## 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 forecast-court-independent-verification-receipt-scriptmasterlabs-8695300a
```

Example prompt: Pull a Forecast Court verified audit receipt for the GME symbol using the sml-fractal strategy — I want to see whether its directional accuracy actually beats the always-up baseline.

## When to prefer this

Choose this endpoint when you need an independently computed, cryptographically receipted audit of a named strategy's directional accuracy on a supported ticker — especially when you want a same-window always-up baseline comparison for apples-to-apples evaluation. Prefer this over self-reported accuracy claims or backtests provided by the strategy vendor themselves.

## Known failure modes

- Symbol not in allowed enum (GME, AMC, IWM, SPY, QQQ, NVDA, TSLA) → 400 validation error
- Strategy key does not match pattern ^[a-z0-9][a-z0-9-]{2,39}$ → 400 schema error
- Fewer than 20 resolved observations for the strategy/symbol combination → not chargeable, likely returns a 402 or rejection indicating insufficient sample
- Payment not provided or rejected → 402 Payment Required
- Strategy key not found on selected symbol → 404 or empty audit result
- Non-GME symbols may return unchargeable status until their 20-outcome threshold is met

## How this service works

x402 pay-per-call APIs, MCP servers and practical AI field guides from a veteran-owned lab. Verify the provider, then pay per accepted call.

## Output

A JSON object containing: model directional accuracy ratio, always-up baseline ratio, independently recomputed sample count (minimum 20), integrity flags (source aggregate consistency, deep raw recalculation flag, public hash disclaimer), schema version, protocol version, price in USDC, and a SHA-256 hash of the response body — all wrapped in an accepted_delivery envelope.
