# Cryptyx Multi-Factor Composite Backtest

> Cryptyx Multi-Factor Composite Backtest is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Backtests a custom-weighted composite across 8 factor classes, returning per-day composite return series with Sharpe, Sortino, and max drawdown metrics.

## 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-multi-factor-composite-backtest-229c8771 -d '<json body>'
```

Example prompt: Run a backtest on Cryptyx from January 1 2023 to December 31 2024 using a composite where momentum weight is 1.5, value is 0.8, sentiment is 1.2, and all other factor classes are set to 1.0 — I want to see the daily return series plus Sharpe, Sortino, and max drawdown.

## When to prefer this

Use this endpoint when you need to evaluate a specific multi-factor weighting scheme across Cryptyx's 8 factor classes before committing to a live composite strategy. It is the right choice when you want per-day return granularity combined with Sharpe, Sortino, and max drawdown in one call, and when you have a custom weight hypothesis to validate. Prefer this over single-metric or intersection backtests when the goal is holistic composite-level performance rather than isolated signal testing.

## Known failure modes

- Invalid or missing 'from'/'to' date fields returns a 400 error
- Factor class weights outside the allowed 0-2 range may be rejected or clamped
- Date range exceeding available 5+ year history may return partial data or an error
- Malformed weights object (wrong keys or non-numeric values) returns a validation error
- Insufficient historical data for the specified window returns an empty or truncated series

## Output

A JSON object containing a per-day composite return series (each entry has a date and composite_return float) along with aggregate risk-adjusted performance metrics: Sharpe ratio, Sortino ratio, and maximum drawdown — computed over the requested date range using the supplied factor class weights.
