Resolves an ENS name (e.g. alice.eth, *.base.eth) to its Ethereum address by reading live from the ENS resolver on Ethereum mainnet

How this service works
Resolve an ENS name (like alice.eth) to its Ethereum address, read live from the ENS resolver on Ethereum mainnet. Offchain names such as *.base.eth resolve too. Returns `found:false` (a real answer, not an error) when the name has no address record. Live reads with automatic endpoint fallback.
Output
Returns the resolved Ethereum address for the given ENS name if found, along with a 'found' boolean. When the name has no address record, returns found:false (a definitive answer, not an error). Supports both mainnet .eth names and offchain names like *.base.eth, with automatic RPC endpoint fallback for reliability.
Example use cases
Resolve ENS before sending ETH
“I want to send some ETH to alice.eth — can you look up what Ethereum address that ENS name points to so I can confirm before I send?”
Verify a Base subdomain address
“What Ethereum address does jesse.base.eth resolve to? I need to check if it has an address record set.”
Validate user-submitted ENS name
“A user just entered degen.eth as their wallet address in our form — can you resolve it to an actual Ethereum address to verify it's valid and find out what it maps to?”
Technical details
Endpoint
POSThttps://chain.openverbs.com/v1/ens-resolveWhen to prefer
Use this endpoint when you need a live, authoritative forward resolution of an ENS name to its Ethereum address, especially when offchain names like *.base.eth are involved. Prefer this over cached or third-party ENS APIs when freshness and correctness matter (e.g., before sending a transaction). It explicitly signals found:false rather than throwing an error, making it safe and easy to handle unregistered names.
Side effects
- ENS name has no address record set — returns found:false (not an error)
- Malformed or non-existent ENS name — may return found:false or an error
- Mainnet RPC congestion — automatic fallback to secondary endpoint mitigates this
- Name exists but only has text records, not an address — returns found:false
