# Vast.ai

> Bring Vast.ai GPU rental cost into CostGraph, pulled by us or pushed by you

Vast.ai is a marketplace for renting GPU machines. Each instance and volume bills
for GPU time, storage, and bandwidth.

CostGraph reads Vast.ai as **FOCUS 1.2** records at a grain of one record per
instance or volume per charge type per day.

## 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 Vast.ai 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>

## Before you begin

* In the Vast.ai console, open **Keys** and create an API key on the account that
  rents the instances.
* The connect form links to the page where you create this key.

## Let CostGraph pull

1. Open **Settings > Integrations** and pick **Vast.ai**.
2. Name the connection and pick the tenant these charges belong to.
3. Enter the values you copied. The form lists what Vast.ai needs and marks the
   optional ones.
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
  Vast.ai 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.

## Run the exporter

Rather than build that request yourself, run our exporter. It reads Vast.ai on a
schedule and pushes the records for you, wherever you want to run it: a container, a
Kubernetes `CronJob`, or a binary on a machine you already have.

```bash theme={null}
focus-exporter --provider vast --sink costgraph
```

Your Vast.ai credential stays where you put it, and only the finished FOCUS records
reach CostGraph. [Run the exporter](/costgraph/integrations/exporter) covers the three
ways to run it and the variables it reads.

## What CostGraph does with it

Records land as raw billing rows, are normalised into line items, and roll up into
daily cost. From there Vast.ai spend appears in Cost Overview and in anomaly detection
alongside every other provider. GPU, storage, and bandwidth sit on separate lines, so
storage you are still paying for after the work has finished stands out.
