Stackalytics JSON API v1.0

Note

JSON API v1.0 corresponds to Stackalytics v0.X

1 General API information

This section contains base info about the Stackalytics JSON API design.

1.2 Request / Response Types

The Stackalytics API default response format is “application/json”. However if HTTP attribute ‘callback’ is specified then JSONP response is returned. That allows to use response in client-side code and avoid same-host requests limitations.

Example:

GET /api/1.0/stats/companies

or

GET /api/1.0/stats/companies?callback=myCallback
Accept: application/javascript

1.3 Faults

The Stackalytics API returns an error response if a failure occurs while processing a request. Stackalytics uses only standard HTTP error codes. 4xx errors indicate problems in the particular request being sent from the client and 5xx errors indicate server-side problems.

2 Methods

2.1 Common Parameters

All requests support common set of parameters that allow to filter resulting data.

Parameter	Description
release	Name of OpenStack release or ‘all’, by default current release
project_type	Type of project, by default ‘openstack’
module	Name of module (repository name)
company	Company name
user_id	Launchpad id of user or email if no Launchpad id is mapped.
metric	Metric: e.g. ‘commits’, ‘loc’, ‘marks’, ‘emails’

2.1.1 Other query parameters

Data can be queried by time period:

Parameter	Description
start_date	When the period starts
end_date	When the period ends

Both start_date and end_date take as their argument Unix time

For example to specify 'Thu Jan  1 00:00:00 UTC 2015' the value would be 1420070400

Note that if both release and time period are specified then the data is selected for the intersection (thus the useful way is to specify release as all).
