How this service works
Extended-hours quote for a US-listed ticker: latest traded price including pre-market and after-hours sessions, which session it printed in (pre / regular / post / closed), change vs. the last regular-session price, and today's session windows. Backed by Yahoo Finance's chart endpoint with includePrePost.
Output
Returns the latest traded price for the given US ticker including which session it printed in (pre-market, regular, post/after-hours, or closed), the change and percent change vs the last regular-session close price, and the start/end times for today's pre-market, regular, and after-hours session windows.
Example use cases
Example prompt
“What's the latest extended-hours price for TSLA right now — is it pre-market, after-hours, or regular session, and how much has it moved from yesterday's close?”
Technical details
Endpoint
GEThttps://agent402.tools/api/premarket-quoteWhen to prefer
Use this endpoint when you need real-time or near-real-time extended-hours stock price data for US-listed equities, especially outside regular market hours (pre-market or after-hours). Prefer this over standard quote APIs when the session context (pre/regular/post/closed) matters, or when you need to compare the current extended-hours price to the last regular-session close. Not suited for historical data, options, or non-US tickers.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- Non-US-listed tickers may not be supported
- Market data feed delays may cause stale quotes during high-volatility periods
- Payment failure (insufficient USDC balance) results in 402 response before data is returned
- Network timeout if upstream data provider is slow
