## 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-financial-briefing-api-591264f3
```

Example prompt: Pull me a full PreReason financial briefing for NVDA — latest figures, what changed, and the macro context — formatted as markdown so I can use it directly.

## When to prefer this

Choose this endpoint when you need a comprehensive, pre-reasoned financial briefing for a specific listed company — especially when feeding context to an AI agent that needs structured analysis without performing its own multi-step reasoning. It supports US tickers, CIKs, Japanese securities codes, Korean stock codes, and Indian ISINs, making it ideal for cross-border equity research. Prefer this over raw financial data APIs when you want reasoning already embedded in the output, saving token budget and agent reasoning steps.

## Known failure modes

- Invalid or unrecognized ticker/ISIN/stock code returns an error — ensure the company identifier matches the pattern ^[A-Za-z0-9.-]{1,33}$
- Company not covered by PreReason's database returns a 404 or empty briefing
- Payment failure (402) if x402 payment header is missing or insufficient — endpoint costs $0.35 USDC per call
- Stale data if the underlying market data source hasn't updated recently
- Invalid format parameter (not 'json' or 'markdown') may result in a default or error response

## How this service works

Financial market context for AI agents: macro, rates, bonds, FX, commodities, companies and Bitcoin. One API call returns a briefing with the reasoning already in it.

## Output

A structured financial briefing for the requested company, including latest reported financial figures, what has changed, macro and rates context relevant to the company, and pre-written reasoning narrative. Available in markdown (token-optimized for LLMs) or JSON (structured) format. The response includes entity metadata and a briefing identifier indicating which template version was used.
