How this service works
Machine-readable settlement service
Output
Returns a label or human-readable name associated with the given EVM address, potentially including entity name, tag, or category classification for the address.
Example use cases
Identify unknown wallet in transaction
“I see this address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 showing up in my transaction history — can you find the label or entity name for it so I know who I was transacting with?”
Enrich DeFi analytics dashboard
“I'm building a DeFi analytics report and need human-readable labels for these contract addresses on EVM chains — start with 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D so I can display a proper name instead of a raw hex string.”
Flag suspicious address in compliance review
“During a compliance check I found this address 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — can you resolve its label so I can note the associated entity in my report?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/mini/evm.address-label--evm-address-labelWhen to prefer
Use this endpoint when you need a quick, pay-per-call resolution of EVM address labels without managing your own address database. Ideal for enriching transaction records, analytics pipelines, or compliance workflows where occasional address lookups are needed and a flat $0.002 micropayment model fits better than a subscription. Prefer alternatives if you need bulk batch resolution or real-time ENS name resolution specifically.
Side effects
- Address not found in label database — returns empty or null label
- Invalid EVM address format in input — may return error or empty result
- Unknown or newly created addresses with no label data — returns no label
- Network or service availability issues returning 402 or 5xx errors
- Payment failure due to insufficient USDC balance for the $0.002 per-call fee
