Research direction

Open the Build an app on Base guide at the supplied Page URL and locate Step 4 and the publicnode fallback URL. Add a brief warning that it is rate-limited and intended for testing only, then verify the note appears alongside the existing production RPC warning.

Description

Description

In Step 4 of the "Build an app on Base" guide, the docs suggest using
https://base-sepolia-rpc.publicnode.com as a fallback RPC if the
default endpoint is unreachable — but no warning is given about its
limitations.

Page URL

https://docs.base.org/get-started/build-app

Problem

The page already warns about the main RPC endpoint:
"For production apps, use a dedicated RPC provider."
But this warning is absent for the publicnode fallback URL, which is also
rate-limited and unsuitable for production.

Suggested fix

Add a brief note after the publicnode fallback URL, similar to the
existing warning, clarifying it is also rate-limited and for testing only.
