Jeremy: a lot of this actually already exists. For one, Scout operates entirely on public APIs. When you do a search on Scout and are waiting for search results to come back, Scout is doing an API request to our Open States API, Real Time Congress API, and Capitol Words API.

http://openstates.org/api/
http://services.sunlightlabs.com/docs/Real_Time_Congress_API/
http://capitolwords.org/api/

For any alerts you create on Scout, we provide an RSS version of your subscription, which can be used to integrate with other websites. We also offer a JSON version -- though in many cases, you're better off directly integrating with one of the source APIs Scout is using, all of which offer JSON. All feeds in Scout require a user account and associated alert, while our public APIs only require that you have registered an API key.

Finally - if you've already registered a Sunlight Labs API key (which can be done here: http://services.sunlightlabs.com) under the same email your Scout account is registered under, we'll detect that and start showing you direct links to the source data, on the sidebar of your search results. This makes Scout a sort of living documentation for our other public APIs.
