How this service works

Machine-readable settlement service

Output

Returns a human-readable label or name associated with the given EVM address, potentially including entity name, tag, or classification metadata describing who or what controls that address.

Example use cases

Identify unknown wallet in transaction

“I see a transfer from 0xBE0eB53F46cd790Cd13851d5EFf43D12404d33E8 in my logs — can you look up what label or name is attached to that EVM address?”

Enrich DeFi dashboard with address names

“For the address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 showing up in our DeFi analytics, can you fetch its human-readable label so we can display it properly instead of a raw hex string?”

Due diligence on counterparty address

“We're about to send funds to 0x47ac0Fb4F2D84898e4D9E7b4DaB3C24507a6D503 — can you check if there's a known label or identity attached to that Ethereum address before we proceed?”

When to prefer

Use this endpoint when you need to resolve a human-readable label for a specific EVM/Ethereum address and want a pay-per-call micropayment model via x402 rather than maintaining an API subscription. Prefer this over ENS-only resolvers when you need broader address labeling beyond ENS names.

Side effects

Address has no known label — returns empty or null label field
Invalid or malformed EVM address input — returns validation error
Address not indexed — service may return 404 or empty result
Network or service unavailability — HTTP 5xx response
Payment failure via x402 protocol — 402 response if payment not processed
