How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object containing the resolved Ethereum address, the ENS name, an avatar URL, the direction of resolution (forward or reverse), and a timestamp of when the resolution was performed.
Example use cases
Resolve ENS before sending crypto
“Before I send ETH to vitalik.eth, can you look up what Ethereum address that ENS name actually maps to so I can confirm I'm sending to the right place?”
Reverse lookup for wallet labeling
“I have the Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — does it have an ENS name registered? I want to label it properly in my portfolio tracker.”
Fetch ENS avatar for profile display
“I'm building a leaderboard and need to show profile pictures — can you look up the ENS name nick.eth and get me the avatar URL associated with it?”
Technical details
Endpoint
GEThttps://klymax402.com/api/ens-resolver/api/resolveWhen to prefer
Use this endpoint when an agent needs to resolve a human-readable .eth name to a machine-readable Ethereum address, or perform a reverse lookup from an address back to an ENS name — especially when you also need avatar/profile metadata in the same call. Prefer this over raw on-chain calls when you want a simple REST interface with no RPC node setup required.
Side effects
- ENS name does not exist or is not registered — returns null or error for address field
- Ethereum address has no reverse ENS record set — name field will be empty
- Malformed ENS name or invalid Ethereum address format — likely returns a validation error
- ENS name exists but has no avatar set — avatar field will be null or empty
- Payment failure via x402 protocol — call not executed
