What you can build

## One API. Every signal you need.

The same data and algorithms that power the Ocean product — search, enrichment, and lookalike scoring — as simple REST endpoints.

### Search

Filter a database of 85M+ companies by industry, technology, headcount, location, and growth signals — Boolean, fuzzy, or semantic AI search.

### Enrich

Pass a domain or email. Get back a full structured profile in milliseconds — no batch jobs, no cold starts.

### Lookalikes

Given any company, return the closest matches in the database ranked by our context-vector similarity model.

### Email reveal

Pass a LinkedIn URL and get back a verified email address, confidence score, and full person profile.

POST /v1/companies/search
