## When to prefer this

Choose this endpoint when you need a real-time or after-hours market quote for a listed security and want a paid, agent-optimized API with low latency. Particularly useful for agents operating outside standard market hours who need after-hours pricing, or when integrating into a financial workflow that already uses StableJack's broader research API suite.

## Known failure modes

- Invalid or unrecognized symbol returns an error or empty result
- Missing required 'endpoint' or 'symbol' parameter causes a bad request response
- After-hours data unavailable for certain symbols or exchanges
- Rate limiting or payment failure (x402 USDC payment not processed) blocks the request
- Market closed periods may return stale or null quote data for some instruments

## Output

Returns a current or after-hours market quote for the requested symbol, typically including price, bid/ask, volume, and timestamp metadata as provided by StableJack's research API.
