# CRYPTYX Signal Leaderboard

> CRYPTYX Signal Leaderboard is a paid API for AI agents from cryptyx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a ranked leaderboard of top-performing trading signals for digital assets, graded by information coefficient, hit rate, and forward return horizon.

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-signal-leaderboard-4fedff4d
```

Example prompt: Pull the top 10 signals from CRYPTYX's signal leaderboard ranked for a 30-day return horizon — I want to see which ones have the best grades and hit rates right now.

## When to prefer this

Use this endpoint when you need to identify which quantitative signals are currently performing best across digital assets for a specific forward return window. Ideal for agents building signal-driven trading strategies, screening for high-IC signals, or monitoring signal quality over time. Prefer this over general market data endpoints when the goal is signal ranking and grading rather than raw price or volume data.

## Known failure modes

- Invalid horizon value (not 7d, 14d, or 30d) returns a 400 error
- limit parameter out of range returns a 400 error
- No signals available for the requested horizon returns an empty array
- Payment failure or missing x402 payment header returns a 402 error
- Service unavailability returns a 503 error

## How this service works

Signal activity leaderboard over 7-365 days — per-signal trigger frequency, average confidence, assets triggered, and a per-horizon walk-forward IC/reliability block. Frequency and robustness in one pass. Runs across 200+ digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.

## Output

Returns an array of ranked signal objects, each containing a signal ID (e.g. VOL_COMPRESSION_7v30), an information coefficient (IC) indicating predictive power, a letter grade (e.g. A), and a hit rate indicating the fraction of times the signal correctly predicted direction — all sorted by performance for the requested forward return horizon.
