Fixed price per request (USDC)

0.01 USDC × 10⁶ = 10000 atomic units

How price matching works

Both ENS and HTTP 402 use this integer amount, on the same chain and token contract.

USDC recipient (ENS name owner)Recipient follows current ENS ownership. Contract holders additionally require proof of control on Base Sepolia before payments.Ops wallet (endpoint, description, picture, call schema)Treasury Admin (price and payment settings)

Publishing a service through this form costs Sepolia gas. Its API price is what future buyers pay per request. The namespace has a fixed expiry; parent administrators retain native override powers. This is not an independent mainnet .eth registration.

This older registrar requires two Sepolia transactions: start registration, wait at least 60 seconds after confirmation, then finish registration. The first transaction alone does not publish your service.

A different action / buying a name

Publish a service above. Call a service below.

The form above publishes an API. To call our paid-name API, an agent instead provides only a fresh order ID, label and recipient. In the current demo, this requests alice.ens402.eth for the recipient. It does not buy alice.eth. Public purchases remain unavailable until namespace and worker setup is complete.

{
  "orderId": "f1490e8a-5ae6-4e0b-becd-89920b597a88",
  "label": "alice",
  "recipient": "0x5555555555555555555555555555555555555555"
}

Illustrative values only. The SDK obtains HTTP 402, checks ENS terms and signs the exact request body before submitting payment.
