# Hedgehog Edge Inverse Backtest Runner

> Hedgehog Edge Inverse Backtest Runner is a paid API for AI agents from hedgehogedge.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-10-12).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 hedgehog-edge-inverse-backtest-runner-bc40ab5d -d '<json body>'
```

Example prompt: Run an inverse backtest on BTC/USDT using the golden_cross indicator on a daily timeframe from 2023-01-01 to 2024-01-01, with a trailing stop exit at 10% and 0.055% commission per trade.

## When to prefer this

Choose this endpoint when you specifically want to simulate an inverse (short/contrarian) strategy — i.e., entering short when a bullish signal fires and exiting on reversal or a stop condition. Use it over the standard backtest endpoint when testing bearish or contrarian hypotheses on BTC or ETH.

## Known failure modes

- Unsupported symbol (only BTC/USD, ETH/USD, BTC/USDT, ETH/USDT allowed) returns validation error
- Invalid indicator name not in enum returns 400
- Date range outside available historical data returns error or empty trades
- Invalid exitParams for chosen exitStrategy (e.g. missing percentage for trailing_stop) returns 422
- Payment not included or insufficient results in 402 Payment Required

## How this service works
