Why? I want to check the url is submitted or not by HN in chrome extension, but don't want to call HN Search API (https://hn.algolia.com) every time for security issue.

Result? 10 year links in HN count is about 2143436, total bloom filter size 2143436 * 2B, file size ~ 5M. Find building status in https://hackernewsfilter.com/status/ . The bloom filter factors can be found in https://hackernewsfilter.com/faq/#check .

Product? The chrome extension based on these data can be find in https://hackernewsfilter.com/ , after install, you can check if an url is submitted or not when every time you open a link.

Enjoy!
