**APIs profiled:** 21

Zavu is a unified multi-channel messaging platform that consolidates SMS, WhatsApp, Telegram, Email, Voice, and Messenger behind a single REST API, so developers integrate once instead of stitching together Twilio, Vonage, MessageBird and others. The Unified Messaging Layer API adds smart ML-powered channel routing with automatic fallback and retry, signed webhooks for delivery and inbound events, WhatsApp templates and 10DLC brand/campaign registration, broadcasts with AI content review, contacts, AI agents with flows and RAG knowledge bases, serverless TypeScript functions (Zavu Cloud), and phone-number provisioning. Auth is API-key bearer tokens with test (zv_test_) and live (zv_live_) modes, idempotency keys, cursor pagination, and per-project rate limiting. Official SDKs ship for TypeScript, Python, Ruby, Go, and PHP, plus an official MCP server. Zavu is a 500 Global portfolio company.
