## 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-41f63181
```

Example prompt: What would be the price impact if I bought $50,000 worth of BTC right now — would I face significant slippage, or is the order book deep enough to absorb it cleanly?

## When to prefer this

Use this endpoint when an agent or user needs to pre-trade assess market impact before placing a large crypto order — especially when order size relative to available liquidity is unknown. It is preferable to a generic price feed when the question is not just 'what is the price' but 'what will happen to the price if I trade this size'. Best suited for trades where slippage and depth matter, not for small retail trades.

## Known failure modes

- Unsupported or unrecognized coin symbol returns an error or empty result
- Missing required usd query parameter may return a 400 or default behavior
- Stale or unavailable depth data may produce low-confidence estimates
- Payment failure (x402) blocks access if USDC payment not processed
- Very illiquid coins may return high-uncertainty estimates with wide confidence bands

## How this service works

Professional crypto market intelligence. Real-time prices, signals, and market scoring.

## Output

Returns a JSON object containing the coin symbol, trade side, USD amount, depth metrics (mid price, spread percentage, available depth in USD, trade size as percentage of depth), estimated impact (severity label such as 'minimal', estimated slippage percentage, model note), and a human-readable AI summary with a verdict on whether to execute immediately or split the order.
