How this service works
On-chain address identity label lookup on Base (100k+ curated entity labels). Pay per call with USDC via x402.
Output
Returns a human-readable identity label (e.g. organization name, protocol name, exchange name) associated with the queried Base blockchain address, drawn from a curated dataset of 100,000+ named entities. If no label exists, may return an empty or null result.
Example use cases
Identify counterparty in DeFi transaction
“I just received a transaction from 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD on Base — can you look up who that address belongs to so I know if it's a known DEX or protocol?”
Label unknown contract before interaction
“Before I interact with the contract at 0x2626664c2603336E57B271c5C0b26F421741e481 on Base, can you check if it has a known identity label so I know it's a legitimate project?”
Enrich on-chain analytics dashboard
“I have a list of Base addresses from my analytics report — can you look up the label for 0x4Dfe1EbbF22b694f5177a6B0b4aD8DA9e1FBF2ec so I can annotate who it belongs to in my dashboard?”

Choose this endpoint when you need to quickly resolve a Base blockchain address to a known human-readable entity label without running complex on-chain analytics. It is ideal for enriching transaction data, annotating dashboards, or performing counterparty due diligence on Base.
