Developer preview

Two ways into CallVA.

The complete reference is still being assembled. The External API and MCP server below are the live developer surfaces available today.

External API

Operate the platform from code.

Use a bearer token scoped to your organisation or project. The API covers calls, agents, data fields, prompts, schedules and automations.

https://api.callva.one/api/v1/external

POST

/call

GET

/calls

Query calls and outcomes

GET

/calls/aggregate

Aggregate operational metrics

GET

MCP server

Give an AI agent capable hands.

Connect a compatible agent through OAuth 2.1. Each authorization is bound to one organisation and project, without handing the agent a permanent API key.
