How this service works

Fast, reliable network tools API. IP geolocation, DNS lookup, SSL check, WHOIS, email validation, port scan. Free tier available.

Output

A JSON object containing the company's name, description, industry, business model, size hint, technology stack, DNS and email providers, products, social profiles (including GitHub), about and contact page URLs, verified third-party services, public emails, HQ city and country, founded year, and a flag indicating whether the site contains AI instructions. Also includes which pages were analyzed and whether the result was served from cache.

Example use cases

Lead enrichment before sales outreach

“I have a prospect's domain, acme.io — can you look up what industry they're in, what size the company is, their business model, and any public contact info so I can personalize my outreach?”

Competitive tech stack research

“What technology stack and DNS/email providers is notion.so using? I want to understand their infrastructure before benchmarking us against them.”

Screening domain for AI instructions flag

“Before we index linear.app in our directory, can you check if their site contains any embedded AI instructions, and also grab their company description, products, and industry?”

Technical details

Endpoint

GEThttps://ipv4.fr/x402/v1/company/%7Bdomain%7D?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need rich, multi-dimensional company intelligence from a single domain lookup — especially when you want technology stack, DNS/email provider, industry, business model, and social profiles in one call. Prefer it over raw WHOIS or DNS lookups when you need business context rather than just technical records, and over general web scrapers when you want structured, pre-parsed company data without writing your own extraction logic.

Rate limit exceeded on free tier — HTTP 429 error
