## 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 xona-agent-ohlcv-candle-data-api-base-evm-a78b2b04 -d '<json body>'
```

Example prompt: Can you pull the OHLCV candlestick data for the token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base mainnet so I can analyze its recent price action?

## When to prefer this

Choose this endpoint when you need structured OHLCV candlestick data for a token on the Base/EVM network, particularly for DeFi analytics, trading signal generation, or price history visualization. It is purpose-built for Base mainnet assets and integrates with the x402 micropayment protocol, making it suitable for automated agent workflows that need per-call token price data without a subscription.

## Known failure modes

- Invalid or unrecognized token address returns an error or empty dataset
- Token not listed on supported DEX markets returns no data
- Malformed request body causes a 400 error
- Payment failure (x402) results in a 402 response and no data returned
- Rate limiting or quota exceeded may return a 429 error
