## 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 market-intelligence-api-us-equity-fundamentals-0c31aa74
```

Example prompt: Can you pull the fundamental financial data and signal for Apple (AAPL) — I want to know if it looks strong or weak based on the latest SEC filings?

## When to prefer this

Choose this endpoint when you need official, filing-backed fundamental financial data for a US-listed company — especially when you want a derived signal or score rather than raw price data. Prefer this over technical or price endpoints when the question is about company health, valuation, or long-term fundamentals. For crypto or FX instruments, use the sibling market data endpoints instead.

## Known failure modes

- Unknown or invalid ticker symbol returns a 404 and the call is not charged
- Ticker exists but has no SEC filings (e.g. foreign-listed or OTC-only) may return 404
- Network or service errors return standard 5xx responses
- Non-US tickers (e.g. crypto pairs like BTCUSD) will not be found — this endpoint covers US SEC-filing companies only

## How this service works

Stock fundamentals of a US company (e.g. AAPL, MSFT, NVDA): key financial figures and the latest filing from SEC regulatory filings, with a derived fundamental signal, score and interpretation. Use for the financials of a US-listed company.

## Output

A JSON response containing key financial figures derived from official SEC regulatory filings for the requested US-listed company, along with the most recent filing reference, a derived fundamental signal (e.g. bullish/bearish/neutral), a numeric fundamental score, and a plain-language interpretation of that score.
