## 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 agent-newsstand-tokenized-asset-ohlcv-candles-78826138
```

Example prompt: Pull the last 30 days of daily candles for xyz:GOLD so I can see its recent price trend.

## When to prefer this

Choose this endpoint when you need historical OHLCV candlestick data specifically for tokenized real-world assets or on-chain venue-traded tokens, and you want pay-per-call access with no API key or subscription required. It is distinct from traditional equity data providers because it focuses on tokenized asset venues and uses USDC micropayments via x402.

## Known failure modes

- Invalid or unrecognized venue symbol returns an error or empty dataset
- Requested days value outside 1–90 range rejected by schema validation
- Payment not received or insufficient USDC balance causes 402 response
- Symbol format not matching 'venue:TICKER' pattern may result in lookup failure
- Service temporarily unavailable returns 5xx error
