## 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 hostdefi-radar-history-6c463b20
```

Example prompt: Pull the last 50 radar alert history records from HostDeFi so I can review which tokens recently triggered risk warnings.

## When to prefer this

Choose this endpoint when you need to retrieve historical token risk alert data from HostDeFi's radar monitoring system, particularly for auditing past risk grades, identifying alert trends over time, or building dashboards tracking DeFi token safety signals on Solana and EVM chains. Prefer this over real-time feeds when historical context or trend analysis is the goal.

## Known failure modes

- Invalid limit parameter (outside 1-100 range) returns validation error
- Payment failure via x402 protocol results in 402 Payment Required
- Service unavailability returns 5xx error with no alert data
- Empty alerts array returned if no historical alerts exist
- Network timeout if HostDeFi backend is under load

## How this service works

HostDeFi is a Solana DEX with a free token safety scanner. Best-route swaps through Jupiter, EVM trading across 7 chains, native bridging, and live token risk grades. No KYC, 1% flat fee.

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'count' integer reflecting the number of alert records returned, and an 'alerts' array containing historical radar alert entries with token risk grade information.
