How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns the resolved wallet address and associated metadata for the given blockchain name, potentially including which registry it was resolved from and any additional name records associated with the identity.
Example use cases
Resolving ENS to send crypto
“Before I send funds, can you look up what wallet address vitalik.eth resolves to?”
Cross-registry Web3 name lookup
“I just have the name 'toly' — can you search all blockchain name registries and tell me what address it maps to?”
BNB name resolution for DeFi
“What on-chain address does cz.bnb point to? I need it to interact with a DeFi protocol.”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/tools/name-service/resolveName?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a human-readable blockchain name (ENS, SNS, BNB, ARB, or other Web3 namespace) to a wallet address, especially if you want cross-registry resolution in a single call without managing API keys. Ideal for DeFi agents that need to translate user-supplied names before executing transactions. The pay-per-request USDC model via x402 makes it suitable for low-volume or sporadic lookups without subscription overhead.
Side effects
- Name not registered in any supported registry — returns not-found or null address
- Ambiguous bare name with multiple matches across registries — may return multiple results or require disambiguation
- Network timeout or registry RPC failure — returns an error response
- Payment failure via x402 — request rejected before resolution attempt
- Malformed name input — validation error returned
