# LiteLLM

> Bring LiteLLM gateway cost into CostGraph, pulled by us or pushed by you

LiteLLM is a self-hosted gateway that fronts many LLM providers behind one proxy
and tracks the spend of every request it routes.

CostGraph reads LiteLLM as **FOCUS 1.2** records at a grain of one record per day
per model per virtual key.

## Choose how the data reaches us

<CardGroup cols={2}>
  <Card title="CostGraph pulls it" icon="cloud-arrow-down">
    You supply read-only credentials and we call LiteLLM once a day. Nothing to run.
  </Card>

  <Card title="You push it" icon="cloud-arrow-up">
    You send us FOCUS records over the API. Credentials never leave your infrastructure.
  </Card>
</CardGroup>

## Let CostGraph pull

1. Open **Settings -> Integrations** and pick **LiteLLM**.
2. Name the connection and pick the tenant these charges belong to.
3. Fill in the values the form asks for. It lists exactly the variables LiteLLM
   needs, marks which are optional, and explains the permission each one requires.
4. Select **Connect**.

CostGraph verifies the credentials with a short fetch before saving, so a wrong
value or a missing permission fails while you are still on the form.

<Note>
  Credentials are encrypted at rest and used only to read billing data. Revoke them in
  LiteLLM at any time and the connection stops; nothing else is affected.
</Note>

## Push it yourself

Send the charges to CostGraph as FOCUS records instead. [Push FOCUS data](/costgraph/integrations/focus-push) covers the connection id,
the `focus:write` key, and the request shape.

## What CostGraph does with it

Records land as raw billing rows, are normalised into line items, and roll up into
daily cost. From there LiteLLM spend appears in Cost Overview and in anomaly
detection alongside every other provider, with spend attributed back to the
virtual key or team that incurred it.
