generated: '2026-08-12' method: probed source: live HTTP probes of every Sinclair-controlled host in apis.yml note: >- sbgi.net serves a real, minimal security.txt (HTTP 200, two directives). Every other /.well-known/ path on sbgi.net returns HTTP 404 with the site's HTML 404 page. The subsidiary hosts were probed as well: dielectric.com, digitalremedy.com and comettv.com return the standard WordPress 404 for all well-known paths, while tennischannel.com and compulse.com are single-page apps that answer HTTP 200 with an HTML shell for EVERY path probed — those 200s are catch-alls, not documents, and are recorded here as misses so a future round does not mistake them for hits. hosts: - host: sbgi.net paths: - path: /.well-known/security.txt url: https://sbgi.net/.well-known/security.txt status: 200 content_type: text/plain document: true file: well-known/sinclair-broadcast-group-security.txt - path: /.well-known/openid-configuration url: https://sbgi.net/.well-known/openid-configuration status: 404 document: false - path: /.well-known/oauth-authorization-server url: https://sbgi.net/.well-known/oauth-authorization-server status: 404 document: false - path: /.well-known/oauth-protected-resource url: https://sbgi.net/.well-known/oauth-protected-resource status: 404 document: false - path: /.well-known/api-catalog url: https://sbgi.net/.well-known/api-catalog status: 404 document: false - path: /.well-known/ai-plugin.json url: https://sbgi.net/.well-known/ai-plugin.json status: 404 document: false - path: /.well-known/agent-card.json url: https://sbgi.net/.well-known/agent-card.json status: 404 document: false - path: /.well-known/agent.json url: https://sbgi.net/.well-known/agent.json status: 404 document: false - path: /llms.txt url: https://sbgi.net/llms.txt status: 404 document: false - path: /openapi.json url: https://sbgi.net/openapi.json status: 404 document: false - path: /graphql url: https://sbgi.net/graphql status: 404 document: false - path: /wp-json/ url: https://sbgi.net/wp-json/ status: 200 content_type: application/json document: true note: >- Not a /.well-known/ path, but this is the machine-readable discovery document this company actually serves — the WordPress REST API route index, 271 routes across 14 namespaces.
