How this service works
Resolve an ENS name to its current Ethereum address or perform a reverse address lookup with forward-confirmation against the live ENS registry.
Output
A JSON object containing: success (boolean), network (e.g. 'mainnet'), mode ('forward' or 'reverse'), ens_name (the resolved or confirmed ENS name), and address (the resolved or confirmed 0x Ethereum address). For reverse lookups, forward-confirmation is performed to ensure the reverse record matches the forward record.
Example use cases
Forward resolve .eth name to address
“I need to send ETH to nick.eth — can you look up the current wallet address that ENS name resolves to before I send anything?”
Reverse lookup address to ENS name
“I have this Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — does it have an ENS name registered, and does the forward lookup confirm it?”
DApp identity verification flow
“My app just received the ENS name 'myuser.eth' from a user — can you confirm what address it currently resolves to on the live registry so I can verify it matches their connected wallet?”
Technical details
Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/ens_resolveWhen to prefer
Use this endpoint when you need a real-time, authoritative resolution of an ENS name to an Ethereum address (or reverse), with forward-confirmation to prevent spoofing. Prefer it over cached or aggregated ENS lookups when correctness and liveness matter — e.g., before sending funds, verifying user identity, or checking current ENS ownership. It is best suited for single-record lookups; for batch processing many names, consider an alternative approach.
Side effects
- ENS name not registered or has no resolver — returns success: false
- Address has no reverse ENS record set — returns success: false with empty ens_name
- ENS name forward and reverse records do not match — confirmation fails
- Invalid input format (malformed .eth name or non-hex address) — request error
- ENS registry temporarily unreachable — network or timeout error
