SCEDC Web Services
The tables below describe the web services available at the SCEDC. FDSN web services follow the FDSN API - a standard followed by many seismic networks. In addition, many scientific programming frameworks such as ObsPy and MatLab provide libraries that use these APIs.

Web services can be accessed in a number of different ways:
- Small requests can be handled through your browser
- Dedicated clients are available for making more complex or larger queries:
- IRIS Fetch scripts: Command line scripts for accessing data via web services. SCEDC specific info. and information on using the scripts with other data centers.
- irisFetch.m: A MATLAB library created by IRIS that allows direct access to data.
- ObsPy: The ObsPy project is dedicated to providing a Python framework for processing seismological data. Included in this framework is the capability to retrieve data from FDSN web services.
- Automated or scripted requests can be made using programs such as wget or curl.
Note: For POST users, there are known issues with wget v1.12 and https. This version does not correctly handle some properties in SSL certificates and may fail with the error ERROR: certificate common name doesn't match requested host name. We recommend upgrading to a higher version of wget or using curl instead.
