ENS resolution: name->address (forward) or address->primary name (reverse). Ethereum mainnet.

Resolve ENS in either direction on Ethereum: an ENS name (vitalik.eth) → its 0x address, or a 0x address → its primary ENS name (plus avatar when set). The identity read wallet, payment, and UX agents make to verify who they're sending to or to show a human-readable name instead of a raw hex address. Free upstream (Blockscout ENS / live registry); one paid call instead of running your own resolver.

Look up an ENS name or an Ethereum address and get back the matching one, automatically figuring out which direction you need.

Returns one row per address with name (or null), displayName (with checksum if no name), and avatar URI. Use to label transaction lists, wallet leaderboards, or NFT holder snapshots with human-readable names instead of 0xabc… stubs.
