If a medical emergency hits, you are not just sick—you are financially paralyzed. Traditional insurance? It's a fortress you can't enter. No formal contracts, no digital history, and a bureaucracy that takes weeks to pay out. I built SeguraFácil to break this wall.

It can read a medical report and decide if a claim is valid. But here was the problem: To pay the worker, the AI needs access to the company’s PayPal API keys. If I store the keys in the code? Huge risk. If the AI is compromise
