NIH RePORTER

NIH RePORTER Projects

National Institutes of Health (NIH RePORTER) · Tier-1 · research-only (never on individual profiles)

Deferred
Source:NIH RePORTER·Snapshot May 2026Open official source ↗

NIH RePORTER is the National Institutes of Health's database of federally funded research projects, recording grant awards, principal investigators, awardee organizations, and fiscal-year funding. The schema and provenance contract are live; the first ingest snapshot is pending, so the table currently holds 0 rows.

What Fonteum uses it for

How this source shows up on Fonteum.

Tier-1 research-only context for studies on research activity and grant-funding networks. Will surface project title, fiscal year, award amount, principal investigators, and awardee organization at the aggregate level. Records are name-keyed (PIs by name; awardee org as affiliation); there is no NPI in the source, and NPI / entity-graph linkage is deferred — ambiguous matches are held.

What this source does NOT mean

A RePORTER record describes a funded research project — it does not measure provider quality, outcomes, or endorsement, and a named PI is not a Fonteum-asserted identity match to any specific provider profile. A grant award is not a Fonteum assessment.

What this dataset answers

Research and data questions this source supports.

  • 01Build a research dataset of federally funded NIH projects by institute, fiscal year, or awardee organization once the first snapshot lands.
  • 02Analyze grant-funding and research-activity networks at the aggregate, name-keyed level.
  • 03Track award amounts and project volume by awardee organization over fiscal years.
  • 04Combine grant-funding signals with ClinicalTrials.gov study activity for research-landscape studies.

Dataset size: 0 rows — first ingest snapshot pending (as of 2026-06-14)

Fields used

Per-field display contract.

Every field below has a `display_allowed` flag in the §94 provenance schema. Write-locked fields are captured to provenance for audit but never rendered on profile pages.

Limitations

What we can’t infer from this source.

  • First ingest snapshot pending — the table currently holds 0 rows. Figures will populate once the operator runs the ingest.
  • Tier-1 — aggregate research context only; never rendered on individual provider profiles.
  • Name-keyed: PIs are recorded by name and awardee organization as affiliation. There is no NPI in the source.
  • NPI / entity-graph linkage is deferred; ambiguous name matches are held, not written.

Frequently asked

Common questions about NIH RePORTER.

What is NIH RePORTER?
NIH RePORTER is the National Institutes of Health's public database of federally funded research projects. Each record carries a project title, fiscal year, award amount, principal investigators, and the awardee organization.
Why does this dataset currently show 0 rows?
The schema and provenance contract are live, but the first ingest snapshot is pending — so the table honestly holds 0 rows until that ingest runs. The NIH RePORTER API v2 caps results per window, so large fiscal years are pulled by organization-state subdivision with logged coverage gaps.
Are principal investigators linked to provider profiles?
No. RePORTER records are name-keyed — PIs are recorded by name and the awardee as an organization affiliation, with no NPI in the source. NPI / entity-graph linkage is deferred; a named PI is not a Fonteum-asserted identity match to any specific provider profile.
Does a grant award indicate provider quality?
No. A RePORTER record describes a funded research project. A grant award is not a measurement of clinical quality or outcomes, and it is not a Fonteum assessment of any provider.
How can I cite this data?
Use the attribution 'Source: NIH RePORTER (National Institutes of Health)'. The NIH RePORTER API v2 is key-less and public-domain; attribution to NIH RePORTER is the only requirement.
