How this service works
108 production APIs behind HTTP 402 micropayments. 72 LLMs, Kling V3 and Hailuo video generation, image generation, code execution, travel search, web scraping, TTS, and transaction simulation. Pay with USDC on Base, USDm on MegaETH, or USDC on Solana.
Output
Returns the resolved Ethereum address (0x format) and any associated ENS records for the given .eth name, allowing identification of the on-chain wallet or contract the name points to.
Example use cases
Wallet address lookup before payment
“Before I send ETH to rainbow.eth, can you resolve that ENS name and give me the actual 0x address it maps to so I can double-check it's correct?”
ENS name verification for dApp integration
“I need to verify what Ethereum address the ENS name myproject.eth currently resolves to — can you look that up for me?”
User profile enrichment with ENS
“I have a user who signed in with their ENS name brantly.eth — can you resolve it to its Ethereum address so I can associate it with their account?”
Technical details
Endpoint
GEThttps://x402engine.app/api/ens/resolveWhen to prefer
Use this endpoint when you need to programmatically resolve a human-readable ENS name (.eth domain) to its underlying Ethereum address, especially within an AI agent workflow that needs to handle crypto payments or identity lookups without maintaining ENS resolution infrastructure. Preferred over running your own ENS resolver node when pay-per-call pricing at $0.001 USDC is more economical than self-hosted infra.
Side effects
- ENS name does not exist or is unregistered — returns null or error
- ENS name has no resolver set — cannot resolve to an address
- Network issues preventing on-chain lookup — timeout or connection error
- Invalid ENS name format provided — validation error
- Payment failure via x402 micropayment — 402 response if USDC balance insufficient
