FAQ
Frequently Asked Questions
Can't find the answers to your questions? Reach out to us by clicking here.
What counts as B2B people data?
Structured professional information about individuals in a work context: name, current title, company, work history, education, skills, seniority, industry, and location. Reverse Contact returns all of these through the people data API in a single verified profile.
Which fields does your people data API return?
Identity, professional history, education, skills, languages, location, industry, seniority, social signals, and metadata like last-updated timestamps and confidence scores. Full schema in the Documentation.
How do you handle uncertain matches?
We return null instead of a best guess. Every response includes a confidence score so your product decides what to do with borderline matches. You can also raise the precision threshold in your request.
How fresh is the data?
Retrieve profiles live on demand for maximum freshness, or pull from our database for lower latency. Every response includes a last-updated timestamp.
How is this different from a reverse email lookup tool?
Lookup tools return a name and maybe a title. Our people data API returns a full structured B2B profile per person: identity, professional history, education, skills, location, and more, built to be embedded in products and workflows.
Is Reverse Contact compliant with GDPR and CCPA?
Yes. Compliance is built into how we collect and process data. Full documentation in the Trust Center.
