Introduction

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
}

Supported platforms

Platform	Lookup by domain	Reverse lookup
Twitter	Active	Passive
LinkedIn	Active	Active
GitHub	Active	Active
YouTube	Active	Active
TikTok	Active	Active
Instagram	Active	Passive
Facebook	Active	Passive

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.
