TrustedRails gives you an OpenAI-compatible API for the best open-source models. Standard billing in USD, your data never leaves your control.
Powerful open-source models through a familiar API. No infrastructure to manage.
Just change the base_url in any OpenAI SDK. Supports Python, JS, and other clients.
Pay as you go with a card. No commitments, no minimum spend. Clear per-token pricing.
Unlike major providers, your prompts and completions are never used for training. No vendor sees the full picture.
Open-source models, standard API. Switch to or from TrustedRails in two lines of code.
From sign-up to first inference in under a minute.
Sign up with email or Google. Takes 30 seconds, no credit card required.
In the dashboard, create a key for your application or environment.
Point any OpenAI-compatible client to our API and start inferring.
Just change two lines — the base URL and API key. Your existing code, tools, and frameworks work instantly.
Use the official openai package.
Works with LangChain, LlamaIndex, and any OpenAI-compatible framework.
from openai import OpenAI client = OpenAI( base_url="https://proxy.trustedrails.com/v1", api_key="tr-prx-YOUR_KEY_HERE" ) response = client.chat.completions.create( model="Qwen/Qwen3-235B-A22B-Instruct-2507-FP8", messages=[{"role": "user", "content": "Hello!"}] )
Use the official openai npm package.
Works with Node.js, Deno, Bun, and browser environments.
import OpenAI from "openai"; const client = new OpenAI({ baseURL: "https://proxy.trustedrails.com/v1", apiKey: "tr-prx-YOUR_KEY_HERE", }); const response = await client.chat.completions.create({ model: "Qwen/Qwen3-235B-A22B-Instruct-2507-FP8", messages: [{ role: "user", content: "Hello!" }], });
Also works with Cursor, Continue, LibreChat, and any tool that supports a custom OpenAI endpoint.

and others
Point any OpenAI-compatible client to TrustedRails and get instant access to open-source models at low cost. No custom SDKs, no code rewrites.
Python, JavaScript, Go — just change base_url and api_key.
Cursor, Continue, LibreChat, and any app with a custom OpenAI endpoint setting.
LangChain, LlamaIndex, and other libraries that use the OpenAI API format.
When you use OpenAI or Anthropic directly, your prompts pass through their infrastructure. With TrustedRails, inference runs on distributed independent operators — no single party sees your complete data.
End-to-end encryption is on our roadmap — guaranteeing that no one, not even infrastructure operators, can access your data in transit.
Open-source models, transparent pricing, your data under your control.
