Department of Commerce Developer Application Programming Interfaces (APIs)


On Commerce's Developer Resource page you can find and access featured data or web services from the Department's agencies and mission areas. This page will be updated as agencies make available new developer tools and data resources, so be sure to check back often. Questions and feedback about this page can be directed to Webmaster[at]doc[dot]gov.

Bureau of Economic Analysis

Bureau of Economic Analysis API - The API provides all regional data and national economic data released by BEA.

Census Bureau
Census Bureau API - The API provides a range of popular data sets through a combined endpoint. The following data sets are currently available through the API: 2010 Census Summary File 1 (SF1), American Community Survey 5 Year Data, 2000 Census Summary File 1 (SF1) and Summary File 3 (SF3), 1990 Census Summary File 1 (SF1) and Summary File 3 (SF3).

Automated Export System - This API enables Internet application developers and providers to allow their users to pass data from their own third party applications into AESDirect. This makes it easier for end-users to enter data into AESDirect and eliminate double entry of data into both the third party application and AESDirect.

International Trade Administration

Through its Trade Developer Portal, the International Trade Administration (ITA) provides APIs to data intended for public use and dissemination. Trade experts from ITA and from Trade Promotion Coordinating Committee (TPCC) agencies produce the wide spectrum of data provided by these APIs.  ITA publishes them to help developers access authoritative information on exporting that they can then make available to businesses, which is a core tenet of the ITA.

Available datasets include:

  • ITA’s Market Research Library - Country and industry reports that are produced by ITA’s trade experts.
  • ITA Offices & Center Locations - Contact and address information for all of ITA’s domestic and international export assistance centers.
  • Trade Events - Events for U.S. businesses interested in selling their products and services overseas.
  • Trade Leads - Contract opportunities for U.S. businesses selling their products and services overseas.
  • Trade News & Articles - News and articles written by Trade Specialists working in the Federal government.
  • Consolidated Screening List - combined screening lists from the Departments of Commerce, Treasury, and State that contain names of individuals and companies with whom a U.S. company may not be allowed to do business with due to U.S. export regulations, sanctions, or other restrictions.

National Institute of Standards and Technology

By following the description of the web service contained in the WSDL, applications will be able to automatically query the service for validation of CDA-based documents.

National Oceanic and Atmospheric Administration
Meteorological Assimilation Data Ingest System - The MADIS Application Program Interface (API) is a library of subroutines, callable from Fortran, which provides access to all of the observation and quality control (QC) information in the MADIS database (referred to as the "FSL database" in the API documentation), and/or other supported meteorological databases (i.e., the NWS AWIPS netCDF database)

Each SOAP web service is offered with a sample request, sample response and sample Java Client code to our users to facilitate their work with seamlessly connecting to the services and to retrieve the data of interest.

Center for Operational Oceanographic Products and Services - The Center for Operational Oceanographic Products and Services (CO-OPS) Sensor Observation Service has implemented three operations  that provide access to sensor observations and measurement data via a spatio-temporal query that can be filtered by phenomena, provide the means to access SOS service metadata, retrieve detailed information about the sensors and processes generating those measurements.

Environmental Research Division's Data Access Program - The Environmental Research Division's Data Access Program is a data server that gives you a simple, consistent way to download subsets of scientific datasets in common file formats and make graphs and maps.

Space Physics Interactive Data Resource Web Services - Space Physics Interactive Data Resource (SPIDR) is designed to allow a solar terrestrial physics customer to intelligently access and manage historical space physics data for integration with environment models and space weather forecasts. SPIDR is a distributed network of synchronous databases and 100% Java middle-ware servers accessed via the World Wide Web.
