## 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 prereason-company-briefing-51e30d43
```

Example prompt: Give me a full financial briefing on NVDA — latest reported figures, what changed, valuation, and how it's financed, in markdown format.

## When to prefer this

Choose this endpoint when you need a single-call, dated and sourced financial briefing for one public company — covering financials, changes, situation, valuation, and financing together. Prefer this over generic financial APIs when you need LLM-ready markdown output or structured JSON for US, Japanese, Korean, or Indian equities, and want every figure attributed to its source and reporting date.

## Known failure modes

- Unknown or unsupported ticker/code returns an error or empty result
- Malformed company identifier (outside pattern ^[A-Za-z0-9.-]{1,33}$) rejected with validation error
- Company from unsupported market returns no data
- Stale data if company has not filed recent reports
- Payment failure (x402) if USDC balance is insufficient

## How this service works

One listed company's briefing, every block in one call: its latest reported figures, what changed, its situations, and how it is valued and financed, each figure dated and sourced. Sold for USA, Japanese, Korean and Indian companies. The whole briefing is $0.35 a call and one block $0.05; the 11 blocks bought one by one come to $0.55. One block alone is GET /api/companies/{company}/{block}. Today's briefing only: this route takes no ?date=.

## Output

A structured or markdown-formatted briefing for one listed company covering: latest reported financial figures (revenue, earnings, etc.), what changed versus prior periods, the company's current situation, valuation metrics, and financing structure — each data point dated and sourced. Available for US, Japanese, Korean, and Indian listed companies.
