## 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 x402stock-factor-score-8f5d34ec
```

Example prompt: Can you pull the quant factor scores for Apple — I want to see how it ranks on Value, Quality, Growth, and Momentum, plus the composite score, all from filing-grade fundamentals?

## When to prefer this

Use this endpoint when you need a structured, transparent, multi-dimensional quant factor breakdown for a specific US stock, especially when you want to understand Value, Quality, Growth, and Momentum in a single call with all underlying metrics exposed. Prefer this over raw fundamental data APIs when you need pre-computed, normalized scores (0–100) ready for comparison or ranking, and when filing-grade accuracy matters. It is not a recommendation engine — choose it for factual, quantitative analysis inputs.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Ticker exists but lacks sufficient fundamental data for scoring (e.g. pre-revenue company)
- Non-US or OTC stocks may not be supported
- Payment failure (insufficient USDC) blocks the request
- Rate limiting if called too frequently

## How this service works

A transparent quant factor score for a US stock: Value (P/E, P/S, P/B), Quality (ROE, margins, leverage), Growth (YoY revenue & earnings) and Momentum (trailing return), each 0–100 from filing-grade fundamentals plus an equal-weighted composite. Returns every metric it scored, with labels. Factual, not advice. From x402stock, a market & economic data API (x402, USDC).

## Output

A JSON object containing individual factor scores (Value, Quality, Growth, Momentum) each on a 0–100 scale, the equal-weighted composite score, and every underlying metric used in scoring (P/E, P/S, P/B, ROE, profit margins, leverage, YoY revenue growth, YoY earnings growth, trailing return), with labels. Data is derived from SEC filing-grade fundamentals.
