What public APIs are provided by Governments to the public?

Question

I stumbled across NOAA's SOAP Service and it got me thinking. What other eGovernment services are provided to Business and the general public by Governments? I know the United States has a lot APIs, but what about other governments like the European Union. I am interested in not just SOAP but any Remote Procedure Call (RPC) service available to the public over the internet. I am interested in more than just data sources, but other types of APIs as well.

Answer 1

US Government Web Services and XML Data Sources

Answer 2

I live in NZ and there are quite a few useful public government webservices available:

InfoConnect Highway Info - Supplies traffic count information, traffic web-cams, highway location referencing etc

Broadband Map - Public webservice that allows one to get a feel for the overall coverage of various broadband services in NZ

GeoNet - Earthquake, tsunami data (which is quite relevant as we just had a massive earthquake today)

Hope that helps ya in some way!

Found some more from ProgrammableWeb:

Australian Business Number Lookup

OpenSecrets.org - U.S. Political Data Lookup API

European Open Patent Services API

UK police force mapping service

United Nations Information Service

Project Nimbus is a public initiative in Singapore by a group of developer to gather and make available information collected by the Singaporean government and private organizations into the form of an easily digestible and accessible API.

The project is still in its infancy but already has some interesting data available for consumption, such as:

• Local traffic conditions
• Public library locations
• Local weather information

Suddenly I feel proud to be a British Citizen... are you ready? Good:

HMRC (the lovely people who take our tax off us) provide a fully documented API, see here, for filling in just about every form they have. Not only that, but they define a whole set of schemas and everything available here: http://www.cabinetoffice.gov.uk/govtalk/schemasstandards.aspx

All I can say is my estimation of the UK gov't went up when I disccovered that.

Unfortunately that's as far as it goes, but still, an API for interacting with the HMRC is very, very useful.

We also have data.gov.uk where an entire archive of government data is made available; I believe there are APIs for accessing it too.

Some German governments (we have multiple states) provide the Zuständigkeitsfinder, a SOAP-Interface where you can search for the nearest person responsible for several so-called "Anliegen" like getting a new passport, nominating someone for the Bundesverdienstkreuz (a medal given for extraordinary engagement for the public) or getting a permission to drive a truck at the weekend in the city.
