Channel employs several bots to augment the product with extra information from around the web. We are here to help whether you found us in your access logs and you have questions or are just curious.
This bot responds to links that Channel users post into their chat rooms. It fetches as little of the page as it can (using HTTP Range headers) to extract meta tags about the content. Specifically, we are looking for Open Graph tags. If a page's tags refer to an image, video, or audio file, we will fetch that file as well to check validity and extract other metadata.
