Base Basename/ENS Resolver
x402
Base Basename/ENS Resolver is a paid API for AI agents from x402-data-api.bodhinindustries.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).
Resolves a Basename or ENS name to its on-chain address (or reverse-resolves an address to its primary Basename), with spoof-guard verification, computed live from the Base chain.

How this service works
Self-computed Base onchain toolkit for AI agents: ERC-20 safety scan, manipulation-resistant TWAP price oracle, gas/fee oracle, calldata decoder, token/address/contract intel, wallet approval-risk audit, and batch token triage — all computed live from raw Base chain, no third-party data.
Output
Returns whether the Basename/ENS resolved successfully, the resolved wallet address, the primary Basename (if reverse mode), an avatar URL if set, the direction of resolution (forward or reverse), a spoof-guard verified flag confirming the primary name resolves back to the queried address, the Base block height at query time, and an ISO-8601 timestamp — all computed live from the Base chain with no third-party data.
Example use cases
Verify sender identity before agent payment
“Before I send funds to this wallet, resolve the address they gave me to see if it has a verified Basename, and check that it actually resolves back to the same address so I know it's not spoofed.”
Look up user profile from blockchain handle
“This user said their Base name is alex.base.eth — can you resolve that to their actual wallet address and grab their avatar if they have one set?”
Authenticate transaction recipient safely
“The person wants me to transfer tokens to jesse.base.eth — what's the actual wallet address behind that name, and confirm the reverse lookup matches so there's no name spoofing happening?”
Technical details
Endpoint
GEThttps://x402-data-api.bodhinindustries.workers.dev/basenameWhen to prefer
Use this endpoint when you need trustless, live Basename/ENS resolution on Base L2 with built-in spoof-guard verification and no reliance on third-party indexers. Prefer it over centralized name services when on-chain freshness, anti-spoofing guarantees, and avatar record retrieval matter.
Side effects
- Name not registered or expired — resolved: false with a reason string
- Address has no primary Basename set — resolved: false
- Spoof detected — verified: false when reverse name doesn't resolve back to the queried address
- Malformed input (neither valid ENS/Basename nor 0x address) — error or resolved: false
- Base RPC unavailable — service error
