## 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-preview-1bb724b4
```

Example prompt: What's Vaunt's conviction on a LONG trade for SOL over the next 4 hours — is it strong, weak, or against, and is Vaunt actually holding it right now?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.001) top-level conviction label before committing to a deeper evaluation. It is ideal for filtering a watchlist or doing a first-pass triage on trade ideas. If you need the detailed evidence, comparable trades, or full trade history, use the evaluate or evidence sibling routes instead.

## Known failure modes

- Unknown or unsupported ticker returns UNKNOWN label or error
- Invalid direction enum value causes 400 bad request
- Horizon value outside allowed enum (4 or 24) causes validation error
- Live engine data temporarily unavailable may return stale or UNKNOWN signal
- Payment not processed or insufficient USDC balance results in 402 payment required

## How this service works

Vaunt preview: STRONG/MODERATE/WEAK/AGAINST/UNKNOWN for a proposed trade (asset + LONG/SHORT) with the one-line basis, current regime band and whether Vaunt holds it now — from a live real-money Hyperliquid engine. The label only; the comparables, base rate and trade history are on the evaluate and evidence routes.

## Output

A structured response containing: a conviction label (STRONG, MODERATE, WEAK, AGAINST, or UNKNOWN), a one-line basis explaining the rationale, the current regime band for the asset, and a boolean or flag indicating whether Vaunt's live real-money engine currently holds this position.
