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 API contracts indexed 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 and 1 Spectral governance ruleset.
Zavu’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 27 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Accelerator Portfolios (Y Combinator, 500 Global, Antler participation) | distribution | 28.7 | - | 1 |
| Official SDKs on Packagist, pub.dev and Hex | distribution | 28.7 | - | 1 |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 1
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
