“NIH award search” usually means one specific tool: NIH RePORTER (RePORT Expenditures and Results), the public database of NIH-funded research projects, maintained by the NIH Office of Extramural Research. It answers a different question than the funding-opportunity search most research administrators reach for first — where Grants.gov and NIH’s own funding announcements tell you what NIH is currently willing to fund, RePORTER tells you what NIH has already funded, to whom, for how much, and with what results. This guide covers what NIH RePORTER actually does, how it differs from forward-looking opportunity search, what a search returns, and how to get the same data programmatically or in bulk.
What NIH RePORTER is
NIH RePORTER is a free, public web application at reporter.nih.gov that lets anyone search NIH’s repository of funded research projects and see the publications and patents that resulted from that funding. It is operated by the Office of Extramural Research (OER), the NIH office responsible for extramural grants policy and administration. Enter search criteria into the RePORTER query form, get a hit list of matching projects, and click through to a project details page for the full record — award amount, project abstract, principal investigator, awardee organization, and linked publications.
The database is refreshed weekly. Each update adds newly funded projects and also revises existing records — a change of grantee institution, a revised award amount, a new fiscal-year increment on a multi-year award — so RePORTER reflects the current state of an award, not a static snapshot from the year it was first funded.
NIH RePORTER vs Grants.gov: two different directions
These two tools are the most common source of confusion for anyone new to NIH award search, because both are official federal grant databases, but they point in opposite directions in time:
- Grants.gov (and NIH’s own funding-opportunity announcements) is forward-looking: it lists open and upcoming funding opportunities across federal agencies, for applicants who haven’t yet been funded. See CASRAI’s NIH Grants: An Overview for how NIH funding announcements and mechanisms work at the application stage.
- NIH RePORTER is backward- and present-looking: it lists projects that have already received a notice of award, whether the award closed years ago or is still active. It answers “who has NIH funded to study X” or “what has this investigator or institution received,” not “what can I apply for.”
A research administrator moves between the two at different points in the grant lifecycle: Grants.gov and agency funding-opportunity announcements during proposal development, RePORTER during landscape analysis, competitive-intelligence work, verifying an investigator’s current and pending support, or checking a specific award’s status after it’s been made.
What you can search for
RePORTER’s query form supports searching by, among other fields:
- Principal investigator or co-investigator name
- Awardee organization (institution) name, including by state or country
- Project number, in full or by component (activity code, Institute/Center, serial number)
- Free-text keyword search across project titles, abstracts, and terms
- Fiscal year, funding mechanism (e.g., R01, K99, U01), and NIH Institute or Center
- Award amount ranges and award/budget dates
Combining fields narrows the results — for example, all R01 awards from a specific Institute in a given fiscal year, or every project a named investigator has held across their career, active or closed.
What a project record shows
A RePORTER project details page includes the project abstract and public health relevance statement as submitted by the awardee, the total award amount for the current budget period (and, for multi-year projects, the history of prior budget periods), the principal investigator(s) of record, the awardee institution, the NIH Institute/Center and activity code, and — where NIH has been able to link them — the publications and patents attributed to that project, drawn from PubMed and related linkage data. This publication linkage is one of the more useful features for research administrators doing progress-report preparation or verifying an investigator’s productivity claims: it’s an independently maintained cross-reference, not self-reported.
Programmatic access: the RePORTER API
For anyone pulling more than a handful of records, NIH publishes a REST API at api.reporter.nih.gov, currently on its second major version (v2), which exposes both project and publication data for programmatic queries — the same underlying data as the web interface, structured for scripted retrieval, institutional dashboards, or integration into a local CRIS or research-information system rather than one-off manual lookups. NIH’s own guidance asks API users to limit request rates (no more than roughly one request per second) and to schedule large batch jobs for off-peak hours (weekends, or weekday nights between 9pm and 5am Eastern) rather than during business hours, to avoid straining the service other users depend on.
Bulk data: ExPORTER
For a full annual extract rather than a query-by-query pull, NIH publishes ExPORTER: downloadable, structured data files (one release per fiscal year, covering project, abstract, publication, and patent data) intended for offline analysis, institutional data warehousing, or loading into a local system rather than repeated live API calls. This is the more appropriate route for an office building an internal dashboard of institution-wide NIH funding history, as opposed to looking up a single award.
Federal RePORTER: beyond NIH
NIH RePORTER’s sibling tool, Federal RePORTER, extends the same search-by-project model to scientific awards data from other US federal agencies, not just NIH, through its own API at api.federalreporter.nih.gov. It’s the tool to reach for when the award you’re trying to trace was funded by a different federal science agency, or when a cross-agency funding history is the actual question — a common need in multi-PI, multi-institution grant strategy work.
Why research administrators use NIH award search
In practice, NIH RePORTER shows up in several recurring research-administration tasks:
- Prior and current support verification — confirming what NIH funding an investigator already holds, for Other Support disclosures or before submitting a new, potentially overlapping application.
- Competitive and landscape analysis — seeing what a given Institute has already funded in a research area before an investigator commits time to a proposal in that space.
- Funding-history documentation — pulling an institution’s or a PI’s full NIH award history for internal reporting, biosketch preparation, or a promotion/tenure dossier.
- Portfolio and trend analysis — grants offices and research-development staff tracking how a specific Institute’s funding by mechanism or activity code shifts across fiscal years.
- Verifying award details after a notice of award — confirming the officially recorded project number, budget period, or awardee-of-record matches what the institution has on file.
Because RePORTER’s project and person data function much like a public, read-only research information system for NIH’s own award portfolio, the same conceptual building blocks used across CRIS infrastructure apply: a project record, a person record for the PI, and an output record for each linked publication or patent, tied together the way an institutional CRIS ties grants, researchers, and outputs together internally.
Data freshness and limitations
A few practical caveats worth knowing before relying on RePORTER for anything decision-critical: the weekly update cycle means a very recently issued notice of award may not appear yet; publication and patent linkage depends on NIH’s own matching process and can lag or occasionally miss a real link; and RePORTER covers NIH awards specifically — for other US federal science agencies, use Federal RePORTER instead, and for open, not-yet-awarded funding opportunities, RePORTER is the wrong tool entirely (use Grants.gov or the funding agency’s own opportunity listings).
Frequently asked questions
Is NIH RePORTER the same as Grants.gov?
No. Grants.gov lists open funding opportunities you can still apply to, across federal agencies. NIH RePORTER lists NIH projects that have already been awarded — it’s a record of funded research, not a place to find new opportunities.
How do I find all NIH grants awarded to a specific institution?
Use the awardee organization field in the RePORTER query form, optionally combined with a fiscal-year range or Institute/Center filter to narrow results; for a full historical extract rather than a browser query, use ExPORTER’s annual data files instead.
Can I search NIH RePORTER by grant or project number?
Yes — the query form accepts a full or partial NIH project number, including by individual component (activity code, Institute/Center designation, serial number), which is useful when you have a partial number from a notice of award or a citation.
Is there an API for NIH award data?
Yes — the RePORTER API at api.reporter.nih.gov exposes project and publication data for programmatic queries, currently on version 2. NIH asks API users to keep request rates low and to run large jobs during off-peak hours.
How current is the data in NIH RePORTER?
NIH RePORTER is updated weekly, with both new awards and revisions to existing records (institution changes, revised amounts, new budget-period increments) included in each update.
