Stock Price API

br0ski777/stock-price-x402

Pulls real-time stock market data through Server-Sent Events from a dedicated API endpoint. You get the basics: current price, daily change, trading volume, and market cap. Built as an x402 micropayment integration, meaning you'll pay small amounts per request rather than a subscription. The GitHub repo is pretty bare, just TypeScript source and config files, so you're looking at a straightforward quote fetcher without much documentation. Reach for this when you need Claude to check stock prices on demand and you're comfortable with usage-based pricing. No complex financial analytics or historical data, just the current snapshot.
