# REST API Manual
# The Base URL
The base URL of all calls to the RIPE Atlas APIs for this particular version is
https://atlas.ripe.net/api/v2/. You can append the name of the object type you want information from to form a URL. For example:
A URL that contains information about one object or a series of objects is called a Resource.
Note that the API is only served over TLS.
The object part of the URL should be plural and lower case. For example:
# About API versioning
The APIs use semantic versioning (opens new window) from version 2 onward. This means that we will:
- Update the patch version (2.0.x) whenever we fix bugs in the API
- Update the minor version (2.x.0) whenever we extend an API without breaking backwards compatibility.
- Update the major version (x.0.0) whenever we make backward-incompatible changes
After updates for the patch and minor versions, previous versions will no longer be available. After an update of the major version, the previous API will be still available. Only the major version number is mentioned in the base URL.
An example of a valid URL looks like this:
As you can see, the API returned a list of three measurements.
