Free tierNo account and no key. GET /search/?q=linux returned 54,006 bytes with a rendered result list, and GET /nzb:<details-id>/ returned a 7,231-byte NZB with 19 files. No daily counter is published on the site.
unit unlimited; metered on none; No quota page exists; the claim rests on a 5-request burst rather than a vendor sentence.

Limits
  • request-rate none observed: 5 consecutive anonymous searches in one session, all 200
No request counter, byte counter or per-IP shaping was observed.
Bindingnone Nothing in the vocabulary fails at 1 TiB/month. The practical ceiling is index coverage per newsgroup, which is not a limit kind.
Identityanonymous No account and no key: search and NZB download both answered an anonymous request.
EgressNo metering. The result page and the NZB are both kilobytes; the payload comes from the news provider.
Per-object capnot applicable: the answer is an NZB pointer file (7,231 bytes, 19 files), never the payload
Retentionnot stated on the pages read. A third-party indexer comparison claims '4,000+ days retention, 200 million+ Usenet posts indexed, 3,570 newsgroups' (nzbhydra.com, 2026-10-23).
Interfacerest HTML search over HTTP GET against /search/?q=<query>. Each result carries a /details:<id>/ link and an NZB link served as /nzb:<id>/. Both are plain GETs.
ToolingNo Newznab API found, so Prowlarr and NZBHydra2 cannot add it. A wrapper parses /search and GETs /nzb:<id>/, and the site also offers a per-query RSS feed (the page advertises 'Get query as RSS feed'), which is the cheaper automation route.
Composes withA third unnamed fallback that also exposes an RSS feed per query, so a cron job can watch a name without a scraper.
ReliabilityThe result page loads a cookie-consent script and an analytics tag before results; the results themselves are server-rendered, so a plain GET still sees them.
Evidence notemeasured Search and download were run today with status, bytes and digest. A per-query RSS feed is advertised in the page text but was not fetched, so the feed route is documented-by-advertisement only.
