Environmental health intelligence delivered as infrastructure.

Environmental health insight

The primary endpoint. Accepts a health sensitivity, location and time window and returns a complete AI-synthesised environmental health assessment grounded in real-time environmental signals and peer-reviewed evidence. Powers the public research tool at app.vasus.ai.

The pipeline runs four stages: (1) environmental signal ingestion from Google AQ, Weather and Pollen APIs; (2) semantic retrieval from 535,000+ PubMed papers; (3) LLM gate for citation relevance filtering; (4) AI synthesis producing a condition-specific risk assessment with inline citations.
