I like the fourth or the last one since it encourages all other error responses to follow a similar standard. That will allow the client to have a reusable error model and error checking.

I’ve had to use APIs where every response was 200 ok with json, 400 bad request with pain text that said unauthorized, or a 500 error that returned an HTML error page. The worst.

Instructions unclear. Baby is now a werewolf and howls loudly when Kodi is buffering.

That just allows Google full access to all logs from any application you have installed.

That service is not free either per month and those costs will be passed to the consumer in either a subscription or worse software.
