## When to prefer this

Choose this endpoint when you need a cryptographically auditable stock quote — ideal for AI agents operating in regulated or compliance-sensitive contexts where you need a verifiable chain of data provenance. Particularly useful when integrating stock price lookups into automated workflows across 27 countries, or when you need a consistent REST/MCP/A2A interface for financial data without managing a separate brokerage API integration.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error
- Market is closed and no real-time price is available (may return last close)
- Network timeout or upstream data provider outage
- Missing required 'symbol' query parameter returns a validation error
- Payment failure via x402 micropayment protocol

## How this service works

## Output

Returns a real-time stock quote for the requested ticker symbol, including current price and related market data. Every response includes a cryptographic audit record with chain hashing for verifiability and compliance purposes.
