Frequently asked questions.
What is a contact enrichment API?
An API that completes a contact from one identifier: an email, a profile URL, or a name plus a company. LinkupAPI returns the current role, company, location and a verified email, and the company profile from a domain.
Which inputs are accepted?
Email address (reverse lookup), LinkedIn profile URL (full profile), first name plus last name plus company domain (email finder), and a company domain (company profile).
Is the data stored?
No. Every call is processed at request time and nothing is retained, which is why the result reflects the current role rather than an old export.
How accurate are the emails?
Each found address comes with a confidence level, and the verifier checks deliverability and catch-all domains before you send.
How is it priced?
Per action, with credits. Enriching from a CRM, a sales tool or an AI agent uses the same key and the same price.
