How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

Output

Returns a JSON object containing both the resolved Ethereum address (e.g. '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045') and the ENS name (e.g. 'vitalik.eth'). Either field may be null if no reverse record or ENS name is set for the given input.

Example use cases

ENS name to wallet address lookup

“I need to send some ETH to vitalik.eth — what's the actual 0x wallet address that resolves to?”

Reverse ENS lookup for a wallet

“I have this Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — does it have an ENS name attached to it?”

Verify ENS ownership before payment

“Before I send payment, can you confirm that friend.eth resolves to the address I was given, 0xAbc123...?”

Technical details

Endpoint

POSThttps://api.vextorium.com/v1/ens-resolve?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to bidirectionally resolve between ENS human-readable names and raw Ethereum 0x addresses in a pay-per-call, no-subscription model. Prefer it when building agents that handle ENS lookups alongside other on-chain data tasks via Vextorium's unified API, paying in USDC via x402.

Side effects

ENS name does not exist or is unregistered — address field returns null
0x address has no reverse ENS record set — ens_name field returns null
Malformed query (invalid ENS format or invalid hex address) — validation error
Network or RPC timeout causing resolution failure
ENS name expired and no longer resolves to an address
