You must click here for very important D&B information.

Where can I find all the data elements in the atom feed?

Below are URLs that display the data elements within sample data feeds for different versions.

How do we fetch deleted contracts?

The URL below will fetch the deleted contracts.

Would pulling thousands of records at a time be a problem for the atom feed?

Pulling 10K records per search in the limit for Atom Feed would not be feasible. 1 atom feed thread is limited to pull only 10 records per search, however, you can run 10 threads per search, so technically you would be able to pull 100 records per search

What time of day is good to schedule atom feed downloads?

Any time after 9:00 AM eastern time.

Do I need an FPDS account to use atom feed?

The atom feed is for public use so no account is required. If you are a user that needs access to DoD or FAADC feeds, please go to www.fsd.gov or call (866) 606-8220 to request an Authenticated ATOM Feed account.

Atom feed is updated on a daily basis. What data element should I use to extract the contracts?

Use the 'Last Modified Date' filter. For the Public and DoD feeds, different search criteria is available with examples in the URL below:
