# Carbon Cashmere AI Price-Impact Estimator

> Carbon Cashmere AI Price-Impact Estimator is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns an indicative price-impact estimate for a hypothetical crypto trade, including depth metrics, slippage estimate, severity tier, and Claude-powered microstructure analysis.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 api-carbon-cashmere-de-b042ba38
```

Example prompt: What's the estimated price impact and slippage if I place a $50,000 buy order on ETH right now — will it move the market much?

## When to prefer this

Use this endpoint when you need a quick, AI-narrated estimate of how much a hypothetical crypto trade will move the market before executing, especially for trade sizes over $10k where slippage materially matters. Prefer this over raw order book APIs when you want an opinionated severity classification and plain-language recommendation rather than raw depth arrays.

## Known failure modes

- Unsupported coin symbol returns 404 or error — only coins with available L2 depth data are supported
- Missing required query params (usd or side) returns 400 bad request
- Stale depth data if exchange feed is delayed — check data_age_seconds in response
- Large trade sizes may exceed available depth model range and produce unreliable estimates
- Payment failure (x402) if USDC balance insufficient

## How this service works

C&C · ai-price-impact — Indicative price-impact estimate for a hypothetical crypto trade via `?usd=50000&side=buy`. Returns depth metrics, slippage estimate, severity tier, and Claude microstructure analysis. Aggregate depth model.

## Output

Returns coin identifier, trade side, aggregate order book depth in USD, percentage of depth consumed by the trade, slippage estimate as a percentage and dollar amount, spread in basis points, severity tier classification, data age in seconds, source attribution, and a detailed Claude-generated microstructure narrative with execution recommendations.
