ENS Name/Address Resolution via EVM Public Node
x402
ENS Name/Address Resolution via EVM Public Node is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).
Resolves an ENS name to its EVM address (forward lookup) or an EVM address to its primary ENS name (reverse lookup), reading directly from a public node with no caching.

How this service works
An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.
Output
A JSON object with the resolved ENS name or address, whether the record was found, the block number at resolution time, chain and chainId, the resolver contract address, lookup direction, verified_forward flag (for reverse lookups), the public node host that answered, and an errors array listing any fields the node did not return. No USD pricing or cached data is included.
Example use cases
Forward resolve ENS to wallet address
“What 0x address does vitalik.eth map to on Ethereum mainnet right now? Look it up directly from a public node.”
Reverse lookup wallet address to ENS name
“What's the primary ENS name for the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045? Do a reverse lookup for me.”
Verify ENS forward resolution for a counterparty
“I'm about to send funds — can you confirm that alice.eth resolves to 0xAbC123... and that the name also resolves back to that address, so I know it's properly set up?”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/evm/ens?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, uncached, on-chain ENS resolution (forward or reverse) directly from a public EVM node, especially when freshness and block-level provenance matter. It is ideal for verifying counterparty identity before sending assets, enriching agent wallets with human-readable names, or confirming that an ENS name's forward and reverse records agree. Prefer alternatives if you need bulk resolution, cached/fast-path lookups where staleness is acceptable, or resolution across non-EVM naming systems.
Side effects
- ENS name not registered or has no resolver — found: false with reason explaining why
- Node did not return certain fields — those fields are null and listed in errors array
- Invalid 0x address format — rejected by input schema validation
- Name not found on the specified chain — found: false
- Public node timeout or unavailability — errors may list failed calls
