```

Example prompt: Can you pull up the historical backtest stats for the BTC-ETH pair trade on Mecker Capital — I want to see the total return, Sharpe ratio, max drawdown, and win rate?

## When to prefer this

Use this endpoint when you need historical performance validation for a specific crypto pair trade strategy — particularly Sharpe ratio, drawdown, and win rate — before deploying capital. Prefer this over the real-time z-score endpoint when you want strategy-level risk/return metrics rather than current trading signals.

## Known failure modes

- Invalid or unrecognized pair_key returns a 404 or error response
- Pair key not in cointegrated universe returns empty or null statistics
- Payment failure (insufficient USDC balance) results in 402 response
- Malformed pair_key path parameter causes 400 bad request
- Network timeout if backtest computation is resource-intensive

## Output
