✓ Same tool call and required identifier in the verified test.

One measured test, not a guaranteed average. Results vary by workload.

Integration takes minutes

OpenAI-compatible applications change their API base URL and use a Varion key. The rest of the application can remain the same.

1

Create an account

Receive 500 Varion credits after email verification and test before connecting production traffic.

Run a no-code or local test

Use the browser Test Lab or download Python, Node.js, cURL and OpenClaw testers.

3

Connect production

Replace the API base URL, keep your provider account under your control and track measured savings.

Common questions

Does Varion guarantee a fixed savings percentage?

No. Every workload is different. Customers can test their own prompts and requests before using production traffic.

Does Varion pay my provider bill?

No. Customers keep their own provider account. Varion credits cover only Varion fees.

Do you store provider keys used in local testers?

No. Local testers keep OpenAI or Claude keys on the customer’s computer. Only metrics are uploaded when the customer chooses.

What happens when optimisation may be unsafe?

Varion can pass the original request through unchanged. Unverified workflows default to passthrough.

Can non-coders test Varion?

Yes. The customer dashboard includes no-code prompt, history, schema, file, token and savings tools.
