## 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 signalharness-wallet-asset-flows-9915ff48 -d '<json body>'
```

Example prompt: Can you analyze the asset flows for wallet 0xAbC123...def456 on Base — I want to understand where funds are coming from and going to, and flag anything unusual.

## When to prefer this

Choose this endpoint when you need structured, agent-native analysis of wallet asset flows on Base (eip155:8453) with built-in payment via x402 and cryptographically verifiable receipts. Prefer it over generic blockchain explorers when you need a single API call that combines analysis, receipting, and warning flags in one response, especially in autonomous agent workflows that require auditability.

## Known failure modes

- Malformed or empty wallet_asset_flow_request string returns a validation error
- Wallet address not found or no on-chain data available may return empty flows with warnings
- Payment failure (insufficient USDC balance or x402 protocol error) blocks execution
- Ambiguous or overly broad query may return results with warnings about evidence scope limitations
- Network congestion on Base may increase latency or cause timeout

## Output

Returns a JSON object containing: a 'wallet_asset_flows' field with the analysis result, a list of any warnings encountered, the evidence scope indicating how data was sourced (e.g. caller-supplied data), a status field ('succeeded' or otherwise), and a full receipt including payment ID, network (Base/eip155:8453), latency, execution ID, and a SHA-256 hash of the result for verification.
