## 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-e6a3bb32
```

Example prompt: Pull the last 50 radar alerts from HostDeFi's token safety scanner so I can review recent token risk events on Solana.

## When to prefer this

Use this endpoint when you need a historical log of token safety scan results and risk alerts from HostDeFi's Radar system, particularly for Solana tokens. Prefer this over real-time scan endpoints when auditing past events, monitoring alert frequency over time, or building dashboards of token safety history.

## Known failure modes

- Invalid limit value (outside 1-100 range) returns a validation error
- Payment not completed or insufficient USDC balance returns 402 Payment Required
- Service unavailable returns 5xx error with no alert data
- Empty alerts array returned if no radar events have been recorded yet

## 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, a 'count' integer indicating number of records returned, and an 'alerts' array containing historical token safety scan alert objects from the HostDeFi Radar scanner.
