## 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 finance-toonhaus-dev-eb26900e
```

Example prompt: Pull up the key financial metrics for NVDA — I want to see the P/E, PEG ratio, profit margins, ROE, and beta so I can evaluate whether it's overvalued.

## When to prefer this

Use this endpoint when you need quantitative fundamental valuation metrics (P/E, PEG, margins, ROE, beta, growth) for a single stock. Prefer this over earnings date or analyst recommendation endpoints when the goal is intrinsic valuation or screening by financial ratios rather than sentiment or timing.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Metrics unavailable for OTC/penny stocks or non-US equities
- Stale data if provider feed is delayed
- Missing fields for companies without sufficient financial history (e.g. pre-revenue startups)
- Rate limiting if too many requests are made in a short period
