The Crustdata API finds, enriches and monitors people and companies, and searches job postings, social posts and the web. It combines 15+ sources into one record per person or company. Some endpoints are add-ons or in beta; Permissions shows which ones your account can call.

​
Build a prospect list from a description of your customer

Describe the accounts and people you want in plain English or with structured filters. Company Search finds the accounts by industry, headcount, funding, location and tech stack. People Search finds the decision-makers inside them by title, seniority and function. Contact Enrichment then returns business emails, personal emails and phone numbers for the people you keep. Endpoints: Company Search API, People Search API, Semantic People Search API (beta), Contact Enrichment API

Source candidates for a recruiting product

Search people by role, skills, location, employer and education, and get each profile back with full work history including start and end dates. Job Title Normalization maps raw job titles to a standard taxonomy so you can rank candidates consistently. Endpoints: People Search API, Job Title Normalization

​
Enrich records you already have

Person Enrichment turns a profile URL into the full person record. Reverse Email Lookup resolves an email address, business or personal, to the person behind it. Company Identify matches a company name, domain or profile URL to a Crustdata company, which Company Enrichment expands into a full profile. On enterprise plans, Batch Person and Company Enrichment take up to 10,000 records per job and deliver the results as a file.
