Cheap, fast, and accurate is a rare combination in B2B data, and LeadMagic earns its place by hitting all three. It is a credit-based enrichment API that turns a person or a company into reachable details: work emails, mobile numbers, and firmographics, with real-time freshness on every call. The product is a set of focused endpoints. Email finder, mobile finder, email-to-profile, and company enrichment each return one data point per call. Emails cost a single credit, mobiles cost a few more, and unused credits roll over while you stay subscribed. Inside Clay it acts as one provider in a waterfall, filling emails and mobiles before sequences run. The API also drops neatly into pipelines built in Make or n8n. We use LeadMagic as a high-coverage, low-cost step in client enrichment waterfalls, especially for work emails and mobile numbers where its hit rate is genuinely strong. Pairing it with verification and a second provider keeps reachable rates high without inflating the cost per record. The fact that credits roll over while you stay subscribed and there is no annual contract makes it easy to scale volume up and down between client projects. On its own it needs that pairing to reach full coverage on hard lists, and being API-first, non-technical users tend to drive it through Clay rather than directly. Its firmographic depth is also thinner than a full database like Apollo.
