## 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 api-meckercapital-com-c023c6d9
```

Example prompt: Show me all the cointegrated crypto perpetual futures pairs that are at least GREEN regime quality — I want to see their z-scores and whether I should be long or short the spread right now.

## When to prefer this

Use this endpoint when you need a full-market scan of all currently tradeable cointegrated crypto pairs with regime quality filters — ideal for portfolio-level screening before drilling into individual pair details. Prefer this over the single-pair or ranked endpoints when you want the complete universe of cointegrated pairs and intend to apply your own downstream filtering or ranking logic.

## Known failure modes

- Invalid min_regime value returns 422 validation error
- No pairs meet the requested regime threshold — returns empty pairs array
- Payment not processed (x402) — returns 402 Payment Required
- Service temporarily unavailable — returns 503
- Stale data if cointegration engine has not refreshed recently

## How this service works

List all cointegrated crypto perpetual futures pairs for statistical arbitrage. Returns regime classification (GREEN/YELLOW/RED), z-score, and signal direction (LONG_SPREAD/SHORT_SPREAD/FLAT). Engle-Granger cointegration, mean reversion, market-neutral pair trading on crypto derivatives.

## Output

An array of cointegrated crypto perpetual futures pairs, each with pair_key, asset_a, asset_b, regime (GREEN/YELLOW/RED), z_score, signal (LONG_SPREAD/SHORT_SPREAD/FLAT), and last_updated timestamp, plus a meta object with summary statistics.
