## 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 market-data-previous-close-ohlc-x402atlas-f133ec15
```

Example prompt: What was AAPL's open, high, low, close, and volume from the previous trading day? Pull the previous-close OHLC bar for the stock ticker AAPL.

## When to prefer this

Use this endpoint when you need a quick, single-record summary of where an asset ended the most recent trading session — ideal for daily portfolio snapshots, morning briefings, overnight move detection, or seeding technical indicators. Prefer this over full historical bar endpoints when you only need the last completed session, not a time series.

## Known failure modes

- Invalid or unknown ticker returns a 404 or empty result
- Market holidays or weekends may shift the 'previous day' back further than expected
- Crypto tickers missing the X: prefix may return no results
- Network or payment errors (402 payment required if USDC payment fails)
- Malformed ticker prefix returns an error response

## How this service works

Previous trading day OHLC bar for stocks, crypto, forex and options — yesterday's open/high/low/close and volume by ticker.

## Output

A single OHLC record for the prior trading day containing the open, high, low, and close prices plus volume, date, and the vwap for the requested ticker. Crypto uses the X: prefix (e.g. X:BTCUSD), forex uses C: (e.g. C:EURUSD), stocks use bare tickers.
