# Fraud Insight SDK
Go beyond identity verification and understand the signals behind every customer session. The Fraud Insights SDK analyses device and browser characteristics, IP and geolocation signals, device and account velocity, incognito and Tor usage, remote access tools, and behavioural patterns to build a contextual risk profile for each session. The SDK is compatible with Web, Android, and iOS, enabling businesses to apply behavioural risk intelligence across their digital channels.
Designed for financial institutions and fintechs, the SDK helps identify suspicious behaviour that traditional KYC checks may not detect. Use behavioural signals to detect account takeover, synthetic identities, mule activity, remote assisted sessions, and other fraud indicators before they result in financial loss. Scores and signals can be evaluated in real time and incorporated into your existing fraud, onboarding, and transaction decisioning workflows across web and mobile applications.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://doc.youverify.co/api-reference-sdk/sdk/fraud-insight-sdk.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
