Open the original- What it measures
- The package uses this key when you call recognize_google without a key argument, so a script can stop working without any change to your own code.
- What it does not show
- The docstring is the package's own warning. It does not give a date, a rate limit or a price, and Google does not publish terms for this unofficial endpoint on the page.
