EVM Address Labels & Identity Lookup
x402
EVM Address Labels & Identity Lookup is a paid API for AI agents from webtools402.176-109-107-191.sslip.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).
Identifies an EVM address by combining Open Labels Initiative attestations, on-chain contract detection, reverse ENS/Basename resolution, and sanctions/scam screening into a single enriched label response.

How this service works
Identify what an EVM address IS in one keyless call: contract/protocol identity (entity, name, category) from Open Labels Initiative attestations with trusted-attester consensus, plus on-chain truth (is_contract, code_hash), reverse ENS/Basename, sanctions (OFAC/UK/EU/UN) and scam-drainer flags. Cited provenance; unknown addresses answer with empty labels, never a 404.
Output
Returns a structured label object for the queried address including: protocol entity name and category from Open Labels Initiative (with attester consensus and provenance citations), is_contract boolean and code_hash from on-chain truth, reverse ENS name and/or Basename, sanctions flags across OFAC/UK/EU/UN lists, and scam/drainer boolean. Unknown addresses return empty label fields rather than a 404.
Example use cases
DeFi protocol due diligence
“Before I interact with this contract at 0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45 on Ethereum, can you tell me what protocol it belongs to, what category it is, and whether it's flagged as a scam or on any sanctions list?”
Sanctions compliance check for crypto payment
“I'm about to send funds to 0x1da5821544e25c636c1417Ba96Ade4Cf6D2f9B5A on Ethereum — can you check if this address appears on OFAC, UK, EU, or UN sanctions lists before I proceed?”
Wallet identity resolution for user profile
“Can you look up the ENS name and any known identity labels for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum so I can display a human-readable name in my app?”

Endpoint
GEThttps://webtools402.176-109-107-191.sslip.io/address/labels?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, one-call identity and risk profile for an EVM address that combines protocol labeling, on-chain contract detection, ENS resolution, and sanctions screening together. Prefer it over the sibling sanctions-screen-address endpoint when you need more than just sanctions data — i.e., when you also want to know what a contract IS (protocol name, category). Use the sibling onchain-code endpoint instead if you only need EOA-vs-contract detection without identity or compliance enrichment.
Side effects
- Invalid address format (not 0x + 40 hex) returns an error
- Unsupported network value returns validation error
- Unknown/unlabeled address returns empty labels (not an error)
- Network connectivity issues to on-chain RPC or attestation sources may cause partial results
- Payment failure (x402) returns 402 before any data is returned
