How this service works
ENS resolve — turn a .eth name into an address, or an address into its primary .eth name, via eth_call on OneSource live Ethereum RPC
Output
Returns the resolved Ethereum address for a given .eth name, or the primary .eth ENS name for a given 0x address, fetched via a real-time eth_call against the OneSource Ethereum RPC node — including chain-related metadata.
Example use cases
Verify wallet identity before payment
“I need to send funds to swollen.eth but want to double-check the actual wallet address it points to on-chain right now. Can you resolve that for me?”
Look up ENS name from wallet
“My user just connected their wallet 0x1234567890abcdef1234567890abcdef12345678 — do they have a primary ENS name registered?”
Cross-chain ENS resolution for airdrops
“We're distributing tokens to several .eth names on Base mainnet. Can you resolve each of those domains to their actual addresses on Base using live on-chain data?”
Technical details
Endpoint
GEThttps://skills.onesource.io/api/chain/ens/swollen.ethWhen to prefer
Choose this endpoint when you need live, authoritative on-chain ENS resolution without relying on cached third-party APIs. Ideal for forward resolution (.eth → address) or reverse resolution (address → .eth) against real Ethereum state. Prefer this over static lookup tables or indexer APIs when freshness and on-chain accuracy matter. Also supports Sepolia, Base, and other EVM-compatible networks with ENS deployments.
Side effects
- ENS name not registered or expired — returns null or empty address
- Address has no primary ENS name set — returns no reverse record
- Invalid input format (not a valid .eth name or 0x address) — input schema validation error
- Unsupported network specified — returns error for non-Ethereum networks that don't support ENS
- RPC node unavailable or timeout — returns 503 or connection error
- Payment not included or insufficient — returns HTTP 402 requiring x402 payment of $0.005 USDC
