What is the Company Enrichment API?

The Company Enrichment API returns firmographics for a company from a LinkedIn company URL or domain — name, industry, size, headquarters and locations, website, funding (when available), technologies, and identifiers — as structured JSON, in one request.

How it works

Pass a LinkedIn company URL or a domain and Captain Data returns structured company data in real time, metered in credits. No scrapers, proxies, or pipelines to run.

Real-time firmographics

Company data changes — headcount, funding, tech stack, and locations move constantly. Real-time enrichment means your records reflect the company as it is now, which matters for lead scoring and account routing.

What you can build

Enrich accounts in your CRM

Fill firmographic fields on company records on demand so they don't go stale.

Score and route inbound

Enrich a domain at signup and route or score the account by size, industry, and tech.

Build account intelligence in-product

Embed live firmographics as a feature without maintaining a data pipeline.

Qualify companies for an AI agent

Give an agent structured company context (incl. via MCP) to qualify accounts.
