## 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 cryptyx-factor-cross-section-b10ee19e
```

Example prompt: Pull the full market factor cross-section from CRYPTYX and show me the top-ranked assets by t-score right now — I want to see which coins are leading across factor classes.

## When to prefer this

Use this endpoint when you need a quantitative, multi-factor ranking or scoring of crypto assets — especially for systematic/quant strategies, asset screening, or identifying factor-driven leaders. Prefer over generic price or sentiment APIs when t-score or factor-class granularity is required.

## Known failure modes

- Invalid mode value (not 'market' or 'asset') returns 400
- Unknown asset symbol returns empty or 404
- Payment not completed returns 402
- Rate limit exceeded returns 429
- Service unavailable during maintenance returns 503

## How this service works

Factor term-structure grid — 7 classes by 8 horizons of market-average t-score with breadth counts and 1-day momentum delta. Per-asset mode adds delta-vs-market per cell. Read rotation in one matrix. Runs across 200+ digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.

## Output

Returns an array of assets ranked by factor signal strength, each with a rank integer, asset symbol, factor class code (e.g. TR for trend), and a t-score indicating signal magnitude.
