What is the People Enrichment API?

The People Enrichment API returns a complete professional profile from a single LinkedIn profile URL — name, headline, current role and company, location, work experience, education, skills, and LinkedIn identifiers — as structured JSON. Instead of scraping profiles or maintaining a data pipeline, you make one request and get clean, ready-to-use data you can ship in a product, workflow, or AI agent.

How it works

Send a LinkedIn profile URL to the endpoint; Captain Data handles collection, rate limits, and parsing, returning structured JSON in real time — usually within a few seconds. Usage is metered in credits (most enrichments cost one credit), so it scales from a single lookup to high-volume, programmatic enrichment. No proxies, sessions, or scrapers to run.

Real-time enrichment vs a cached database

Professional data decays fast — people change roles, companies, and locations constantly. Because Captain Data enriches in real time on each request, the data reflects the profile as it is now, not a snapshot from a dataset's last refresh. That freshness is what makes enrichment reliable for lead scoring, routing, and AI agents that act on the result.

What you can build

Enrich on signup

Turn a new signup into a full profile the moment they register — personalize onboarding and route leads in real time.

Power an AI SDR or agent

Give agents fresh, structured profile data (including via MCP) so they qualify and personalize with current information.

Keep your CRM current

Refresh contact and company fields on demand so records don't go stale between manual updates.

Build enrichment into your product

Embed real-time people data as a feature without building or maintaining a data pipeline.
