Instantly access empirical models of atmospheric density and composition that are recommended by the Committee on Space Research (COSPAR) for satellite drag calculations.

NRLMSISE-00 is recommended for composition calculations and was developed by the US Naval Research Laboratory.

JB2008 is a newer model and is recommended for density calculations at altitudes above 80 km. It was developed by Space Environment Technologies and the US Air Force Space Command.

The Atmosphere API wraps the original source code for both. It is free for research and development purposes and rate-limited to 1000 calls per day.

High energy galactic cosmic rays and bursts of solar energetic particles collide with nuclei of gases in the atmosphere, leading to a cascade of nuclear and electromagnetic reactions. The result is a complex mix of directly and indirectly ionising radiation, the intensity and composition of which varies spatially and temporally. Understanding this mix is important for a variety of applications, including estimating the exposures of aircrew, pilots, and frequent flyers during air travel.

The PARMA model, developed by the Japan Atomic Energy Agency (JAEA), can instantaneously estimate cosmic ray fluxes of neutrons, protons, ions, muons, electrons, positrons, and photons for a given date, latitude, longitude, and altitude. A comprehensive description of PARMA can be found in the publications here and here

The Terms and Conditions of PARMA are described here. Use of the API acknowledges you have read and agreed to those Terms and Conditions.

We provide an open RESTful API to the model and added functionality to calculate Effective Dose and Ambient Dose Equivalent using conversion coefficients. The API is free but usage is limited to 1000 API calls per day.

Amentum Pty Ltd is not responsible nor liable for any loss or damage of any sort incurred as the result of the use of the API.

BBC Nitro is the BBC's application programming interface (API) for BBC Programmes Metadata.

BC Laws is an electronic library providing free public access to the laws of British Columbia. BC Laws is hosted by the Queen's Printer of British Columbia and published in partnership with the Ministry of Justice and the Law Clerk of the Legislative Assembly.BC Laws contains a comprehensive collection of BC legislation and related materials. It is available on the internet in two forms:First: The library is available as a web site in which users can browse and search the laws of British Columbia.Second: The library is available as a portal to legislation in raw XML data format, accessible via the BC Laws API2. This direct access to raw data is intended to enable third parties to build or add their own custom applications based on the structure of the data and all the associated search functionality inherent in that structure. The BC Laws website itself is an example of one such application. Please note that you may experience issues when submitting requests to the delivery or test environment if using this [OpenAPI specification](https://github.com/bcgov/api-specs) in other API console viewers.

This is an API for accessing information about bicycling related incidents. You can find the source code on GitHub.

City Context provides a straightforward API to access UK Open Data: crime statistics, schools, demographics and more.

This is an API for accessing all sorts of college football data. It currently has a wide array of data ranging from play by play to player statistics to game scores and more.

You can use the CORE API to access the resources harvested and enriched by CORE. If you encounter any problems with the API, please report them to us.


The API is organised by resource type. The resources are articles, journals and repositories and are represented using JSON data format. Furthermore, each resource has a list of methods. The API also provides two global methods for accessing all resources at once.

Response format

Response for each query contains two fields: status and data. In case of an error status, the data field is empty. The data field contains a single object in case the request is for a specific identifier (e.g. CORE ID, CORE repository ID, etc.), or contains a list of objects, for example for search queries. In case of batch requests, the response is an array of objects, each of which contains its own status and data fields. For search queries the response contains an additional field totalHits, which is the total number of items which match the search criteria.

Search query syntax

Complex search queries can be used in all of the API search methods. The query can be a simple string or it can be built using terms and operators described in Elasticsearch documentation. The usable field names are title, description, fullText, authors, publisher, repositories.id, repositories.name, doi, oai, identifiers (which is a list of article identifiers including OAI, URL, etc.), language.name and year. Some example queries:

  • title:psychology and language.name:English

  • repositories.id:86 AND year:2014

  • identifiers:"oai:aura.abdn.ac.uk:2164/3837" OR identifiers:"oai:aura.abdn.ac.uk:2164/3843"

  • doi:"10.1186/1471-2458-6-309"

Retrieving the latest Articles

You can retrieve the harvested items since specific dates using the following queries:

  • repositoryDocument.metadataUpdated:>2017-02-10

  • repositoryDocument.metadataUpdated:>2017-03-01 AND repositoryDocument.metadataUpdated:<2017-03-31

Sort order

For search queries, the results are ordered by relevance score. For batch requests, the results are retrieved in the order of the requests.


The API methods allow different parameters to be passed. Additionally, there is an API key parameter which is common to all API methods. For all API methods the API key can be provided either as a query parameter or in the request header. If the API key is not provided, the API will return HTTP 401 error. You can register for an API key here.

This REST-API enables you to query station and stop infos

A RESTful webservice to request a railway journey - FREE plan with restricted access (max. 10 requests per minute). Please ignore the message in the API Console about the access token. Register to use an less restricted version, which requires an access token.

A RESTful webservice to retrieve data about the operational state of public elevators and escalators in german railway stations operated by DB Station&Service AG. Note: Production and sandbox environments use the same production backend server.

This REST-API enables you to query for private transport sharing offers provided by companies and cities in Germany, Netherland and Austria. You can search for informations about the rental stations (points or areas) where you can find the rentals by utilizing the /areas/ ressource. With the help of the proximity search in the /bookingproposals/ URI you can request the availabilities of the rentalobjects for spontaneous or planed usage in the future. Feel free to browse through data by setting the parameter 'providernetwork' to the value: 1: Search for car sharing offers provided by the Flinkster platform (http://www.flinkster.de) 2: Finding bike rental offers from Call a Bike (http://www.callabike.de) You can find more details in the documentation section (Unfortunately only available in german language). Have lots of fun and we are lucky to take notice of your products or getting your feedback.
