Is this a real integration or just a base-URL swap?

Mostly a swap. The guide's substance is pointing @typesafe-ai/sdk or typesafe_sdk at OpenRouter's API base with an OpenRouter key, and letting System One models bill to your OpenRouter account. Questions and confidence semantics stay on TypeSafe's own docs.

Will the SDK break against OpenRouter's response shape?

Yes, in one documented place. The guide flags that the SDK rejects the shape returned by client.models.list(), because OpenRouter's models API does not match what the TypeSafe SDK expects. That is a rough edge to code around rather than a clean drop-in.

Do I have to rewrite model ids to use it?

Bare ids such as jev-1.13 are mapped onto the vendor's namespace before routing, so short names are handled for you. The reverse is not promised, which matters if you move between OpenRouter and the vendor's own endpoint.

Does this tell me how to write a question or set a cut-off?

No, and the entry copy says so. This page covers the routing mechanics, and the response adds fields the SDKs pass straight through. Deciding what a good question looks like and what confidence means is documented elsewhere.

Which environment variables configure the SDK against OpenRouter?

Set TYPESAFE_BASE_URL=https://openrouter.ai/api and TYPESAFE_API_KEY to your OpenRouter key to leave the constructor unchanged, or pass apiKey plus baseURL directly. The SDK appends /v1/systemone, so requests land on https://openrouter.ai/api/v1/systemone.

Do I have to use the TypeSafe SDK to reach Jev here?

No. You can call the Decisions API directly or through OpenRouter's own TypeScript, Python, or Go SDK instead. The Jev tutorial walks that path from the first request through to making a threshold decision.

What does the jev-latest id resolve to on OpenRouter?

It routes as ~typesafe/jev-latest, OpenRouter's alias for the newest Jev release, while a bare jev-1.13 is mapped to typesafe/jev-1.13. IDs that already carry an author prefix are used as-is, and the response model field shows the OpenRouter ID that served it.

Highlights

Covers @typesafe-ai/sdk and typesafe_sdk. Set the base URL to https://openrouter.ai/api and pass an OpenRouter key.
Bare ids such as jev-1.13 are mapped onto the typesafe/ namespace before routing.
client.models.list() hits OpenRouter's models API, and the TypeSafe SDK rejects that response shape.
Responses add id, provider, and usage.cost. The SDKs pass those fields through.

Watch out

A routing guide. How to write questions, and what confidence means, stays on TypeSafe's docs.
