# Introduction

> Query premium datasets from your AI agents and applications

# What is Datagate?

Datagate is a data marketplace that connects AI agents to premium datasets. Sellers publish vector-indexed datasets, and buyers query across them via a single API call.

**For AI agent builders**, Datagate provides:

* **One API** to search across multiple sellers' datasets simultaneously
* **Automatic embedding** — send natural language, the server handles vectorization
* **Cross-model search** — query datasets using different embedding models in a single call
* **Metadata filtering** — filter results per-dataset using MongoDB-style operators
* **Pay-per-chunk pricing** — only pay for the results you receive

## How it works

```
Your Agent → POST /v1/query → Datagate → Fan-out to seller vector DBs → Merge & rank → Results
```

1. **Discover** datasets with `list_datasets()` — see what's available, pricing, and filterable fields
2. **Query** with `query()` — send natural language text, get ranked results with metadata
3. **Pay per chunk** — each result chunk is billed at the dataset's price (typically fractions of a cent)

## Two ways to integrate

**SDK** — use Datagate directly in your code. Returns typed objects, full control over error handling.

```bash theme={null}
pip install datagate     # Python
npm install datagate     # TypeScript
```

**MCP server** — connects Datagate to Claude Desktop, Claude Code, or any MCP-compatible agent. No code needed — the AI agent discovers and calls the tools automatically. The MCP server uses the SDK under the hood.

```bash theme={null}
pip install datagate-mcp     # Python
npm install @datagate/mcp    # TypeScript
```
