## How to call it through Zero

```sh
zero fetch --capability onesource-deepstate-ohlcv-candles-50180eeb
```

Example prompt: Can you pull the 1-hour OHLCV candles for the ETH-USDC book from OneSource Deepstate, covering the last 7 days?

## When to prefer this

Use this endpoint when you need structured OHLCV candlestick data for a specific market book on the OneSource Deepstate platform, especially for DeFi/DEX markets that may not appear on centralized exchange APIs. Prefer this over generic market data providers when you need raw on-chain price data with trade counts, market session context, and token contract metadata bundled alongside candles. Ideal for agents doing technical analysis, backtesting, or real-time signal detection on decentralized markets.

## Known failure modes

- Invalid or unknown book identifier returns an error or empty response
- Missing required 'tf' (timeframe) query parameter causes a 400 error
- Invalid timeframe value outside the allowed enum causes a 400 error
- Invalid 'from' or 'to' timestamp format may cause parsing errors
- No candles available for the requested time range returns an empty candles array
- Payment failure or insufficient USDC balance (x402) prevents the request from completing

## Output
