## 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-btc-alerts-api-9989f620
```

Example prompt: Check the current Kronos Signals BTC alerts — I want to know if there are any extreme funding rate or squeeze risk conditions active right now for Bitcoin.

## When to prefer this

Use this endpoint when you need a quick, structured snapshot of Bitcoin derivatives market conditions — specifically funding rate extremes, open interest levels, and crowded-position regime signals — without building your own data pipeline. Best suited for agents that need a single paid-per-call heuristic signal about BTC market stress rather than a subscription feed or raw exchange data.

## Known failure modes

- Payment not included or insufficient — x402 payment required ($0.02 USDC) before data is returned
- Data lag — market state may be up to 5 minutes stale
- No active alerts — response returns empty active_alerts array when market is quiet
- Service unavailable — upstream data feed issues could cause endpoint downtime
- Invalid request format — malformed query parameters rejected

## How this service works

Real-time Bitcoin (BTC) market-regime alerts: volatility squeeze, breakout, funding-rate extreme, open-interest surge — derived from live derivatives data. Event feed for crypto trading agents. Pay-per-call via x402 on Base USDC.

## Output

A JSON object containing the current BTC-USD market state including: the current funding rate (8h and annualized), open interest, a human-readable regime description, and a list of active alerts (each with event type like 'funding_extreme', severity level, detection timestamp, and details like whether longs or shorts are paying). Data is marked as heuristic and may lag up to 5 minutes.
