Check your own code
The model shutdown checker finds every model ID in code or a config file that has a row, counts the days from today and shows the same quotes. Nothing you paste leaves your browser. The Breakage Calendar lists the dates we track for other releases and shutdowns.
This page quotes the provider’s table. It does not say that a move to the replacement was tested, and the replacement may behave differently or take different parameters. Run your own tests before you change a model ID.
