FRS API

The FRS API exposes several RESTful web services for querying and submitting data with FRS. 

Connect to FRS API

Contact the FRS team to request access to the FRS API. The FRS team will guide you through the process of getting a NAAS account, configuring FRS for your account, and determining the level of effort for you data goals with FRS.

The required FRS API account creation (NAAS account) is integrated into the Environmental Information Exchange Network (EN). See the FRS API Account (NAAS) Setup Information or ask for guidance from the FRS team.

After creating an account the FRS team will help in validating your developer's approach in the pre-production API and then give access to the production API.

The technical details of the FRS API are documented in the FRS Swagger pages:

  • Pre-production Query API Swagger Page (for testing purposes)
  • Pre-production  Submit API Swagger Page (for testing purposes)
  • Production Query API Swagger Page
  • Production Submit API Swagger Page

For an example of connecting to the FRS API, see this 2023 open source Python FRS API client.

Note - duplicated FRS API documentation is on the Exchange Network at the Environmental Information Exchange Network documentation of FRS API page.
