## 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 financial-data-x402-wallet-transaction-history-d3ed68e9
```

Example prompt: Pull the full transaction history for Ethereum wallet 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae so I can see every transfer it has made — who it sent to, how much ETH, and when.

## When to prefer this

Choose this endpoint when you need on-chain transaction history for a specific wallet address without signing up for an API key or subscription — ideal for autonomous AI agents that can pay per call in USDC via the x402 protocol. Prefer it over Etherscan API or Alchemy when you want frictionless micropayment access with no account management.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Address with no transaction history returns count:0 and an empty transactions array
- Network timeout or upstream node unavailability causes a 5xx error
- Payment failure via x402 (insufficient USDC balance) results in a 402 Payment Required response before data is returned
- Unsupported chain identifier may yield no results or an error

## 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 queried wallet address, the blockchain identifier (e.g. 'eth'), a count of returned transactions, and an array of transaction objects each including: to/from addresses, transaction hash, ETH value (decimal and wei), method called, gas used, gas price in wei, block number, timestamp (ISO 8601), and an is_error boolean flag.
