Service-Type Taxonomies
The complete universe of service-type slugs TESSA uses to tag firms in this registry family.
Firm cards expose a subset under _meta['tessa.professional_services.v1'].service_types
— but these endpoints return the full taxonomy so agents can discover slugs even before
any firm has tagged them. JSON endpoints cache for 1 hour.
See also: the
TESSA Professional Services Extension v1
spec for how service_types[] flows from these taxonomies into each firm's A2A card.
