Do I need an account to use them?

No. They run in the browser. We don’t ask for login or store the number you type on our servers.

Is the QR generator a separate page?

No. The wa.me link and QR code live in the same tool: copy the link or download the PNG.

Do these tools replace Cloud API?

No. wa.me and QR open the chat. Cloud API + agent handle after, with coexistence if the business still uses WhatsApp Business and WhatsApp Web.

What next when the lead writes?

A white-label agent on 42agents, from USD 39 per account. 7-day free trial; signup is available in the dashboard.

42agents tools are free and require no login: wa.me link + QR code, a USD WhatsApp API message calculator (Meta rate card), and an E.164 format checker. They cover everyday work and lead to the product: an AI agent on that same number, under your agency’s brand.

What problems they solve

An ad or storefront sends people to WhatsApp and the link is broken or the QR does not open the chat.
You need to estimate Meta fees for a proposal and there is no easy official calculator.
Numbers arrive with trunk zeros, Argentine 15, or Mexican 044 and the wa.me fails.
There is no clear bridge from a free tool to a white-label agent on Cloud API.

Who they are for

Marketing agencies

They build wa.me links and QR codes for ads, landings, and stores, and quote Cloud API messages in USD before talking retainer.

AI agencies and software houses

They validate E.164, estimate order-of-magnitude Meta fees, and avoid rebuilding WhatsApp connectors for every client.

Companies and storefronts

They put a link or QR on the number they already use. Next step: an agent with coexistence, bought direct or through an agency.

What this set includes

wa.me link + QR

One tool: copy the link, download the PNG, and the prefilled message is in both.

USD calculator

Per-message cost from Meta’s rate card (October 1, 2026), with volume tiers. Always in US dollars.

E.164 verifier

International format and LatAm tips. Does not confirm the number has WhatsApp.
