APIX Services Profile: Discovery Infrastructure for Web API and Bot Services

This document defines the APIX Services Profile: an extension to the APIX Core Infrastructure specification that enables discovery and automated verification of web API and bot-consumable services. It specifies the APM field set for API services, the APIX Spider verification protocol, liveness monitoring configuration, search and filter query semantics, and the service record schemas (Level 1 summary and Level 2 full record) returned to consuming agents. Autonomous agents that implement this profile can discover API services globally from a single entry point, evaluate their trust posture without any out-of-band knowledge, and select services that satisfy their own Trust Policy.
