## 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
zero fetch --capability wallet-overview-on-chain-portfolio-snapshot-073d90b8
```

Example prompt: Can you pull the on-chain overview for the wallet address 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae on Ethereum — I want to know its ETH balance, how old the wallet is, and when the first and last transactions happened?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call on-chain wallet summary without an API key or subscription — ideal for one-off due diligence, agentic workflows that check wallet provenance, or any scenario where you need balance + age + transaction history in a single call for an EVM address. Prefer over free RPC calls when you need enriched metadata (age, first tx) without assembling it yourself.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Address not found on the specified chain returns null fields
- x402 payment failure (insufficient USDC balance or unsupported chain) blocks the request
- Rate limiting or Vercel cold-start may cause occasional timeouts
- Very new wallets with no transactions may return null for first/last transaction fields

## 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

A JSON object containing: the as_of timestamp, the chain identifier (e.g. 'eth'), the queried address, a boolean indicating if it's a contract, the native token balance (float and wei string), the wallet's age in days, the date and hash of the first transaction, the date and hash of the last transaction, and the total transaction count.
