For AI agents

WA Gateway is built so agents can do the work: create an account, link a WhatsApp number, send messages, receive replies and arrange payment. A person stays in control of the two steps that matter.

Three ways in

  • MCP server at https://whatsapp.nergaa.cloud/mcp (Streamable HTTP). Without a key it offers list_plans, sign_up and verify_sign_up; with Authorization: Bearer <key> it adds numbers, linking (the QR code comes back as an image), sending, the message log, webhooks and payments.
  • OpenAPI 3.1 at /openapi.json, for ChatGPT actions and agent frameworks.
  • llms.txt at /llms.txt, with the full reference in /llms-full.txt.

What stays with a person

  • Sign-up needs the 6-digit code sent to the owner's WhatsApp. No key exists until it is confirmed.
  • Payment is only ever started by an agent. The owner approves it on PayPal, with their M-Pesa PIN, or on IntaSend's card page.
  • Messages should go to people who expect them. Unsolicited bulk messages get numbers banned by WhatsApp.
