Do I have to stop using WhatsApp on my phone?

No. Coexistence: the app and WhatsApp Web stay. The agent uses the official API on the same number.

How do I get this, and who implements it?

You can start with a 7-day free trial (any plan). Sign up at https://dashboard.42agents.app/sign-up to get started. Or go through a partner agency, if you already have one or prefer that path.

Does 42agents invoice me?

Yes, if you buy direct. If you go through an agency, the agency invoices you.

Can I bring my own OpenAI key?

Yes. On a direct signup we set it up with you. If you go through an agency, they can use their key or yours.

Does it work for a shop with a single number?

Yes. One account is one business: 1 line included and 3 users. You can add an extra line or user.

Your brand, your price, your client

From USD 39/account · 7-day free trial

42agents puts an AI agent and an inbox on your company’s WhatsApp number, with Cloud API and coexistence: nobody takes away WhatsApp Business or WhatsApp Web. It is not a chatbot on a brand-new number. You can buy from us directly: we implement and we invoice you. You can also go through a partner agency (marketing, AI, or a software house) under their brand. Platform cost starts at USD 39 per account per month. Meta conversation fees are extra. 7-day free trial; signup is available in the dashboard.

Company WhatsApp is the channel. There is no second shift.

Inbound sales dies in the owner’s personal chat.
Support repeats hours, prices, and “what’s the status of my order?” twelve times a day.
A 2019 Facebook chatbot does not understand the thread and cannot escalate to a human.
Changing numbers “because now it’s API” scares customers who already have you saved.

Who it is for

Companies with a WhatsApp that already answers people

Stores, clinics, real estate, support: one number, not a chatbot on a brand-new line.

Direct buy or through an agency

You can hire us, or your marketing, AI, or software agency can activate the account under their brand.

Small teams

One account includes 1 line and 3 users. Fine for a single location or a first pilot.

What this audience gets

Same number

Official coexistence. The team can stay on the phone.

Sales or support

You set the goal, tone, and a knowledge base. Nobody has to “know prompts.”

Handoff

If they ask for a human, the agent steps out. The thread does not reset.

What changes the day it goes live

The same number

Official coexistence. The team can stay on the phone. The agent joins in parallel.

Sales or support, on one screen

You configure what the agent is for, with tone and a knowledge base. Nobody has to “know prompts.”

A person can take the chat

If the customer asks for a human, or if your team hits Take, the agent steps out. The thread does not reset.

Buy direct or through your agency

There is a 7-day free trial on any plan. Signup is available in the dashboard. If you want to buy direct, start with signup. If you already work with a marketing, AI, or software agency, they can also activate an account under their brand. Your call.
