The Tinfoil SDKs are drop-in replacements for OpenAI clients with automatic security verification on every connection. Available for Python, TypeScript/Node, Go, Rust, and Swift. The CLI can also act as a reverse proxy.

​
Available SDKs

Read the full documentation for your SDK:

Python

JavaScript

Go

Rust

Swift

CLI

If you’d like to see an SDK for a different language or runtime, please reach out at [email protected] and we’ll prioritize adding support for it.

​
Why you should use the SDKs

The SDKs make it easy to integrate Tinfoil into your applications without having to worry about encryption, attestation verification, or other security pitfalls. All the privacy and integrity features offered by Tinfoil are automatically verified for you and all connections are blocked in case of verification failure. Each SDK is designed to be a drop-in replacement for OpenAI clients. This means you can continue to use the chat completions or responses API formats with Tinfoil models. However, not all backend features are supported or enabled for all models. If you experience issues, please don’t hesitate to contact us. For accessing the inference endpoint directly via HTTPS without an SDK (which we discourage for production workloads), see Direct API Access.
