## 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 x402-bazaar-token-transfer-history-for-wallet-ef735a83 -d '<json body>'
```

Example prompt: Pull the recent USDC transfer history for wallet 0xAbC123...def456 — I want to see each transfer's direction, amount, USD value, who it went to or came from, and the tx hash.

## When to prefer this

Use this endpoint when you need detailed, per-transaction token flow data for a specific wallet and token — especially for cost basis tracking, auditing inbound/outbound flows, or identifying counterparties. Prefer this over general portfolio endpoints when you need transaction-level granularity with USD values and timestamps.

## Known failure modes

- 402 Payment Required — agent must pay $0.01 USDC on Base to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Invalid or unrecognized wallet address returns an error or empty result
- Unsupported token or chain returns no data
- Covalent upstream unavailability causes timeout or empty response
- Malformed POST body results in 400 Bad Request
