+  ids](https://pyth.network/developers/price-feed-ids) page to look up the id
+  for a given symbol. The returned price and confidence are decimal numbers
+  written in the form `a * 10^e`, where `e` is an exponent included in the
+  result. For example, a price of 1234 with an exponent of -2 represents the
+  number 12.34. The result also includes a `timestamp` which is the unix
+  timestamp for the price update. The EMA methodology is described in more
+  detail in this [blog
+  post](https://pythnetwork.medium.com/whats-in-a-name-302a03e6c3e1). The caller
+  provides a `max_age_secs` argument that specifies how old the price can be.
+  The call reverts if the on-chain price is from more than `max_age_secs`
+  seconds in the past (with respect to the current on-chain timestamp). Users of
+  this method will typically invoke [update_price_feeds](update-price-feeds) to
+  update the on-chain price before reading it. This step ensures that the
+  on-chain price is fresh and the call does not revert.
