## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh

```

Example prompt: Can you pull up the on-chain wallet overview for 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae on Ethereum — I want to see the ETH balance, wallet age, and when it last transacted?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
