How this service works
Independent pre-purchase safety and reputation checks for x402 and MPP endpoints, plus keyless onchain data on Base. Accepts BOTH EIP-3009 and Circle Gateway credentials — only 141 of 788 Base-payable resources do, and a single-credential buyer is locked out of 53.8% of this market on one rail or 28.3% on the other. GET /v1/guard?url=&credential= answers whether the credential you carry can pay a given endpoint at all, before you try. Searching this market for "is this API endpoint a scam" returns registries and explorers but no dedicated service; that gap is what /v1/guard fills, inspecting an endpoint WITHOUT paying it and returning a go / test-with-minimum / do-not-pay verdict backed by onchain settlement history.
Output
A JSON object containing the resolved wallet address for a given ENS name or Basename, or the primary name associated with a given address. Returns onchain name record data sourced from Base without requiring any payment credentials.
Example use cases
Resolve Basename to wallet address
“Can you look up the wallet address for jesse.base.eth on Base? I need the actual 0x address it points to.”
Reverse resolve address to primary name
“I have the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — can you check if it has a primary ENS name or Basename associated with it?”
Verify ENS name before sending funds
“Before I send crypto, can you confirm what address vitalik.eth resolves to on Base so I know I have the right destination?”
Technical details
Endpoint
GEThttps://gkyf2bs3b4p35hwwg5zzsnejeu.srv.us/v1/onchain/name?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need keyless, no-payment-required resolution of ENS names or Basenames on Base. Ideal for agents that need to resolve human-readable Web3 identities to addresses (or vice versa) as a prerequisite step before payment or interaction, without needing EIP-3009 or Circle Gateway credentials.
Side effects
- Name not found or not registered — returns empty or null result
- Address has no primary name set — reverse resolution returns null
- Invalid or malformed ENS/Basename input — may return error or empty
- Network unavailability on Base — service returns 5xx error
- Name exists but points to no address (misconfigured record) — returns null address
