Company Domain Lookup

Company name to domain API

Resolve company names to likely official domains with explainable reasons, confidence from 1-100 when found or 0 for a completed no-match, and nullable reachability.

Short answer: use Company Domain Lookup to find a company domain from a company name. Found matches always include confidence from 1-100, completed no-match outcomes return 0, and errors include no confidence score. Use that contract to decide whether CRM automation should write, review, or hold the result.

Input

Company name plus context

Company name and optional context such as location, industry, or keywords.

Output

Official domain candidate

Likely official domain with confidence from 1-100 when found, confidence 0 for a completed no-match, nullable is_live, explainable match reasons, and cached-result status. Errors include no confidence score.

Nullable LinkedIn URL, industry, sub-industry, and sector fields are included when available.

Review path

Auto-accept or review

Accept high-confidence matches or review when confidence is lower.

Boundary

Company identity, not people

Company domain finder for submitted company names. Not a WHOIS API. Not a domain availability checker. Not an email-finding API.

How teams run lookup

API automation or dashboard lookup

Use the API when domain resolution belongs in code. After sign-in, enter one company name in the dashboard's Find Domain form for a one-off lookup, or import a list for bulk processing and review. The one-company lookup runs in the background, the page updates automatically, and you can leave and return before its five-minute processing window ends. Transient service failures are retried within that window.

API automation

Resolve domains before systems write

Call the lookup endpoint from CRM imports, onboarding flows, or scheduled jobs before dedupe, enrichment, routing, and reporting use the record.

Dashboard workflow

Find one domain or process a list

Use Find Domain for one company without keeping the page open, or process imported records and review confidence signals before CRM automation writes, reviews, or holds a result.

What you get

Accurate domain matches you can trust and act on.

Capability What it returns How teams use it
Confidence scoring Found matches return 1-100; completed no-match outcomes return 0. Errors include no confidence score. Set policies for auto-accept, review, or no match.
Explainable reasons See why the domain was matched. Official website match, name similarity, context match, and more.
Domain reachability See whether the domain appeared reachable when evaluated. Check cached before treating reachability as fresh.
Optional company context Nullable LinkedIn URL, industry, sub-industry, and sector fields. Reuse provider context when it is returned.
Review bands Use documented high, medium, low-match, and no-match bands. Bulk processing auto-verifies scores of 85 or higher; keep lower scores in review.
CRM matching ready Clean, normalized domain output. Easy to dedupe, enrich, and merge.

Confidence policy example

Confidence Action Typical use
High (85-100) Auto-accept Use when context matches
Medium (60-84) Review Verify before routing
Low match (1-59) Investigate Keep unchanged when uncertain
No match (0) Hold Keep the domain blank

Match-confidence policy

Treat confidence as a routing signal, not as permission to overwrite trusted CRM fields on every row. High-confidence live matches can feed low-risk fields, while found-match scores from 1-59 should preserve the source name and move to review. Confidence 0 means no match and the domain should stay blank; errors include no confidence score.

CRM mapping: company name, domain, confidence, reasons, live-domain status, and optional LinkedIn or industry context.

How we scope domain lookup claims

Domain Lookup claims are grounded in the public API contract, match-confidence guidance, and the benchmark-methodology page. Keep reviewer decisions tied to the returned confidence, reasons, is_live, and cached status instead of treating every match as an automatic CRM overwrite.

Frequently asked questions

Common questions about resolving company names to likely official domains before enrichment, routing, and CRM cleanup.

What does the Company Domain Lookup API return?

A found match returns the most likely official company domain, explainable reasons, and confidence from 1-100. A completed no-match returns confidence 0, while errors include no confidence score. Reachability remains nullable; check cached before treating it as fresh.

Is this a WHOIS, domain availability, or email-finding API?

No. Elvesora Company Domain Lookup resolves company names to likely official website domains. It is built for CRM cleanup, enrichment preparation, deduplication, and routing workflows, not for WHOIS lookup, domain registration availability, or email finding.

When should domain lookup run in a workflow?

Run domain lookup before enrichment, dedupe, routing, or account ownership logic so downstream systems use the reviewed company domain instead of a messy name string.

How does confidence scoring help teams review matches?

Confidence scoring gives teams a practical signal for whether a match can be automated or should be reviewed before it updates CRM or enrichment data.

Can Elvesora identify company leadership from a domain?

No. Elvesora focuses on company-level data enrichment: business domains, firmographics, company descriptions, industry, headquarters, and CRM-ready company records. It does not provide executive profiles, private contact data, or leadership email lists.
