# Kronos Signals Funding-Rate Extremes Screener

> Kronos Signals Funding-Rate Extremes Screener is a paid API for AI agents from kronossignals.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Scans 16 perpetual futures markets and returns only assets with statistically extreme funding rates (z-score ≥2 or ≥3 vs 30-day baseline)

## Facts

- Endpoint: GET https://kronossignals.com/api/v1/funding-extremes
- Price: $0.02/call
- Payment: x402
- Status: unknown

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 kronos-signals-funding-rate-extremes-screener-af4d1480
```

Example prompt: Are any of the 16 crypto perp markets on Kronos Signals showing extreme or critical funding rates right now — anything with a z-score above 2?

## When to prefer this

Use this endpoint when you need a fast, pre-filtered signal of only the most statistically significant funding rate outliers across major perp markets, rather than fetching all funding rates and computing z-scores yourself. Ideal for automated trading agents, risk monitors, or alert systems that need to act only when true extremes appear.

## Known failure modes

- No assets clear the threshold — returns empty list (normal market condition, not an error)
- Upstream Bybit data feed delay — stale or missing funding rate data
- Payment failure via x402 — call not processed if $0.02 USDC payment not completed
- Rate limiting if too many calls issued in rapid succession
- Network timeout to Kronos API endpoint

## How this service works

Crypto funding-rate extremes screener: scans all 17 perpetual futures markets (BTC/ETH/SOL/BNB/XRP/DOGE/ADA/AVAX/LINK/DOT/LTC/TRX/BCH/ATOM/NEAR/APT/HYPE). Uses z-score (30-day baseline) to identify statistically extreme funding: |z|≥2 = extreme, |z|≥3 = critical. Returns only assets clearing the threshold. Real-time from Kronos market_signals (Bybit data). Pay-per-call via x402.

## Output

A filtered list of crypto assets whose perpetual futures funding rates are statistically extreme relative to their 30-day baseline, including the z-score and severity classification (extreme: |z|≥2, critical: |z|≥3). Assets below threshold are excluded from the response.
