**Semasio publishes no public API.** There is no developer portal, no API reference, no SDK,
no webhook catalog and no machine-readable specification (OpenAPI, AsyncAPI, GraphQL SDL,
Postman collection or JSON Schema) on any Semasio host. An agent cannot integrate with
Semasio programmatically from public information; access runs through a sales conversation
and the login-only Semasio platform.
