# API reference (OpenAPI)

The Tenant API specification is available in OpenAPI 3.0 format and contains the complete description of every endpoint, request, and response schema. The single specification covers both **KYC** endpoints (sessions, applicants, verification links, etc.) and **KYB** endpoints (`/v1/kyb/businesses`, `/v1/kyb/businesses/{id}`, etc.).
