How this service works
Company identity & website facts from a domain: legal name, VAT/SIREN and registered address when published, contact page URL, company social pages, tech stack, SEO/security audit signals. Obeys robots.txt; no personal data, no emails or phone numbers. Unbilled on errors.
Output
A JSON object containing the company's legal name, domain, social media URLs (X, LinkedIn), contact page URL, registered address (if publicly published), company identifiers (VAT/SIREN), list of pages read, technologies detected (name, version, category), audit signals (HTTPS, HSTS, sitemap, H1 count, title length, page weight, issues list), robots.txt compliance flag, and a fetch timestamp. Returns status 'ok' on success; unbilled on errors.
Example use cases
B2B lead enrichment from domain
“I have a lead's website domain — stripe.com — can you pull their legal company name, SIREN or VAT number, registered address if published, LinkedIn page, and tell me what technologies their site runs on?”
Security and SEO pre-check before partnership
“Before we sign a deal with this vendor at notion.so, can you run a quick audit on their domain and tell me if they have HTTPS, HSTS, a sitemap, and any obvious SEO problems?”
Competitor tech stack reconnaissance
“What tech stack and analytics tools is linear.app using on their website, and do they have any security issues like missing HSTS or an oversized page?”
Technical details
Endpoint
GEThttps://audit-site-web.pga-agent.fr/api/company-from-domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to enrich a company record from just its domain name — especially for European companies where VAT/SIREN numbers may be published on imprint/legal pages. It is preferable over generic web scrapers because it is purpose-built for company identity extraction, respects robots.txt, returns no personal data (no emails or phone numbers), and combines business identity with tech stack and SEO/security audit signals in a single call. Use it for B2B lead enrichment, vendor due diligence, or competitive intelligence workflows.
Side effects
- Domain not found or unreachable — no data returned, call unbilled
- robots.txt disallows crawling — endpoint respects it and may return partial or no data
- Company does not publish legal/VAT information on its site — company_ids and address fields return empty or null
- Domain resolves but has no meaningful company content — sparse results
- Rate limiting or network timeouts on the target domain — call may fail and be unbilled
