## 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 sitecheck-crypto-finance-iex-cloud-public-stock-quote-2c15956f
```

Example prompt: What's the current stock price for AAPL, including the bid, ask, and whether the market is in pre-market or regular session right now?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time US equity, ETF, or index quotes with rich metadata (bid/ask, volume, 52-week range, earnings date, market status) and no API key or signup. Ideal for pay-per-call agent workflows where you only pay $0.002 USDC when data is successfully returned. Prefer over subscription-based data providers for low-frequency, on-demand lookups.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty result
- Non-US tickers are not supported
- Market data may be delayed or unavailable outside US market hours for certain asset classes
- Missing required 'symbol' query parameter causes request failure
- Incorrect 'assetClass' value may return mismatched or empty data

## How this service works

Real-time US stock, ETF or index quote (replacement for the closed IEX Cloud public quote): company name, exchange, last sale price, net and % change, bid/ask price and size, volume, last trade time, market status (pre-market, open, after-hours, closed) with the regular-session close, day high/low, 52-week range and upcoming earnings date. Data from Nasdaq.com's public quote API.

## Output

Returns a JSON object with the ticker symbol, company name, asset class, exchange, current quote (bid, ask, last price, change, change percent, volume, real-time flag, last trade timestamp), regular session close data, 52-week range, market status (Pre-Market / Regular / After-Hours), next earnings date, and a source URL pointing to NASDAQ's market activity page.
