TESSA Marketing & Technology

TESSA Agent Directory API

FastAPI service behind aiagent.tessa.tech: the A2A agent card and JSON-RPC endpoint, per-service and per-tenant agent cards, the professional-services directory (firm cards and profiles, introduction requests, claim / verify / removal / takedown flows), the TESSA Professional Services A2A extension and service-type taxonomies, and an admin/vector surface. 51 operations, OpenAPI 3.1.0, no securitySchemes declared (admin routes answer 401 on a token the spec does not describe). The same application serves complianceregistry.net and marketingregistry.org; registry-scoped routes return 421 on aiagent.tessa.tech.
