Chain Ens

by FiatDock in Weather & location

x402 APIPassing, checked 2 h ago

Resolve an ENS name or Basename to its address (vitalik.eth, jesse.base.eth), or an address to its primary name - verified to resolve back - with the profile records the owner published: url, X/Twitter, GitHub, description, avatar. Read from Ethereum mainnet through the ENS Universal Resolver; off-chain gateways go through our SSRF guard. ASCII names. Send {} for the published example. A name with no address is not charged. Pay-per-call via x402.
