This guide takes you from zero to a traced LLM call on the hosted to11 platform.

1. Create your account

Sign up at app.to11.ai and create your first organization, workspace, and project. See Core Concepts for how those fit together.

2. Connect a provider

In your project, connect the model provider you want to use (OpenAI, Anthropic, xAI, and more) by adding its credential. The gateway uses it to reach the provider on your behalf. See Providers.

3. Create an API key

Open Settings → API keys and create a key scoped to what your application needs. Copy the secret — it’s shown only once. See API keys.

4. Point your SDK at the gateway

Change your SDK’s base URL to the to11 gateway at https://gw.to11.ai and authenticate to to11 with the x-to11-authorization header. Your provider key stays in the SDK’s api_key (the standard Authorization header), forwarded upstream — or omit it if you configured the provider credential in your project above.

5. Read the gateway’s response id

Every gateway response carries an x-to11-request-id header — a unique id for the call you can log alongside your own records. The parsed SDK response object doesn’t expose headers, so read them with the SDK’s raw-response API:

6. See your trace

In the to11 dashboard, open your project and go to Traces. Your request shows up as a GenAI span — model, tokens, and latency — with no instrumentation code on your side.
