​
Overview

The Voice API provides a complete telephony platform for placing outbound calls with custom caller ID, CNAM branding, call recording, and compliance management. Base URL: https://api.revdesk.com/v1
Building in TypeScript? Skip the raw HTTP and use the official @revdesk/sdk (typed REST client) and @revdesk/webrtc (browser calling). See Official SDKs.

​
Rate limits

All endpoints are rate limited to 600 requests per minute per API key (120/min for demo keys). Rate-limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset) are returned on each response. The request rate is separate from how many calls can run at once. Concurrent capacity is set by your account’s provisioned call capacity. Need more? Contact us to raise it.
