- Price: $0.15/call
- Payment: x402
- Status: unknown

## 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-signal-api-eth-bundle-e0a185a8
```

Example prompt: What's Ethereum's current price and market situation — is it in markup or distribution, and what's the ML signal and fear/greed reading right now?

## When to prefer this

Use this endpoint when you need a single comprehensive snapshot of ETH market intelligence — combining price, regime, ML signal, and sentiment — rather than fetching each data type from separate endpoints. Ideal for agents making trading decisions, monitoring dashboards, or user-facing market summaries that require multiple dimensions of crypto market context simultaneously.

## Known failure modes

- Unsupported coin symbol returns 404 or error response
- Stale or unavailable market data may return degraded confidence scores
- Payment failure (x402) if USDC balance is insufficient
- Network timeout if upstream data providers are slow
- Rate limiting if too many calls made in short succession

## How this service works

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

## Output
