The Gist API provides up to one megabyte of content for each file in the gist. Each file returned for a gist through the API has a key called `truncated`. If `truncated` is `true`, the file is too large and only a portion of the contents were returned in `content`.

In addition to a specific file's contents being truncated, the entire files list may be trucated if the total number exceeds 300 files. If the top level `truncated` key is `true`, only the first 300 files have been returned in the files list. If you need to fetch all of the gist's files, you'll need to clone the gist via the URL provided by `git_pull_url`.
