## 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-sol-market-intelligence-api-21de66fc
```

Example prompt: What's the current Kronos signal for SOL — is funding elevated, is open interest growing, and is there a squeeze risk I should know about before trading?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.02 USDC) structured market-intelligence snapshot for SOL-USD perpetual futures — specifically when you want funding rate trend, open interest dynamics, and a pre-computed heuristic squeeze-risk assessment rather than raw tick data. Prefer this over generic data feeds when you want an opinionated signal with narrative context rather than just numbers.

## Known failure modes

- Payment not received or x402 flow fails — endpoint returns 402 Payment Required
- Stale data if Bybit feed lags beyond 5 minutes — noted in disclaimer
- Asset data temporarily unavailable — 'available' field returns false
- Malformed request parameters — 400 Bad Request
- Service downtime or upstream Bybit connectivity issue — 503 or timeout

## 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: a plain-English heuristic 'read' summarizing market conditions; funding rate and its annualized equivalent; funding trend direction (rising/falling); open interest with 1-hour absolute and percentage change; basis; mark and index prices; 24h volume; next funding timestamp; data source (Bybit); and a disclaimer that this is heuristic-only data with up to 5-minute lag.
