companies.social is an API that resolves any company identifier — a domain, Twitter handle, LinkedIn URL, or GitHub org — and returns every linked social profile for that company.

​
How it works

Pass any identifier you have, get back the full social graph: 
curl -H "x-api-key: ck_your_key" \
  https://api.companies.social/domain/stripe.com

{
  "companyId": "stripe_com",
  "domain": "stripe.com",
  "socials": {
    "twitter": "https://x.com/stripe",
    "linkedin": "https://linkedin.com/company/stripe",
    "github": "https://github.com/stripe",
    "youtube": "https://youtube.com/@stripe",
    "instagram": "https://instagram.com/stripe",
    "facebook": "https://facebook.com/StripeHQ"
  },
  "scrapedAt": "2026-03-01T12:00:00.000Z",
  "cached": true
}

Active lookups fetch and parse in real-time. Passive lookups resolve from data built by prior domain scrapes. Reverse lookup means you can query by that platform’s handle to find the company’s full social graph.
