AIG Commercial API Gateway
AIG's production API gateway for its commercial broker and producer applications, discovered from the publicly served runtime configuration of the AIG Producer Management Portal. The host is live and answers on real routes (/pmp-gateway/c2a/pmp-ext-gtw-api and /pmp-usrmgmt-gateway/c2a/pmp-ext-usermgmt-gtw-api) but every anonymous call is rejected by an Okta-backed "Protect Proxy" policy. AIG publishes no contract, reference, or documentation for it; the auth model, scopes and error envelopes recorded here were established by probing the gateway and by reading AIG's own anonymously-served OAuth/OIDC discovery documents.
