Get started

Three things. Then the P&L has rows.

  1. 01

    Copy your CostSlice key

    Keep your OpenAI API key. This is x-cs-key. It authenticates you to us, not the model.

  2. 02

    Change the base URL

    Point the SDK at https://api.costslice.com/v1 and send x-cs-key. Completions still go to OpenAI with your key.

  3. 03

    Tag tenant, feature, env

    Opaque ids. Forget a tag and the completion still returns. It lands in untagged.

We never store prompts or completions. Fail-open.
