How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
Returns a JSON object with: timestamp of the data snapshot, chain identifier, address, a boolean indicating if the address is a contract, native token balance (both in human-readable and wei units), wallet age in days, total transaction count, and the date/hash of the first and last transactions.
Example use cases
Due diligence on a counterparty wallet
“Before I send funds, can you check the on-chain profile of 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae — how old is the wallet, is it a contract, and when did it last transact?”
Whale wallet activity monitoring
“Look up the wallet overview for 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae on Ethereum — I want to know the current ETH balance and how many total transactions it has made.”
Identifying smart contract addresses
“Is 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae an Ethereum smart contract or an EOA, and what's its native ETH balance right now?”
Technical details
Endpoint
GEThttps://x402financialdata.com/wallet-overview/%7Baddress%7DWhen to prefer
Choose this endpoint when you need a quick, structured on-chain profile of an Ethereum wallet without needing full transaction history — ideal for due diligence, risk scoring, or enriching a user profile with blockchain data. It requires no API key or subscription and charges only $0.02 USDC per call via the x402 protocol, making it cost-effective for sporadic or agent-driven lookups. Prefer this over general blockchain explorers when you need machine-readable JSON output suitable for downstream agent reasoning.
Side effects
- Invalid or malformed Ethereum address returns an error response
- Address not found on the specified chain returns empty or null data
- Payment failure via x402 protocol (insufficient USDC) blocks the request
- Network or upstream data provider outage causes 5xx errors
- Very new addresses may show zero transaction count or missing first/last transaction data
