# obspy.clients.iris.client.Client

class `Client`(base_url='http://service.iris.edu/irisws', user='', password='', timeout=20, debug=False, user_agent='ObsPy/1.1.1 (Linux-2.6.32-042stab134.8-i686-with-debian-wheezy-sid, Python 3.4.4)', major_versions={})

  Bases: `builtins.object`

  IRIS Web service request client.

  Parameters: | base_url (str, optional) Base URL of the IRIS Web service (default is `'http://service.iris.edu/irisws'`). user (str, optional) The user name used for authentication with the Web service (default an empty string). password (str, optional) A password used for authentication with the Web service (default is an empty string). timeout (int, optional) Seconds before a connection timeout is raised (default is `10` seconds). debug (bool, optional) Enables verbose output (default is `False`). user_agent (str, optional) Sets an client identification string which may be used on server side for statistical analysis (default contains the current module version and basic information about the used operation system, e.g. `'ObsPy 0.4.7.dev-r2432 (Windows-7-6.1.7601-SP1, Python 2.7.1)'`. major_versions (dict) Allows to specify custom major version numbers for individual services (e.g. major_versions={‘evalresp’: 2, ‘sacpz’: 3}), otherwise the latest version at time of implementation will be used.

  Example

      >>> from obspy.clients.iris import Client
      >>> client = Client()
      >>> result = client.distaz(stalat=1.1, stalon=1.2, evtlat=3.2,
      ...                        evtlon=1.4)
      >>> print(result['distance'])
      2.10256
      >>> print(result['backazimuth'])
      5.46944
      >>> print(result['azimuth'])
      185.47695
