How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object containing the original name, the chain it resolves on (e.g. 'ethereum'), the resolved wallet address (checksummed), and the resolver contract address used to perform the lookup.
Example use cases
Send crypto to a named wallet
“I want to send some USDC to vitalik.eth — can you resolve that ENS name to its actual Ethereum wallet address first?”
Verify a Basename before transacting
“Before I sign this transaction, can you look up the address that jesse.base.eth resolves to so I can confirm it's correct?”
Display human-readable identity in a dApp
“My app has a list of .eth and .base.eth usernames — can you resolve coinbase.base.eth to its underlying address so I can show the wallet info?”
Technical details
Endpoint
GEThttps://fastx402.tools/name-resolve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, no-account-required resolution of ENS (.eth) or Base (.base.eth) names to wallet addresses, especially inside an AI agent workflow where paying $0.002 per call in USDC via x402 is preferable to managing API keys or running your own resolver infrastructure.
Side effects
- Name does not exist or has not been registered — returns an error or empty address
- Name is expired and no longer resolves — may return null address
- Invalid format provided (not a valid ENS or Basename) — request validation error
- Network issues reaching ENS resolver contracts — timeout or 5xx error
- Name resolves to zero address if no address record is set
