## 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-historical-ohlcv-funding-dafa4619
```

Example prompt: Pull the last 4-hour OHLCV candles and funding rates for SOL from Carbon & Cashmere so I can review recent Solana price action and funding history.

## When to prefer this

Use this endpoint when you need historical candlestick (OHLCV) data and funding rates specifically for SOL/Solana, especially when you want professional-grade crypto market intelligence packaged with funding rate data in a single call. Prefer this over generic market data APIs when working within the Carbon & Cashmere ecosystem or when paying per-call via x402 micropayments.

## Known failure modes

- Invalid or unsupported coin symbol returns 404 or empty result
- Unsupported interval parameter returns 400 bad request
- No data available for requested time range returns empty arrays
- Payment not included or insufficient USDC triggers 402 payment required
- Rate limiting or quota exceeded returns 429

## How this service works
