## How to call it through Zero

```sh
zero fetch --capability api-meckercapital-com-d9311bfc

## When to prefer this

Use this endpoint when you need a ranked, ready-to-use list of the best current basis arbitrage opportunities across Extended Exchange and Hyperliquid, with full statistical validation (t-stat, hit rate, drawdown). Prefer this over the historical spread time-series endpoint when you want actionable signals rather than raw data, and over the pair cointegration endpoints when your focus is funding-rate carry rather than price mean-reversion.

## Known failure modes

- No opportunities meet the min_apr_pct filter — returns empty opportunities array
- limit out of range (must be 1–50) — returns 400 validation error
- Payment not provided or insufficient — returns 402 Payment Required
- Service temporarily unavailable — returns 503 error
- Stale market data may cause APR estimates to lag real-time conditions

## How this service works

Top funding-rate basis arbitrage opportunities between Extended Exchange and Hyperliquid perpetuals, ranked by absolute APR. Delta-neutral pairs trade: long one venue, short the other, capture cross-venue funding spread. Returns signed APR, t-stat, hit rate, worst-period APR, direction, and venue per leg. Cash-and-carry / funding-rate arbitrage on crypto perpetuals.

## Output

A ranked list of delta-neutral basis arbitrage opportunities, each with signed APR, t-statistic, hit rate, worst-period APR, trade direction (long/short), and which venue (Extended or Hyperliquid) to use per leg — filtered and sorted by absolute APR descending.
