What is the People Search API?
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.
How does the natural language search work?
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.
What data does the API return for each profile?
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.
Which platforms does the API search across?
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.
Is there a free tier or trial available?
Yes. HeroHunt.ai offers a free trial so you can test the API with real queries before committing. There is also a free tier for small usage that is suitable for startups and testing integrations. Paid plans offer flat-rate monthly pricing with higher volumes.
How fresh is the data?
All data is fetched in real time. Unlike many competitors that rely on cached databases that can be weeks or months out of date, every People Search API request retrieves the freshest profile information available at that moment.
What about GDPR and compliance?
HeroHunt.ai only provides publicly available information and places a strong emphasis on compliance. The API is designed for professional outreach purposes (recruiting, business development). Users are responsible for ensuring they use contact data in accordance with anti-spam regulations and GDPR requirements when contacting candidates in Europe.
What are common use cases for the API?
Common integrations include: ATS platforms adding passive candidate sourcing, AI recruiting assistants, specialized talent sourcing tools, candidate pipeline builders, and outreach automation systems. Any application that needs to find and reach professional talent can benefit from the API.
