How this service works
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.
Output
A JSON object containing the ENS name, the resolved Ethereum address (0x...), the query string, the resolution direction (name->address or address->name), the chain (ethereum), whether resolution succeeded (resolved: true/false), and an avatar URL if set.
Example use cases
Example prompt
“What Ethereum address does vitalik.eth resolve to? Pay the $0.001 USDC fee per the x402 protocol and give me the resolved address and whether it was successfully resolved.”
Technical details
Endpoint
GEThttps://store.agentexchange.work/chain/ensWhen to prefer
Use this endpoint when an AI agent needs to resolve ENS names to wallet addresses (or vice versa) on Ethereum with no API key or signup required, paying only $0.001 USDC per call via the x402 micropayment protocol. Prefer this over custom RPC integrations when operating in a pay-per-use agent context on Base.
Side effects
- ENS name not found or not registered — resolved: false returned
- Invalid ENS name format — may return error or unresolved result
- Address has no primary ENS name set — resolved: false for reverse lookups
- Network or RPC issues resolving on-chain data — service error
- Missing required query parameter (name or address) — bad request error
