How this service works
Entity labeling: is this address an EOA, a (proxy) contract, a known protocol, or flagged as scam — with name and public tags. Send { address }.
Output
Returns the entity type (EOA, proxy contract, known protocol, or scam), a human-readable name if available, and any public tags associated with the address.
Example use cases
Example prompt

Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/compliance/labelWhen to prefer
Use this endpoint when you need to quickly classify an EVM address — distinguishing wallets from contracts, identifying known DeFi protocols by name, or screening for flagged scam addresses. Prefer this over general blockchain explorers when you need structured, machine-readable labeling for compliance or risk workflows.
Side effects
- Invalid or malformed address format returns a 400 error
- Unknown address with no label data returns empty name and tags
- Payment failure (x402) blocks the request
- Newly deployed contracts may not yet have labels
- Rate limiting or service downtime returns 5xx
