A read-only JSON feed of 30,000+ web hosting companies, ranked by HRI, our independent rating with no paid placements. Build landing pages, comparison tools, or research on data you can actually trust, then attribute and link back.
Every list is ordered by HRI, built from verified reviews, completeness, freshness and performance. No company pays for position.
Clean JSON, CORS open, CDN-cached one day. Fetch it server-side at build time and ship the data as static, indexable HTML.
Free for most editorial use in exchange for attribution and a dofollow link to hostlist.io. Tell us about commercial or high-volume use.

}Category queries share the same definitions and HRI order as the public category pages and return up to 120 hosts. Enumerate every category, country, and segment at /api/v1/vocabulary, or load category pool sizes from /api/v1/categories.
One endpoint, https://hostlist.io/api/mcp, over Streamable HTTP. Nothing to install, no local process, no key to paste. Point a client at it and five tools appear.

}Anonymous and read-only. An agent can query the directory the moment it connects. Nothing to request, nothing to rotate, no token in your transcript.
Every tool reads. None of them writes, and there is no tool that edits a listing. Hosts update their own profile in the dashboard after claiming it, never through this endpoint.
find_hostsSearch active hosting companies by name, country or segment. HRI order.get_hostEverything public about one company: HRI and its four components, location, founding year, ratings.compare_hostsTwo to five companies side by side on the same fields.explain_hriThe current HRI version, its four pillars, and the ranking policy.directory_activityThe latest dated changes to the directory.The public endpoints are open. Use this form if you want a private key, guaranteed throughput, a custom dataset, or you are planning commercial use. We answer most requests within two working days.
The data is free to use for most non-commercial and editorial use cases, in exchange for clear attribution and a dofollow link back to hostlist.io. High-volume or commercial use may have terms; tell us your use case and we will confirm.
Each host returns its name, HRI (and the trust, completeness, freshness and performance sub-scores), segment, country and city, founded year, logo, website, review ratings, and its hostlist.io profile URL. Lists are ranked by HRI, never by payment.
Responses are cached for one day and reflect the latest HRI run. Rankings update as new reviews, performance signals and profile data come in. Fetch at build time and rebuild daily to stay current.
Yes, that is exactly what it is for. Fetch it server-side at build time and render the data as static HTML. Keep your own editorial angle rather than copying full tables, attribute HostList, and link back with a dofollow link.
Not by default, the public endpoints are open and CDN-cached. If your use case needs guaranteed throughput or a private key, request one through the form on this page.
