NIH RePORTER Projects

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

Deferred

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.

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

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.

ToS & usage notes

What the source allows.

U.S. government public-domain works. The NIH RePORTER API v2 is key-less and public-domain; attribution to NIH RePORTER is the only requirement. Snapshot and attestation fields must be read from the specific artifact; no provenance fact currently links deterministically to a signature.

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.
How much data does this dataset hold?
179,957 funded-award records across fiscal years 2024–2026 — 81,521 distinct projects and roughly $98.8 billion in award dollars — as of the 2026-06-14 snapshot. 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.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
