FAQ
How does it integrate with my existing AI calls?
Point your AI SDK base URL to our proxy endpoint. No other code changes needed — we intercept, scan, and forward (or block) transparently.
What sensitive data patterns does it detect?
Out of the box: emails, phone numbers, SSNs, credit card numbers, AWS/GCP/OpenAI API keys, JWTs, private keys, and custom regex rules you define.
What happens when sensitive data is detected?
You choose: block the request entirely and return an error, or sanitize by replacing sensitive values with safe placeholders before forwarding to the AI provider.
