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
A JSON object containing the resolved ENS name and its corresponding Ethereum address (e.g. {"name":"vitalik.eth","address":"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"}). For reverse lookups, returns the ENS name associated with the given address.
Example use cases
Resolve ENS before sending crypto
“Before I send funds, can you look up what Ethereum address friend.eth resolves to so I know I have the right wallet?”
Reverse lookup address to ENS name
“I have the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — can you check if it has an ENS name registered to it?”
Verify ENS name in Web3 app
“My app needs to verify that the ENS name alice.eth maps to the expected address 0xABC123 before allowing login — can you resolve alice.eth for me?”
Technical details
Endpoint
GEThttps://crystalbell.ccwu.cc:8443/v1/chain/ens?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-account-required ENS name resolution and are already operating in a Web3/x402 payment context. Ideal for agents that need to resolve .eth names on-demand without managing API keys or rate-limit subscriptions. The Europe Germany hub is best for latency-sensitive queries originating in or near Europe.
Side effects
- ENS name does not exist or has no resolver set — returns error or empty address
- Address has no reverse ENS record — returns null or empty name
- Malformed ENS name input (e.g. missing .eth suffix) — may return validation error
- Network or blockchain node unavailability — may return timeout or 5xx error
- Payment failure (insufficient USDC or x402 protocol issue) — returns 402 Payment Required
