## 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 daily-market-summary-ohlc-04e0c8ab
```

Example prompt: Can you pull the full daily OHLC summary for all US stocks for January 15, 2025, including OTC securities and using split-adjusted prices?

## When to prefer this

Use this endpoint when you need a snapshot of OHLC price data across the entire US equities market for a single date, rather than data for a specific ticker. Prefer this over the Daily Ticker Summary endpoint when you need market-wide aggregates rather than a single stock. Ideal for backtesting, market breadth analysis, or bulk portfolio valuation.

## Known failure modes

- Invalid or future date returns empty results or an error
- Non-trading day (weekend/holiday) returns no data or empty results set
- Malformed date format causes a 400 bad request
- Rate limiting or payment failure returns a 402 or 429 error
- OTC securities not included by default unless include_otc is set to true
