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 EVM address including: entity name and category from Open Labels Initiative consensus, is_contract and code_hash from on-chain data, reverse ENS or Basename for EOAs, OFAC/UK/EU/UN sanctions flags, scam/drainer flags, estimated address age, funder heuristics, and cited provenance with confidence scores. Unknown addresses return empty labels rather than an error.
Example use cases
Example prompt
“What is 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on Ethereum — is it a known protocol contract, and is it flagged for sanctions or scams?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/address/labels?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, fused identity profile for any EVM address in one call — combining protocol identity, sanctions screening, scam detection, ENS resolution, and on-chain metadata. Prefer it over separate lookups when you need trusted-attester consensus from Open Labels Initiative combined with real-time sanctions and fraud flags. Ideal for compliance checks, wallet profiling, dApp interactions, or any workflow where you need to know exactly what an address is before interacting with it.
Side effects
- Invalid address format (not 0x + 40 hex) returns validation error
- Unsupported network enum value returns error
- Unknown or unrecognized address returns empty labels (not 404)
- Payment failure (x402) if USDC balance insufficient
- Network timeout if on-chain RPC is slow
- Rate limiting if too many requests in quick succession
