PCCI provides OpenAI-compatible APIs with built-in end-to-end encryption. Every API call — chat completions, audio transcriptions, translations, file uploads, and tools — is protected by post-quantum cryptography from your device to our secure enclave and back.

​
Our mission

Make end-to-end encryption the standard for AI APIs. Every chat completion, transcription, translation, and file upload should be cryptographically protected with post-quantum security — no compromises, no plaintext exposure. Developer-friendly integration — Use our TypeScript SDK (PCCI SDK) for seamless integration, or run our local OpenAI-compatible server to use any OpenAI client library. Full type safety, comprehensive documentation, and straightforward error handling.
PCCI Platform Architecture

​
Why PCCI?

Zero plaintext exposure — Unlike standard API providers, your data never exists in plaintext on our servers. Encryption and decryption happen on your device and inside secure enclave only. OpenAI compatibility — No need to rewrite your applications. Same request/response formats, same model interfaces, same streaming protocols. Post-quantum ready — Hybrid encryption means you’re protected against quantum threats today, not in some distant future. Key sovereignty — You generate and control all encryption keys. We never have access to your KEK or plaintext data. Production-ready — Built for scale with proper error handling, rate limiting, file management, and comprehensive tooling.
