## 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 agentsvc-io-stock-prices-2f8798c4 -d '<json body>'
```

Example prompt: What are the current prices for AAPL, MSFT, and NVDA — including today's change, market cap, and PE ratio?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time stock price data for up to 10 symbols per call with no API key or account setup — ideal for AI agents that need on-demand financial market data paid per use with USDC. Supports both US and international exchanges with exchange-suffix notation.

## Known failure modes

- Unrecognized ticker symbols are returned in the 'not_found' array rather than causing a request failure
- Non-US stocks require exchange suffix (e.g. .DE, .L) or the symbol may not be found
- Requesting more than 10 symbols in a single call may be rejected or only partially fulfilled
- Market data may be delayed or unavailable outside trading hours for certain exchanges
- Payment failure via x402/USDC will prevent the call from completing

## How this service works

86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.

## Output

A JSON object keyed by ticker symbol, each containing: current price, open, day high/low, 52-week high/low, previous close, price change and percent change, volume, market cap, PE ratio, currency, exchange, and market state (REGULAR/PRE/POST). Also includes a 'not_found' array for unrecognized symbols and a 'fetched_at' timestamp. Data is sourced from Yahoo Finance.
