## 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 x402engine-wallet-transaction-history-fc90b7c0 -d '<json body>'
```

Example prompt: Pull the last 100 transactions with asset transfers and labels for the Ethereum wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to see everything it's been doing on-chain.

## When to prefer this

Choose this endpoint when you need labeled, structured transaction history for any wallet address on a supported blockchain, particularly when you want asset transfer details alongside human-readable labels. Prefer it over raw RPC calls or block explorers when you need a clean, agent-friendly JSON response with pre-labeled transactions, and when pay-per-call pricing ($0.005) is preferable to a monthly API subscription.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain name causes a lookup failure
- Limit parameter exceeding allowed maximum may be clamped or rejected
- Empty result set if wallet has no transaction history on the specified chain
- Payment failure (insufficient USDC balance) blocks the request with HTTP 402
