Sample requests

Publicly Available Data

Data can be obtained using any program supporting the HTTP-GET method, e.g. your favourite web browser:

Restricted Data (authenticated users only)

ITACA Administrators and users with special authorizations can access data intended for internal use and/or embargoed.
Data can be obtained using any program supporting the HTTP-POST method, e.g. CURL:

curl -X POST -F "message=@path/to/token.txt" "https://itaca.mi.ingv.it/itaca40ws/gmm/1/query?eventid=USGS-usp000bg0m"

HTTP-POST variables (required)
