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 corresponding Ethereum address (e.g. {"name": "vitalik.eth", "address": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"}).
Example use cases
Resolve ENS name before sending crypto
“Before I send ETH, can you look up what address vitalik.eth resolves to so I can double-check it's the right wallet?”
Verify ENS ownership for Web3 login
“I need to verify that the ENS name coinbase.eth actually maps to the address 0x123... — can you look it up and confirm?”
Enrich user profile with ENS name
“I have an Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — can you do a reverse ENS lookup and find out what .eth name is associated with it?”
Technical details
Endpoint
GEThttps://kollmz.site:8443/v1/chain/ens?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, no-account pay-per-call ENS resolution without setting up an Ethereum node or managing API keys. Ideal for agents that occasionally need to resolve .eth names or reverse-lookup addresses without committing to a subscription. The x402 micropayment model (USDC on Base) makes it cost-effective for low-volume or one-off lookups.
Side effects
- ENS name not registered or has no resolver — returns null address or error
- Invalid ENS name format — returns validation error
- Reverse lookup address has no associated ENS name — returns empty result
- Payment failure via x402 — request blocked before resolution
- Network/DNS issues reaching ENS infrastructure from Germany hub
