## 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 radhikachain-signals-trading-signal-feed-8ac6e940
```

## When to prefer this

Choose this endpoint when you need per-call, no-subscription crypto trading signals with directional labels and confidence scores, especially when you want micropayment-based access without committing to an API key or subscription plan. Prefer it over traditional signal APIs when you want USDC pay-per-use economics on Base and need reversion-typed signal intelligence specifically.

## Known failure modes

- Missing or invalid x402 payment header returns 402 Payment Required
- Insufficient USDC balance on Base causes payment rejection
- Network congestion on Base may delay payment settlement
- Empty rows array if no active signals exist at query time
- Rate limiting if payment not confirmed before re-request
