The services component of the USGS Earthquake Hazard Toolbox provides
documentation and examples of the web service endpoints used by the
individual applications in the USGS Earthquake Hazard Toolbox.
While these web services are publicly accessible, we ask that users not
over-use them, for example by making many calls in a short period of time.
If web service usage impacts the performance of our web applications or the
cost of maintaining the services increases due to increased usage, we
reserve the right to limit access in the future.
We request that users who want to perform many calculations use the USGS
hazard codes
directly.
