## 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 hypergrowth-fillshield-hip-4-readiness-pack-92f59dbc -d '<json body>'
```

Example prompt: Before I submit this long ETH-PERP order on Hyperliquid, run it through FillShield and get me the HIP-4 readiness pack — I need to know if it's safe to execute right now.

## When to prefer this

Use this endpoint when your AI agent needs a pre-submit execution guard specifically for Hyperliquid orders, particularly when using the HIP-4 standard and wanting to avoid bad fills. Prefer this over generic risk checks when operating in the Hyperliquid ecosystem and needing a micropayment-gated, agent-native decision artifact.

## Known failure modes

- Payment not included or insufficient (x402 payment required, 0.05 USDC per call)
- Missing or malformed order parameters returns 400 error
- Hyperliquid connectivity issues may delay or fail readiness assessment
- Order context outside supported HIP-4 schema returns validation error
- Rate limiting if too many requests sent in rapid succession
