A simple Go client for the Danbooru API to download images in a batch. Currently maxed out at 2 tags per search, however if you are Danbooru Gold member then this limit gets increased to 6.

To take advantage of that, rename the .env.example file to .env and enter the required credentials.

Just make sure you keep said .env file in the same directory as the executable.

This tool tends to not do so well when you're trying to download an extreme amount of images (97k+), as at some point it always starts to receive HTTP 500 responses from the server. This can be partially mitigated by increasing the rate limit applied when fetching all posts.

I found that even when fetching 1 page per second it will still error out well before hitting the end. This is obviously much better than having it error out before even hitting more than a couple hundred pages but you also have to deal with a cripplingly slow process of fetching posts.
