"PaLM" (Service Connection)

This service is obsolete as of Version 14.1 (2024). The underlying API was officially discontinued by Google in October 2024. Use "GoogleGemini" instead.
Use the PaLM API with the Wolfram Language.

Connecting & Authenticating

ServiceConnect["PaLM"] creates a connection to the PaLM API. If a previously saved connection can be found, it will be used; otherwise, a new authentication request will be launched.
Use of this connection requires internet access and a Google account.
