## 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 heurist-mesh-yahoo-finance-market-overview-6c755cea -d '<json body>'
```

Example prompt: Is the US stock market currently open, and can you give me a quick benchmark summary of major indices for the US Yahoo Finance region?

## When to prefer this

Use this endpoint when you need a quick, lightweight check on whether a specific Yahoo Finance market region is open and want a compact benchmark index summary — especially useful for pre-trade checks, workflow triggers, or market-hours-aware automation. Prefer this over full historical OHLCV endpoints when you only need current status and top-level index context rather than detailed price history.

## Known failure modes

- Market data temporarily unavailable due to Yahoo Finance API downtime
- Payment failure via x402 protocol returns 402 status
- Request with missing region parameter may fail validation
