Question 1

Are these stock prices real-time?

Accepted Answer

Yes. PythFeeds streams US equity prices directly from Pyth Network's Hermes API, which updates every ~400ms during market hours. After-hours, the last publish time and staleness indicator tell you when the feed last updated.

Question 2

Which stocks are available?

Accepted Answer

Pyth publishes feeds for major US equities including AAPL, MSFT, NVDA, TSLA, GOOGL, AMZN, META, AMD, NFLX, COIN, SPY, QQQ and many more. The full list streams live on this page.

Question 3

How do I know if a stock price is stale?

Accepted Answer

Each feed displays a publish timestamp and a staleness pill — green if updated in the last 2 seconds, amber under 10 seconds, red beyond. During US market hours (9:30am–4:00pm ET) feeds typically show green; outside hours they go amber/red as expected.

Question 4

Can I trade stocks on PythFeeds?

Accepted Answer

No. PythFeeds is a price-data viewer only for equities. Crypto swaps on Solana are available via Jupiter on the Swap page.
