## 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-xyz-abb597dd
```

Example prompt: What were Apple's previous-day OHLCV numbers — open, high, low, close, volume, and VWAP — for AAPL?

## When to prefer this

Use this endpoint when you need the most recent completed trading day's OHLCV bar for a single specific US equity ticker and want a simple per-call micropayment model. Prefer this over bulk daily snapshots when you only need one symbol, or over real-time endpoints when historical end-of-day data suffices.

## Known failure modes

- Invalid or unknown ticker symbol returns null data field
- Non-trading day or weekend may return null or stale data
- Payment failure (402) if USDC balance insufficient
- Rate limiting or network timeout on x402 payment protocol
- Ticker for non-US or delisted security may return null data

## 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

Returns a JSON object with the ticker symbol, source ('massive'), as_of date string, and a data object containing: open, high, low, close (all numbers), volume (number), vwap (number or null), trade_count (number or null), and timestamp (string or null) for the previous trading session. Returns null for data if no data is available.
