NIH RePORTER (Research Portfolio Online Reporting Tools) provides a comprehensive API for searching and analyzing grants funded by the National Institutes of Health and other agencies within the U.S. Department of Health and Human Services. The database includes project details, funding amounts, publications, patents, and clinical studies linked to funded research.
RePORTER is the authoritative source for NIH grant data and covers billions of dollars in annual biomedical research funding. The API enables programmatic access to search for funded projects, retrieve associated publications, and analyze funding trends across NIH institutes, study sections, and disease categories.
The v2 API is a modern RESTful service that accepts JSON POST bodies for search requests and returns structured JSON responses. It is completely free and requires no authentication.
No authentication is required. The NIH RePORTER API is a free public service.
