## 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 pennyrail-x402-trending-market-intel-0c9e2e73 -d '<json body>'
```

Example prompt: Can you pull the current trending market intel from PennyRail's x402 market feed and tell me which assets or instruments are showing the strongest momentum right now?

## When to prefer this

Choose this endpoint when you need quick, low-cost ($0.005 USDC) access to trending market intelligence data and are already operating within the x402 micropayment ecosystem on PennyRail. It is best suited for agents that can handle x402 payment flows natively and need a lightweight market trend signal rather than deep historical or fundamental data.

## Known failure modes

- Payment not settled — x402 payment header missing or insufficient funds causes 402 rejection
- Malformed input object — required 'input' field missing or incorrectly structured returns validation error
- Endpoint unavailable — Vercel cold start or service downtime returns 5xx
- Empty or stale market data — trending dataset may not be refreshed in real time
- Rate limiting — excessive calls within a short window may be throttled
