The record

Product: Zavu describes itself as a unified messaging API for sending and receiving communications across channels.
Inbox: The API exposes inbox threads sorted by recent activity and messages across each thread's channels.
Channels: Supported channels include WhatsApp, SMS, one-way SMS, voice, email, Telegram, Instagram and Messenger.
Routing: Zavu can automatically select a channel based on the recipient and the sender's configured channels.
AI agents: Agents can answer across messaging channels and phone, use agent-specific knowledge bases and memory, and call customer-owned tools.
Integrations: The maker lists TypeScript, Python, Ruby, Go and PHP SDKs, an MCP server, agent skills, a CLI, an n8n node and a Vercel Marketplace integration.
Planned integrations: Zapier, Make, HubSpot, Salesforce, Shopify, WooCommerce, Zendesk, Intercom and GitHub are marked Coming Soon on the integrations page.
Webhook security: The messaging API page says webhooks carry an X-Zavu-Signature using HMAC; v2, which signs the timestamp with the body, is the default for new senders.
Prepaid limit: Zavu says sending is rejected when the prepaid balance reaches zero, while inbound messages and webhooks keep working.
Free tier limit: The free plan allows two channel connections and 2,000 messages per month shared across WhatsApp, Telegram, Instagram and Messenger.
Support: Pro includes direct chat with Zavu engineers from 9am to 7pm Eastern Time, Monday to Friday; free users get an in-product assistant and Discord community.
Voice pricing: The pricing page lists voice agents from $0.07 per minute and says premium models and voices cost extra and BYOK is unavailable for voice agents.
Company: The privacy policy identifies the legal entity as Zavu Labs Inc., incorporated in Delaware, United States, and gives a Dover, Delaware business address.
Founder: The maker's homepage names Victor Villalobos as Founder & CEO of Zavu.
