See it in action

Pair a phone with a code, then send a WhatsApp message with one API call.

Everything you need to ship

Built for developers who want WhatsApp integrations without the infrastructure pain.

Connect in 60 seconds

Scan a QR or use a pairing code. Your phone becomes an API. No jailbreak, no hosting WhatsApp yourself.

Your own subdomain

Every instance gets {name}.eai.menustudioai.com. White-label your API from day one.

The full WhatsApp API

Messages, media, stickers, polls, lists, groups, presence — the complete API surface.

Realtime WebSocket events

Stream messages and connection updates live over Socket.IO. No polling required.

Secure by default

Per-instance tokens, isolated instances on request, and per-user DNS records.

AI assistant included

Ask the built-in assistant to send a message, check an instance or find an endpoint.

From zero to sending messages

Three steps. No servers, no WhatsApp Business API approval.

One curl to send a message

Your instance token + your subdomain. That’s the whole integration surface. Media, stickers, polls, group management — same pattern.

Text, audio, images, documents
Groups & broadcast lists
Stickers, polls, interactive lists
Webhooks + WebSocket events

$ curl -X POST https://my-bot.eai.menustudioai.com/message/sendText \
  -H "apikey: 0e91…db63" \
  -H "Content-Type: application/json" \
  -d '{
    "number": "34600000000",
    "text": "Hello from Weai 👋"
  }'

{
  "key": {
    "remoteJid": "[email protected]",
    "fromMe": true
  },
  "message": { "conversation": "Hello from Weai 👋" },
  "messageType": "conversation"
}
