At Grants.gov, we strive to accommodate real-world applications and make it as easy as possible to connect with any funding opportunities for which you may be eligible.
One way we do that is by providing an extensive list of web services for applicants and grantors to perform Find and Apply functions using our System-to-System (S2S) interface, which uses SOAP/XML-based technologies.
S2S users can integrate the Grants.gov web services into their existing grant management system, providing a more seamless experience for their own staff.
Recently, we extended our services by developing two new RESTful APIs. We’re excited to share them and explain a little about their functionality.
The two new APIs are:
- Endpoint: search2
- Purpose: This endpoint powers the search grant functionality
- Endpoint: fetchOpportunity
- Purpose: This endpoint retrieves detail opportunity data.
These new services do not require authentication to use (no keys or certificates required), as their sole purpose is to search publicly available funding opportunities.
There are additional benefits, as well: The RESTful APIs are designed to more easily adapt to users’ changing needs. In fact, the move to RESTful APIs is part of an effort to facilitate future modernization efforts.
For more information, please visit our RESTful APIs webpage on Grants.gov.
We hope these updates will continue to improve the user experience on Grants.gov.
