## 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-sol-network-stats-8bcca020
```

Example prompt: Can you pull the latest Solana network stats from Carbon & Cashmere — I want to see the current SOL hashrate, block count, and difficulty right now?

## When to prefer this

Use this endpoint when you need live Solana-specific network-layer metrics (hashrate, difficulty, block count, DAG tips) rather than price or trading signals. Prefer this over general market endpoints when the use case is blockchain health monitoring or on-chain analytics for SOL.

## Known failure modes

- Unsupported coin ticker returns 404 or empty response
- Network timeout if blockchain data source is temporarily unavailable
- Payment failure if x402 USDC payment of $0.02 is not included or invalid
- Rate limiting if too many requests are made in a short window
