What OneInterface Does
One control plane for model access, routing, and spend.
Instead of wiring every provider separately, One Interface gives your app and coding tools a single place to call models, switch routing profiles, and see what everything costs.
One key for 200+ models
Use OpenAI, Claude, Gemini, xAI, and specialist models through one OpenAI-compatible endpoint.
Task-aware model routing
Pick fast, balanced, or frontier coding profiles, then route requests without rebuilding your app.
Unified billing and pricing
Track usage across providers in one console with pay-as-you-go credits and no provider-by-provider invoices.
Works with coding tools
Connect Claude Code, Cursor, Codex, or any tool that supports a custom OpenAI-compatible base URL.
Drop-in migration
Change your base URL and API key, keep the rest of your existing SDK code almost exactly the same.
Controls for teams
Centralize API keys, spend visibility, and provider access so product teams can move without losing oversight.
Setup
Use any model from the same client.
// OpenAI-compatible client
const client = new OpenAI({
apiKey: process.env.ONEINTERFACE_KEY,
baseURL: "https://api.oneinterface.ai/v1"
});
await client.chat.completions.create({
model: "coding-balanced",
messages: messages
});Supported Providers

All AI providers.
Your application connects to a single endpoint. We route each request to the right provider, at the best rate.
