## 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 tickersfeed-stock-quote-api-9d895c47
```

Example prompt: What's the current stock price for BRK.B — give me the real-time quote with today's open, high, low, and percent change.

## When to prefer this

Use this endpoint when you need a fast, per-call stock price lookup for any US-listed equity with OHLC and percent change data, especially when cost-per-call matters (only $0.003 delayed, $0.01 real-time). Prefer this over broader financial data APIs when you only need a current quote snapshot, not historical series or fundamentals. Ideal for agents that need to check current prices on demand without a subscription.

## Known failure modes

- Unknown or invalid ticker symbol returns an error or empty result
- Symbol outside NYSE/NASDAQ/AMEX coverage (e.g. OTC, international) may not be found
- Requesting realtime tier without correct payment may return delayed data or an error
- Market closed hours may affect real-time data freshness
- Payment failure or insufficient USDC balance blocks the request

## How this service works

Stock quote for any US symbol — real-time or 15-min delayed price, OHLC, high/low, previous close, and percent change. Covers NYSE, NASDAQ, AMEX (8,400+ symbols). $0.003 USDC delayed / $0.01 USDC real-time. Add ?tier=realtime for live prices.

## Output

Returns a JSON object with the ticker symbol, quote tier (delayed or realtime), and a quote object containing current price (c), open (o), high (h), low (l), previous close (pc), and percent change (dp).
