How this service works
Everything cheap that is knowable about an address, in one call — Genesis402 / UnyKorn Operator Network
Output
A JSON object with ok: true, the summary type 'evm-address-summary', a receipt with transaction hash and amount paid, and a generated_at timestamp. The body contains aggregated cheap on-chain facts about the address: expected to include native token balance, ERC-20/token holdings, contract vs EOA classification, and activity indicators for the requested chain.
Example use cases
Quick wallet due diligence before payment
“Before I send funds, can you pull a full on-chain summary of 0xAbCd1234...5678 on Base so I can see what kind of address it is — tokens, activity, whether it's a contract?”
Portfolio snapshot for a known address
“I want to see everything cheaply knowable about the wallet 0x1234...abcd on Arbitrum — balances, tokens held, activity — all in one shot.”
Screening an address on Polygon for a dApp
“Run a full cheap address summary on 0xDead...Beef on Polygon for me — I need to know if it's a real active wallet or something suspicious before we allowlist it.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/evm-address-summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a broad, multi-faceted snapshot of an EVM address and want to minimize the number of API calls and cost. It bundles all 'cheap' lookups (balance, tokens, contract status, activity) into one $0.006 call across 10 major EVM chains. Prefer it over specialized siblings when you don't know in advance which facts you'll need, or when you want an efficient first pass before drilling into details.
Side effects
- Invalid address format (not a 0x + 40 hex chars) returns a validation error
- Unsupported chain value returns an enum error
- Payment failure (x402 micropayment not completed) returns 402 Payment Required
- Network/RPC timeout for the target chain may return a 5xx error
- Address with no on-chain history may return empty fields but still ok: true
