{% hint style="info" %}

Find out more about the usage limits here
{% endhint %}

This function allows users to scan any Telegram username and retrieve a history of previous usernames associated with the account. This enables users to easily verify project team members on Telegram as part of the process of assessing the team's legitimacy.

In Telegram, each user is assigned a unique numerical ID that remains unchanged throughout the account's active period. As a result, our data is highly accurate, as all information is determined based on the User ID and observed usernames.

### What would our scan results consist?

1. Any previous usernames used by the User ID & Date seen

> If there are no results of any previous usernames, it would not be considered a successful scan. Hence not taking up any of your daily quota.
