Data & Methodology

• NIH RePORTER and ExPORTER downloads for funded projects and abstracts.
• Activity codes, fiscal year totals, and organization details from official NIH datasets.
• FOA notices for deadlines and mechanism rules when referenced in guides.

• Weekly pulls for newly awarded projects used in Weekly Updates.
• Monthly aggregation for trends (yearly totals, top institutes) shown in Trends.
• Investigator search endpoints re-index weekly to capture new PIs and institutions.

• Normalize institution names (e.g., “UCSF” → “University of California, San Francisco”).
• Deduplicate projects across supplements/subprojects using project IDs.
• Flag missing abstracts or partial cost data so users can click through to NIH RePORTER.

These endpoints power the app and are grounded in NIH data:

• /api/recent-grants: returns projects awarded in a recent period with abstracts and award amounts.
• /api/fetch-trends: aggregates yearly totals and activity codes for charts.
• /api/fetch-pis: searches investigators by keyword, institute, and funding role.
• /api/check-pi: quick status check for a PI's active awards.

When you see numbers on the site, they are derived from these endpoints and linked back to NIH sources where available.

• NIH sometimes redacts abstracts; we label these and provide the project number for direct lookup.
• Cost data (direct/indirect) may lag; always verify in the official notice of award.
• Historical trends can shift after NIH backfills late-reported data; charts note the last refresh date.
