One API that encrypts, proves, and delivers sensitive data. Your code is protected from line one. Your customers get real privacy. The server sees nothing.
When you need to see sensitive data — production logs, secrets, DB results, API keys — Capsule lets you do it without opening the whole system and without creating exposure risk.
4 endpoints. Blind relay. Zero storage.
Every request requires a Bearer token in the header. Create a key at /get-started
