ChainScope ENS Resolve
x402
ChainScope ENS Resolve is a paid API for AI agents from chainsscope.duckdns.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Resolves an ENS (Ethereum Name Service) domain name to its corresponding Ethereum wallet address

How this service works
Turn a .eth name into an address, or an address into its primary .eth name -- one endpoint, auto-detects which direction based on the input. Ethereum mainnet only (ENS has no separate Base deployment).
Output
Returns a JSON object containing the original ENS query string, the resolved Ethereum wallet address (as a 0x hex string), and the canonical resolved name. If the ENS name cannot be resolved, resolved_address may be null.
Example use cases
Send crypto to ENS name
“I want to send ETH to friend.eth — can you resolve that ENS name to the actual 0x wallet address so I know where the funds will go?”
Verify identity behind ENS
“Someone told me their wallet is 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and that it belongs to vitalik.eth — can you resolve vitalik.eth and check if the address matches?”
Enrich transaction data with ENS
“I have a list of ENS names from a DAO vote — can you resolve uniswap.eth to its underlying Ethereum address so I can cross-reference it with on-chain transaction data?”
Technical details
Endpoint
POSThttps://chainsscope.duckdns.org/tools/ens-resolveWhen to prefer
Use this endpoint when you need to programmatically resolve a human-readable ENS domain (e.g. name.eth) to an Ethereum wallet address within a multi-chain intelligence workflow. Prefer this over building your own ENS resolution when you want a single consistent API interface that is part of a broader wallet and address intelligence suite. Ideal for AI agents that need to enrich transaction flows, verify identity, or route payments to ENS names without managing separate ENS library dependencies.
Side effects
- ENS name does not exist or has no resolver set — returns null address
- ENS name is expired or transferred — returns stale or no address
- Invalid input format (not a valid .eth name) — may return error or null
- Network issues reaching ENS registry — service timeout
- Rate limiting or payment failure — request rejected
