Identifies an EVM address by resolving its protocol/entity identity, on-chain type, ENS/Basename, sanctions status, and scam flags in a single call

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: entity name and category from Open Labels Initiative attestations with attester consensus, on-chain flags (is_contract, code_hash), reverse ENS or Basename resolution, sanctions status across OFAC/UK/EU/UN lists, scam/drainer flags, and cited provenance. Unknown addresses return empty labels rather than an error.
Example use cases
Sanctions screening before transfer
“Before I send funds, check if 0x7f268357A8c2552623316e2562D90e642bB538E5 on Ethereum is on any OFAC, EU, or UN sanctions list and whether it's been flagged as a scam.”
DeFi protocol contract identification
“I'm interacting with 0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2 on Base — can you tell me which protocol this contract belongs to, its category, and whether it's a known trusted entity?”
Reverse ENS lookup for wallet
“What's the ENS or Basename for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum, and is it a regular wallet or a smart contract?”
Technical details
Endpoint
GEThttps://api.agentstools.dev/address/labels?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, single-call identity resolution for an EVM address — combining protocol/entity labeling from Open Labels Initiative attestations, on-chain contract detection, ENS/Basename resolution, and multi-jurisdiction sanctions + scam screening. Prefer it over chain-specific block explorers when you need multi-network support and compliance screening in one call, or over standalone ENS resolvers when you also need entity categorization and sanctions checking.
Side effects
- Invalid address format (not 0x + 40 hex) results in an error response
- Unsupported network enum value returns an error
- Unknown or unlabeled address returns empty label fields (not a 404)
- Network connectivity or upstream attestation service outage may delay or fail the response
- Payment failure (x402) if USDC balance is insufficient for the $0.02 fee
