## 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 x402-finance-hub-trading-screener-21c5ca72 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need to screen or filter a large universe of financial instruments (stocks, forex, crypto) using technical or fundamental criteria and want multi-source data aggregation from Alpha Vantage, Twelve Data, and TradingView in a single call. Prefer it over single-asset quote endpoints when you need to discover instruments rather than look up a known one.

## Known failure modes

- Payment not received or insufficient USDC balance causes 402 rejection
- Upstream data provider (Alpha Vantage, Twelve Data) rate limit or outage causes 503
- Unsupported asset class or market segment returns empty results
- Malformed POST body causes 400 bad request
