Zavu
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.
Zavu publishes 21 APIs on the APIs.io network, including 10DLC API, Account API, Agent Flows API, and 18 more. Tagged areas include Company, Messaging, SMS, WhatsApp, and Email.
The Zavu catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Zavu’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 25 more developer resources.
