Active Monitoring screens your watchlist with TRM Wallet Screening, using your own TRM API key, on the schedule you choose. TRM Labs is the blockchain analytics provider that scores the risk of each address. The **screening interval** is how often Active Monitoring screens the whole watchlist. This guide covers four operations: store the key, set the screening interval, start screening, and remove the key. For how screening works, see [Watchlist and Screening](/ace/active-monitoring/concepts/screening).

## Prerequisites

- A TRM Labs account with access to the [Wallet Screening API](https://www.trmlabs.com/blockchain-intelligence-platform/wallet-screening), and its API key from your TRM Labs dashboard.
- To use the **API** tab, an ACE API key, sent in the `Authorization: Apikey <API_KEY>` header of each request. See [Create an API key](/ace/getting-started/account-setup#3-create-an-api-key). It is a different key from your TRM API key.

## Store the TRM API key and choose the interval

## Start screening

Starting screening needs four things to exist: the TRM API key, a screening interval, a [monitoring rule](/ace/active-monitoring/guides/configure-monitoring-rules) on at least one token, and at least one address on the [watchlist](/ace/active-monitoring/guides/manage-watchlist). The first run starts immediately and repeats at the interval.

## Stop screening

## Remove the TRM API key

Removing the key stops screening: Active Monitoring has no key to call TRM with, and it screens nothing until you store a new key. Decisions already created stay in the log.
