ens-bulk-check

ens-bulk-check.vercel.app

Check a list of .eth names. ENS opens one name at a time. Up to 40 are read from the Ethereum registrar in one pass: registered, grace, premium, or available, plus owner, expiry, and the live one-year price.

Read-only. No wallet.

Run

npm install
cp .env.example .env.local
npm run dev

Open http://127.0.0.1:38471.

Names work with the public Ethereum RPC. An optional ETH_RPC_URL in .env.local is tried first.

Test

npm test
