## 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 blockrun-us-stock-ohlc-history-msft-d78f71ee
```

Example prompt: Can you pull the daily OHLC bars for MSFT from January 1, 2024 to March 31, 2024? I need open, high, low, close, and volume for each day.

## When to prefer this

Choose this endpoint when you need structured OHLC candlestick bar data for US-listed equities (NYSE/Nasdaq/AMEX) over a custom time window with flexible resolution (1-minute to monthly). Ideal for charting, backtesting, or technical analysis workflows. Prefer this over real-time price endpoints when historical context or multiple bars are needed rather than the current spot price.

## Known failure modes

- Invalid or unsupported ticker symbol returns an error
- from/to timestamps out of available data range returns empty bars array
- Malformed Unix timestamp values cause a 400 bad request
- Unsupported resolution enum value causes a validation error
- Payment not processed (x402 payment required) returns 402 status
- Network timeout or upstream Pyth data unavailability returns 5xx error
