How this service works
ENS resolution on Ethereum: name to address (vitalik.eth -> 0x...) or address to primary name, with round-trip verification of reverse records.
Output
Returns a JSON object containing the resolved Ethereum address (direccion), the matched ENS primary name (nombre_ens), and a block explorer URL (explorador) for the resolved address. Fields may be null if no record exists or verification fails.
Example use cases
ENS name to wallet address
“Look up the Ethereum address for aave.eth and verify the reverse record is valid.”
Wallet address to ENS name
“What is the primary ENS name registered to the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045?”
Pre-send ENS verification
“Before I send funds, can you resolve coinbase.eth to its actual 0x address and confirm the reverse record matches?”
Technical details
Endpoint
POSThttps://api.vextorium.com/ens-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve ENS names to Ethereum addresses or reverse-resolve addresses to .eth names on Ethereum mainnet, especially when round-trip verification of reverse records is important. Prefer it over generic Web3 libraries when you need a simple HTTP POST without managing your own Ethereum node or RPC connection.
Side effects
- ENS name not registered — returns null address
- Address has no primary ENS name set — returns null nombre_ens
- Reverse record mismatch — forward and reverse resolution disagree
- Invalid input format — non-ENS string and non-0x address
- Network RPC timeout causing lookup failure
- ENS name recently transferred with uncached records
