from $0.60 / 1,000 company resolveds
Turn a list of company names into official websites and social profiles, with a confidence score, the signals that fired, and the rejected candidates and why. Directory and profile hosts are never returned as a company website.
query
Optional
The entry exactly as it was supplied, so a row can be lined back up with the input list.
companyName
Optional
The company name that was looked up, after any surrounding whitespace was trimmed.
domain
Optional
The registrable domain judged to be the company's own website, without a protocol or www.
websiteUrl
Optional
The homepage URL that was fetched and scored, after any redirects were followed.
confidence
Optional
How strongly the evidence supports this domain belonging to this company, from 0 to 1.
matchedOn
Optional
The signals that fired for the winning domain, such as registry-match or name-is-domain.
[ "registry-match", "name-is-domain", "exact-name-in-title"]homepageVerified
Optional
Whether the returned domain's own homepage was fetched and read. False means the domain rests on a registry claim or the name alone, which is a lead rather than a confirmation.
resolvedTitle
Optional
The title tag of the homepage that was matched, useful for eyeballing a low confidence row.
description
Optional
The meta description or Open Graph description the homepage publishes about itself.
logoUrl
Optional
The Open Graph image or touch icon the homepage declares, resolved to an absolute URL.
country
Optional
ISO 3166 alpha-2 code, taken from the request where one was given and otherwise inferred from the domain ending.
registeredAt
Optional
When the domain was first registered, from RDAP. Registrant identity is redacted by every major registry but the date is not.
domainAgeDays
Optional
Whole days since the domain was registered. A very young domain is penalised when scoring, because a company asked for by name is rarely three weeks old.
nameServers
Optional
Nameservers the domain resolves through, lowercased and sorted. Useful for spotting group companies that run one domain per market off shared infrastructure.
[ "ns-1.example-dns.com", "ns-2.example-dns.co.uk"]registrar
Optional
The registrar holding the domain, which is the only party RDAP still names. Not the owner.
alternates
Optional
Candidate domains that were not returned, each with its score and the reason it lost.
[ { "domain": "linkedin.com", "confidence": 0, "reason": "directory, registry or social profile host, never a company website" }, { "domain": "example.co.uk", "confidence": 0.35, "reason": "scored 0.35 against 0.82 for example.com" }]status
Optional
found when one domain won clearly and its homepage was read, ambiguous when the winner is close or unconfirmed, not_found when every source answered and no candidate survived, unavailable when a source could not be reached at all.
checkedAt
Optional
When the lookup ran, ISO 8601, so a cached row can be aged out.
error
Optional
Why a row without a confirmed answer is worth running again, naming the source that did not answer or the homepage that did not respond. Null on a confirmed row.
socials
Optional
Social profile URLs read from the company's own homepage markup, null where the homepage links to none.
