What it does
Whether a number is on WhatsApp and, if so: personal or business account, about text, country, linked devices and whether it runs on the Cloud API. Businesses add their public profile: name, description, categories, email, websites, address, coordinates, hours, join date and Facebook page. No photo; /v1/profile/full adds it. Query param: phone, with country code (e.g. +14155552671). Every answer is charged, “not on WhatsApp” included; a lookup WhatsApp does not answer is free.

For humans
You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
