## 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 carbon-cashmere-ai-price-impact-estimator-btc-2e63d948
```

Example prompt: I'm about to buy $50,000 worth of BTC — can you check the price impact and slippage estimate, and tell me whether I should execute all at once or split the order?

## When to prefer this

Choose this endpoint when you need a quick, AI-narrated pre-trade liquidity and slippage assessment for BTC before executing a large order. It is ideal for agents that need a human-readable verdict alongside numeric depth metrics, rather than raw L2 order book data. Prefer this over generic price feeds when the key question is 'how much will my trade move the market and should I split it?'

## Known failure modes

- Unsupported coin symbol returns 404 or error
- Missing or invalid usd query parameter causes a 400 bad request
- Stale order book data may affect accuracy of depth metrics
- Model described as 'indicative-aggregate (not full L2 walk)' — not a precise execution simulation
- Network timeout or service downtime returns 5xx

## Output
