Price, confidence and publication time
Pyth publishers include market participants and data providers that submit observations for supported symbols. The protocol aggregates those inputs into a price and confidence interval. Applications should read both values and the publication time because a narrow-looking price without freshness checks can still be unsafe.
The feed describes a market reference under Pyth's methodology; it does not guarantee an executable trade at that value. Downstream protocols decide acceptable confidence, staleness and fallback behavior. A correct Pyth update can still be used incorrectly by an application with weak validation or unsuitable liquidation settings.
