NzbNDX is a Usenet search engine that provides an index of what is in some newsgroups. It is an automated indexer based on Newznab.
Launched in 2013, NzbNDX is used to search for content and download NZB files or to make API calls. They have over 1.8 million NZBs indexed and are growing by the day. Invites are not required by this site, and free account users can enjoy a limited number of APIs and NZBs for a period of two weeks.
While invites are not required, registration is necessary to be able to access the NzbNDX main site. Forum is available to all users, and the site runs on SSL encryption to assure privacy and security of its users. For an increased number of NZB downloads and APIs, you can subscribe to their VIP account which also allows you to integrate their engine with software like Sickbeard, SabNZBD, CouchPotato or RSS.
NzbNDX only has 2 primary membership levels: Free and Donator. They vary in NZB downloads per day and API calls. Free membership lasts for only 2 weeks. You can join as a donator or VIP level member by paying via PayPal.
NzbNDX has 300 days of retention, which is lower than the average retention rate of most NZB sites. They have approximately 30 newsgroups crawled.
The NzbNDX website is built on Newznab, which is a popular indexing platform used by top NZB sites. This makes the site easy to use and navigate where you can easily search their NZB index and allows keyword search inside categories. Search results are broken down according to name of post, category, date of post, file size, number of files and member comments.
Their uptime average is at 98% and response time is approximately 1700 milliseconds. Their indexer runs every 15 minutes. However, other technical information like hardware details are not disclosed.
Aside from limitation on NZB downloads and API call, NzbNDX free account is also limited on the duration of use. Free accounts can only be used for 2 weeks. After the said period, you can pay a fee of $12 to get the full features of being a VIP member. Their VIP features are certainly competitive with other NZB sites, so NzbNDX is definitely a service that Usenet users should consider.
