Below is a fictitious research portal showing structured environmental exposure data for a 2,847-subject cardiovascular cohort. Pick any of the cohort's 4 sites to drill into 90-day trends and an Insight narrative for that location.

Use case · Research institution

Cohort exposure & mechanism research

Pull longitudinal environmental exposure for any cohort site, with PMID-traceable signals — without manually merging WHO, ECMWF, and PubMed.

90+ days
Saved per cohort vs assembling exposure history manually from raw sources.
The problem

Researchers studying environment-disease relationships spend weeks merging air quality data, weather records, and PubMed-traceable mechanistic signals. The data engineering eats the science budget.

The solution

vasus.ai exposes GET /v1/trends for daily-resolution exposure series at any location and time window, plus POST /v1/insight for the synthesis layer with PMID-grounded mechanistic narrative. Python-friendly clients with batch endpoints for cohort-scale pulls.

The outcome

Researchers move from data-engineering to analysis in days, not weeks. Reproducible exposure inputs that anyone can re-pull. PMID-traceable mechanisms that survive peer review. Citable methodology section ready out-of-the-box.

Integration steps

Four steps to ship

1
Pull historical exposure
GET /v1/trends with cohort site lat/lon, variables list, window_days. Daily-resolution series.
2
Aggregate to your unit of analysis
Subject-day, subject-week, or whatever your study design needs. Response includes pre-computed aggregates.
3
Cite the mechanistic synthesis
POST /v1/insight — risk_level, summary, key_mechanisms with PMID-traceable citations for your methods section.
4
Document and reproduce
Citable methodology block referencing API version, weight vectors, and exact request parameters. Reviewers can re-pull.
Relevant sensitivities
