## 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 optix402-x402-marketplace-alerts-api-4b0506f1
```

Example prompt: Check the Optix402 marketplace intelligence alerts right now and tell me if there are any active alerts in the x402 ecosystem — especially anything related to market shifts or ecosystem health.

## When to prefer this

Use this endpoint when you need real-time alert notifications specifically for the x402 ecosystem — particularly for monitoring market intelligence anomalies, competitive shifts, or ecosystem health events in the x402 payment protocol marketplace. Prefer this over general analytics endpoints when you want push-style alert data rather than historical metrics.

## Known failure modes

- Empty alerts array returned when no active alerts exist
- Payment required error (402) if USDC payment of $0.08 is not provided
- Invalid properties filter parameter results in malformed request
- Service unavailable if Vercel deployment is down
- Stale or delayed data if underlying analytics pipeline is lagging
