OrgHunter for AI, ML & Data Science Projects

OrgHunter is more than a charity search tool — it is a structured, domain-specific data source that is ideal for powering AI and machine learning solutions. With stable identifiers, rich categories, eligibility flags, and up-to-date status information, OrgHunter can become the charity layer inside your AI stack.

Build Charity-Aware AI Assistants
  • Ground LLMs in verifiable data to answer questions like "Which local charities support education?" or "Is this nonprofit in good standing?"
  • Use EINs as stable IDs to link charities to your internal systems and knowledge graphs.
  • Feed OrgHunter JSON responses directly into your RAG pipelines, AI agents, and tools.
Recommendation & Personalization Engines
  • Combine OrgHunter charity attributes with donor behavior to recommend causes that match interests and values.
  • Vectorize missions, tags, and locations to enable "Because you support X, you may also like Y" experiences.
  • Curate AI-driven cause lists for CSR programs, loyalty rewards, and fundraising campaigns.
RAG, Embeddings & Knowledge Graphs
  • Index charity descriptions, categories, and locations in your vector database to enable semantic search and similarity queries.
  • Build a knowledge graph using EIN, NTEE codes, mission statements, and charity relationships to power intelligent querying.
  • Retrieve the most relevant charities at query time to enrich LLM prompts with precise and up-to-date domain context.
Risk, Compliance & Eligibility Models
  • Use OrgHunter eligibility and revocation status as features in internal risk, fraud, and compliance models.
  • Track status changes over time to support audit-ready workflows for donation handling and grant distribution.
  • Automatically filter out ineligible organizations before presenting options to users or AI systems.

All OrgHunter APIs return structured JSON responses that are easy to integrate with LLMs, vector databases, ETL pipelines, and analytics platforms.
