## 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-top-signals-d502ba17
```

Example prompt: Pull the top 10 CRYPTYX signals graded for a 14-day forward return horizon and tell me which ones have the best hit rate and mean expected return.

## When to prefer this

Use this endpoint when you need a ranked, pre-scored list of the highest-quality crypto trading signals with quantitative performance metrics. Prefer this over raw market data APIs when you want actionable, graded signals rather than unprocessed price or volume data. Best for agents making trading decisions or constructing a signal-driven investment thesis.

## Known failure modes

- Invalid horizon value (not 7d, 14d, or 30d) returns a 400 bad request
- Limit exceeds maximum allowed returns a 422 unprocessable entity
- Payment not included or insufficient returns a 402 payment required
- Service unavailable during market data refresh returns a 503
- No signals available for requested parameters returns an empty signals array

## How this service works

Top 10 atomic signals ranked by 7-day cross-sectional IC, gated to A/B health grades and non-anti-predictive names. Each carries trigger stats and a 7d walk-forward IS/OOS robustness block. Runs across 200+ digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.

## Output

A list of top-ranked signals, each including a letter grade (e.g. A), hit rate (e.g. 0.64), a signal identifier (e.g. VOL_COMPRESSION_7v30), and mean forward return (e.g. 8.5%) for the requested horizon.
