# 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](https://docs.stripe.com/api/v2/signals/account-signals.md?api-version=preview). 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.

[Payment delinquency exposure](https://docs.stripe.com/radar/payment-delinquency-exposure.md): Estimate the dollar amount at risk from disputes and refunds if a connected account becomes delinquent.

[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).
