How this service works

Pay-per-call website uptime/latency/TLS checks and fetch-to-Markdown, measured from Hub Europe (Germany). USDC on Base via x402. No account or API key.

Output

Returns a JSON object containing the resolved ENS name and its corresponding Ethereum address (e.g. {"name": "vitalik.eth", "address": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"}). For forward lookups (name → address), both fields are populated. For reverse lookups (address → name), the name field reflects the registered ENS reverse record if one exists.

Example use cases

Resolve ENS name before sending crypto

“Before I send funds, can you resolve rainbow.eth to its actual Ethereum wallet address so I know I have the right destination?”

Reverse lookup from address to ENS

“I have this Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — can you check if it has an ENS name registered to it?”

Verify ENS identity in onboarding flow

“A user just signed in with the wallet address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B — can you check if that address has a human-readable ENS name I can display in their profile?”

When to prefer

Choose this endpoint when you need a lightweight, pay-per-call ENS resolution without setting up an API key or account. It is ideal for agents performing one-off lookups or low-volume resolution tasks, and is measured from Germany (Hub Europe), making it suitable for latency-sensitive workflows in Europe. Prefer it over self-hosted ENS resolvers when you want zero infrastructure overhead at $0.002 per call.

Side effects

ENS name not registered or has no address set — may return null address or empty result
Invalid ENS name format — malformed input rejected
Address provided for reverse lookup has no ENS reverse record set — name field may be empty or null
Network or RPC timeout when querying Ethereum mainnet — may result in transient errors
Payment failure via x402 — call not executed if USDC payment on Base is not settled
