UpLead

UpLead is a B2B contact and company data platform providing a REST API for searching leads, verifying emails, accessing company profiles, and enriching contact information. The API enables developers to look up verified contacts by email or name, search companies by domain or name, run prospector queries to find contacts by job title or function, and perform combined person-plus-company lookups in a single call. UpLead operates on a credit-based billing model where charges only apply when verified data is returned.

UpLead publishes 8 APIs on the APIs.io network, including Account API, Combined API, Company API, and 5 more. Tagged areas include B2B, Lead Generation, Contact Data, Company Data, and Email Verification.

The UpLead catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

UpLead’s developer surface includes authentication, documentation, engineering blog, pricing, and 9 more developer resources.
