## 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-syraa-fun-0ee1b2f7
```

Example prompt: Give me the current trading signal for Solana using 1-hour candles on Binance — is it a buy or sell right now?

## When to prefer this

Use this endpoint when you need algorithmic, real-time trading signals derived from OHLC candlestick data across major CEXs (Binance, Coinbase, OKX, Bybit, Kraken, KuCoin, Bitget, Upbit, Crypto.com) or CoinGecko. Prefer this over raw price endpoints when you want a computed buy/sell/hold recommendation rather than raw market data. Especially useful when CEX APIs are blocked and you need CoinGecko as a fallback source.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or unsupported instId for the selected source exchange — returns 400 or empty signal
- Exchange API temporarily unavailable — may return error or stale signal
- Invalid bar/interval value not supported by the exchange — returns 400
- Rate limit exceeded on upstream exchange data — returns 500 or timeout
