## 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 vaunt-trade-evidence-evaluator-7e1c85ff
```

Example prompt: Pull Vaunt's trade evidence for going LONG on SOL with a 4-hour horizon — I want to see the win rate, mean move, favorable and adverse excursion, current regime, and whether Vaunt holds it.

## When to prefer this

Choose this endpoint when you need empirical, statistics-backed evidence from a live real-money trading engine before entering or validating a trade on Hyperliquid — especially when you want win rates, mean moves, excursion metrics, and regime context grounded in actual closed trades rather than backtested or simulated data. Prefer it over generic market data APIs when you specifically want Vaunt's proprietary trigger-matching methodology and posture signals.

## Known failure modes

- Asset ticker not listed on Hyperliquid returns an error or empty result
- Invalid direction enum (not LONG or SHORT) causes a schema validation error
- Unsupported horizon value (not 4 or 24) rejected by schema
- Insufficient historical triggers for the asset results in low-confidence or null statistics
- Payment failure via x402 protocol blocks the call
- Service downtime on Railway hosting causes 502/503 errors

## How this service works

Ask Vaunt: evidence for or against a proposed trade (asset + LONG/SHORT) from a live real-money trading engine on Hyperliquid — comparable triggers on independent days, mean move and win rate at 4h/24h, favorable/adverse excursion, class base rate, current regime and posture, whether Vaunt holds it, primary risk. Results only, never entry/stop/target.

## Output

Returns statistical results from Vaunt's live real-money trading engine including: number of comparable historical triggers, mean price move and win rate at the chosen horizon (4h or 24h), favorable and adverse excursion metrics, class base rate, current market regime and posture, whether Vaunt currently holds the asset in the proposed direction, and the primary identified risk. No entry, stop, or target prices are provided.
