How this service works
Look up the company behind a domain: name, description, category, location, socials, mail/DNS/hosting providers and registration, each with source and confidence.
Output
A JSON company card containing: name, legal name, description, categories, kind, audience, business model, location (locality, region, country), social profiles (Twitter/X, LinkedIn, etc.), provider details (DNS, mail, hosting), domain registration info (registrar, created date, expiry, age in years, registrant org), ownership signals, per-field confidence scores, source attributions, and a list of fields not checked. Also includes a payment receipt with the settlement transaction hash.
Example use cases
Vendor due diligence before integration
“I'm about to integrate with a payments API at paymently.io — can you pull up their company card, including what kind of business they are, where they're registered, who their hosting provider is, and how confident the data is?”
Sales prospecting enrichment
“I have a lead from acmecorp.com — what can you find out about the company behind that domain? I need their description, industry category, LinkedIn profile, and location.”
Phishing domain investigation
“This suspicious email came from quickpay-secure.net — can you look up what company, if any, is behind that domain, including their registrar, how old the domain is, and who's hosting it?”
Technical details
Endpoint
POSThttps://how.is/v1/company?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, sourced company profile from a single domain name, including business metadata, social links, infrastructure providers, and registration details all in one call. Prefer this over manual WHOIS lookups, LinkedIn searches, or separate DNS queries when you want a unified, confidence-scored company card. Especially useful for sales enrichment, vendor vetting, fraud investigation, or competitive intelligence workflows.
Side effects
- Domain not found or not registered — returns empty or minimal data
- Low confidence scores when insufficient public data exists for the domain
- Domain is too new to have indexed company information
- Rate limiting or payment failure via x402 protocol
- Malformed domain input exceeding 253 characters or containing invalid characters
- Private/redacted WHOIS data limiting registrant enrichment
