# Account risk signals

Get risk signals for connected account fraud, delinquency, and website legitimacy.

Radar provides programmatic access to risk signals through the Account Signals API. These signals provide risk intelligence for your connected accounts, enable you to build automated workflows, and integrate risk data directly into your platform’s operations.

## Risk signals

[Fraudulent merchant](https://docs.stripe.com/radar/fraudulent-merchant.md): Detect connected accounts engaging in fraudulent activity, such as misrepresenting goods or services, processing unauthorized transactions, or committing first-party fraud.

[Merchant delinquency risk](https://docs.stripe.com/radar/merchant-delinquency-risk.md): Identify connected accounts showing financial distress indicators that might lead to unfulfilled orders, increased disputes, or the inability to cover refunds.

[Fraudulent website](https://docs.stripe.com/radar/fraudulent-website.md): Flag connected accounts operating deceptive or policy-violating websites, including sites with misleading product claims or fake storefronts.

## How it works

Stripe continuously evaluates your connected accounts using machine learning models trained on millions of payments across the Stripe network. When a risk signal changes, Stripe sends a webhook event to your endpoint so you can [take action](https://docs.stripe.com/radar/account-fraud-prevention.md#take-action).
