I have built a production-ready validator API to help stop prompt-injection, jailbreaks, unsafe tool calls, and system prompt leaks.

Endpoints: POST /validate and POST /validate_output

Actions: pass, block, sanitize, escalate

Check it out if you want to, I would be grateful for any feedback support@patrei.com

Happy to answer questions or dive into the design choices in the comments.
