Then, grab your API key by visiting https://rapidapi.com/certsio-certsio-default/api/certs-io1 and wait for the playground to load. Once loaded, you will see your API key in the X-RapidAPI-Key header.
certsio automatically looks for a configuration file at $HOME/.certsio.toml or %USERPROFILE%\.certsio.toml. You must specify your API key in this configuration file for the client to work.
An example configuration file can be found in the repository.
