Everyname provided a free-to-use API to fetch wallet addresses and on-chain names from any blockchain name service (ENS, Unstoppable Domains, and others).
Everyname (Everyname Inc) built a name-resolution API for web3, letting applications reverse- and forward-resolve addresses and domains across multiple blockchain name services with a single integration. The project is discontinued: everyname.xyz is a parked domain listed for sale, and the GitHub organization has been inactive since September 2023.
