# Quick start guides
Learn how to monitor or verify information about natural persons or organisations in just a few steps. Refer to our API documentation about the Information API or the Monitoring API for detailed information about all the available endpoints and properties.
In order to follow the quick start guides below, you will need some test data. Exactly what kind of data you need will depend on the API you are using and the endpoints you want to call. For example, you must provide the organisation number of a company to test organisational lookups, or you might need a test personal ID number to test natural person monitoring. You can find information about how to access relevant test data on the Test data page.
# Before you start
If you don't have an account already, you have to create a free Signicat account (opens new window).
# Monitoring or information services
If you want to monitor information about users as it changes over time (e.g. when they change addresses), use the Monitoring tab of the guide. If you just want to look up information about a person or organisation, use the Information tab.
