The People Search API is HeroHunt.ai's core API product that gives developers and organizations programmatic access to our AI-powered talent search engine. It searches across 1 billion profiles on LinkedIn, GitHub, and Stack Overflow simultaneously, returning enriched candidate data with AI screening scores and verified contact details.
Instead of requiring complex boolean strings or rigid keyword filters, you can pass a full job description or a free-text query like "senior Python developer with open-source contributions in fintech" and the AI will interpret your intent, broaden or refine the search, and return intelligently matched candidates.
Each profile response includes the candidate's professional information (title, company, experience, skills, education), an AI-generated relevancy score and qualification summary, and — when data enrichment is enabled — verified professional email addresses and phone numbers.
The API searches across LinkedIn, GitHub, and Stack Overflow in a single request. This multi-channel approach is particularly powerful for technical recruitment, as it uncovers passive candidates who may not be active on LinkedIn but have a strong presence on developer platforms.
