=true&f=json returned {"count":55} with no Authorization header and no token parameter. - id: arcgis-token type: token style: query parameter or header (Esri ArcGIS Server token) token_service: https://wgis.fca.gov/arcgis/tokens/ short_lived_token_validity_minutes: 60 required_for_public_read: false scope_note: >- Reported by the server itself in /arcgis/rest/info as authInfo.isTokenBasedSecurity=true, tokenServicesUrl=https://wgis.fca.gov/arcgis/tokens/, shortLivedTokenValidity=60. This governs administrative and secured services; the three FCA folder services are open. oauth2: false openid_connect: false mutual_tls: false api_keys: false docs: null docs_note: >- FCA publishes no authentication documentation of any kind for this surface, because it publishes no developer documentation of any kind for it. The auth model above was established by probing, not by reading. The generic protocol reference is Esri's (ArcGIS REST API), not FCA's. gaps: - No developer portal, API reference, or getting-started page names these endpoints. - No /.well-known/oauth-authorization-server or openid-configuration on any FCA host. - No rate-limit, quota or terms-of-use statement attached to the anonymous read surface.
