Endpoint
GEThttps://saylorinnovations.com/api/stocks/quote/:symbol?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost real-time stock quote for a single ticker symbol and are operating in an x402 micropayment-enabled environment. It is ideal for agents that need to look up equity prices on demand without subscribing to a full-featured financial data platform.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty response
- Market closed periods may return stale or last-close data rather than real-time quotes
- Rate limiting or payment failure (x402) if USDC payment is not processed correctly
- Network timeout if upstream market data provider is unavailable
