## 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-eth-market-intelligence-api-d519eba9
```

Example prompt: What's the current ETH funding rate and is there any squeeze risk — give me the heuristic signal read including open interest trend and basis from Kronos Signals.

## When to prefer this

Use this endpoint when you need a real-time, pre-computed heuristic signal on ETH perpetual futures market conditions — specifically funding rate trend, OI dynamics, and squeeze risk — without having to aggregate raw exchange data yourself. Prefer this over raw exchange APIs when you want a concise, human-readable signal read alongside the underlying metrics. Best suited for agents making trading-adjacent decisions or monitoring ETH market structure on a per-call basis via x402 micropayments.

## Known failure modes

- Payment not received or x402 payment flow fails — endpoint returns 402 Payment Required
- Data source (Bybit) unavailable — available field may be false
- Stale data — data lags up to 5 minutes by design
- Invalid or malformed request — returns error response
- Rate limiting or overload on provider side

## How this service works

Real-time crypto derivatives signals for BTC/ETH/SOL/BNB/XRP/DOGE/ADA/AVAX/LINK/DOT/LTC/TRX/BCH/ATOM/NEAR/APT/HYPE-USD: perpetual futures funding rate (raw + annualized), next_funding_time, funding_interval_hours, open interest and 1h change, basis (perp vs index), funding-rate trend. Live data from Bybit/OKX via Kronos market_signals. Pay-per-call via x402.

## Output

A JSON object containing the ETH-USD perpetual futures market snapshot: funding rate (raw and annualized), funding trend (e.g. 'rising'), open interest and 1-hour OI change (absolute and percent), basis, mark price, index price, 24h volume, next funding time, data source (Bybit), timestamp, availability flag, and a plain-English heuristic signal read summarizing market conditions (e.g. crowded longs, squeeze risk). Includes a disclaimer that data may lag up to 5 minutes and is not financial advice.
