How this service works
Company contact details as published by the company on its own website: shared emails only (contact@, press@, dpo@; personal addresses never returned), phones in E.164, head-office address, social pages, contact form, and legal identifiers checked (SIREN Luhn, VAT checksum, RCS, Impressum register) and matched to the French registry. Every field sourced. From a domain or URL. Nothing found = not charged.
Output
A structured record of the company's publicly-published contact information as found on their own website, including: shared functional email addresses (e.g. contact@, press@, dpo@) but never personal addresses; phone numbers in E.164 format; head-office postal address; links to social media pages; contact form URL; and verified legal identifiers (SIREN with Luhn check, VAT checksum, RCS, Impressum) matched against the French registry. Every field includes its source. If nothing is found, no charge is made.
Example use cases
B2B outreach contact lookup
“I need to reach out to alan.com — can you find their official shared contact emails (like contact@ or press@), phone number, and head-office address from their website?”
GDPR DPO contact discovery
“We need to send a GDPR data subject request to leboncoin.fr — can you find their DPO email address and any relevant legal identifiers like their SIREN number?”
Supplier due diligence pre-onboarding
“Before we onboard a new supplier at qonto.com, can you grab their official contact details, verify their SIREN and VAT numbers against the French registry, and get their registered office address?”
Technical details
Endpoint
GEThttps://resolve402.dev/api/company-contacts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract official, publicly-published company contact details from a company's own website — especially for French companies where SIREN/VAT/RCS verification against the national registry adds trust. It is preferable over generic web scrapers because it specifically filters out personal email addresses, normalises phone numbers to E.164, and validates legal identifiers with checksums. Use it for B2B outreach, GDPR compliance (DPO contact), supplier onboarding, or any workflow needing verified, sourced company contact data. The pay-per-result model (not charged if nothing found) makes it low-risk.
Side effects
- Domain has no publicly-listed contact information — returns empty result, no charge
- Domain is unreachable or does not exist — returns error
- Company is not French or not in the French registry — legal identifiers may be absent or unmatched
- Only personal email addresses found — none returned by design
- Rate limit exceeded — HTTP 429
- Invalid domain or URL format — HTTP 400 bad input
