## 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 x402stock-previous-close-bar-9e62a821
```

Example prompt: What was the open, high, low, close, volume, and VWAP for AAPL on its most recent completed trading day?

## When to prefer this

Use this endpoint when you need a quick prior-close reference for a single ticker without specifying a date range. It is ideal for agents that need end-of-day context (close price, VWAP, volume) as a baseline before market open or for portfolio snapshots. Prefer it over range-based endpoints when only the last completed bar matters and you want minimal payload and cost ($0.01 USDC per call). No API key setup required — payment is handled seamlessly via x402 USDC.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Non-trading days (weekends, holidays) may affect which session is returned as 'most recent'
- Payment failure via x402/USDC will block the response
- Delisted or OTC tickers may not be supported
- Rate limits or upstream data provider outages could cause temporary failures

## How this service works

Open, high, low, close, volume, and VWAP for a ticker's most recent completed trading day. One call returns one bar, handy for prior-close reference without setting a date range. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

## Output

A single OHLCV+VWAP price bar for the requested ticker covering its most recently completed trading session, including open, high, low, close prices, total volume traded, and volume-weighted average price (VWAP), along with the date of the session.
