Yolodex

What is Yolodex?

Yolodex is an open-source email enrichment API that helps developers build comprehensive customer profiles from email addresses. By submitting an email, the API returns structured data including name, country, age, occupation, company, social media handles, and interests—all aggregated from publicly available sources and returned in JSON format. The tool serves developers and businesses looking to enhance customer data for CRM systems, marketing personalization, and audience segmentation. Rather than maintaining separate data sources, teams can use a single API call to populate customer information automatically. The API follows a straightforward REST design, making integration into existing workflows straightforward. Yolodex offers a transparent pricing model with 100 free credits provided to new users, allowing developers to test functionality before scaling usage. As an open-source project, the codebase is available for review and contribution. Yolodex is particularly useful for teams building customer intelligence features, conducting lead research, or enriching existing databases with demographic and professional information. The focus on publicly sourced data means lookups rely on information already available online rather than private databases, which aligns with transparency and data privacy considerations.
