Vast.ai Python SDK — high-level API for GPU instances, volumes, serverless endpoints, and billing.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Vast.ai Python SDK (`vastai` / `vastai_sdk`)

The `vastai` package provides a Python SDK for managing GPU instances, volumes, serverless endpoints, and billing on Vast.ai. The `vastai_sdk` package is a backward-compatibility shim that re-exports `vastai`.

## Installation

```bash
pip install vastai
```

For serverless and async support:
```bash
pip install "vastai[serverless]"
```

## Authentication

The SDK reads the API key from `~/.vast_api_key` by default. You can also pass it explicitly:

```python
from vastai import VastAI
vast = VastAI()                        # reads ~/.vast_api_key
vast = VastAI(api_key="YOUR_API_KEY")  # explicit key
```

Get your API key from https://console.vast.ai/manage-keys/

## Backward Compatibility

The old `vastai_sdk` import still works:

```python
from vastai_sdk import VastAI  # equivalent to: from vastai import VastAI
```

## VastAI Class (High-Level SDK)

```python
from vastai import VastAI
vast = VastAI(api_key=None, server_url=None, retry=3, raw=False, quiet=False)
```

### Instance Management

```python
# List all your instances
instances = vast.show_instances()

# Get a single instance
instance = vast.show_instance(id=12345)
…

How to install

The exact contents, by fingerprint

mdr add vast-ai/vast-cli/vastai-sdk@sha256:40d5d51eacbaf0f3

The line at the top of this page pins the label git:20260826.ecf32ef, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
