Prompt injection is untrusted content that tries to redirect an AI system's instructions.

## Why it matters

Treat external pages as evidence to inspect, not instructions to obey.

## Illustrative example

A company webpage tells a browsing agent to ignore its task and reveal secrets.

## What to check

Filtering alone does not replace tool permissions and careful system design.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
