Callab AI API
Callab AI's REST API, documented at docs.callab.ai/api-reference, is organized around REST principles with predictable resource-oriented URLs, standard HTTP verbs, and standard HTTP response codes for programmatic control of voice agents and calls. The public API reference is currently gated behind an access code; the API is served from api.callab.ai. No public OpenAPI specification is published as of this enrichment pass.
