# Cryptyx Factor Cross-Section Matrix

> Cryptyx Factor Cross-Section Matrix is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Returns an asset × factor-class t-score matrix with per-class rankings across the full ~200-asset universe for factor-tilt construction and momentum screening.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-matrix-1bfff892
```

Example prompt: Show me the full factor cross-section matrix right now — I want to see which assets across the entire universe have the highest t-scores by factor class so I can find the strongest momentum plays for a factor-tilt trade.

## When to prefer this

Use this endpoint when you need a broad cross-sectional view of factor signals across the entire ~200-asset crypto universe — ideal for factor-tilt portfolio construction, sector rotation decisions, or screening for the strongest momentum assets at a glance. Prefer this over single-asset endpoints when you need to compare and rank assets against each other rather than analyzing one asset in depth.

## Known failure modes

- Invalid mode parameter returns 400 with schema error
- Unknown asset symbol when using asset mode returns empty or 404
- Payment not processed (x402) returns 402 Payment Required
- Rate limit exceeded returns 429
- Service unavailable during market data refresh returns 503

## How this service works

Returns a market factor cross-section grid across classes and horizons, with average t-scores, asset counts, positive/negative counts, and momentum deltas. Useful for quickly scanning factor strength and breadth over time.

## Output

A list of asset-factor entries each containing the asset symbol, factor class label (e.g. TR for trend), t-score, and rank within that factor class — covering approximately 200 assets sorted by strength of factor signal.
