# Radion Docs

> Polymarket data from Radion's own on-chain indexer. Read markets, events, search, and order books.

Radion is an API for Polymarket data. We run our own on-chain indexer. We read Polymarket's smart contracts straight from the blockchain and turn the raw events into clean, ready-to-use data. You get markets, events, search, and orderbooks — all from one place.

## How it works

<Steps>
  <Step title="Read the chain">
    We watch Polymarket's smart contracts on Polygon. Every trade, position
    change, and market event is read straight from the blockchain.
  </Step>

  <Step title="Build clean data">
    We turn the raw chain events into a tidy read model: markets, events,
    search, and order books. No raw logs to parse yourself.
  </Step>

  <Step title="Read via API">
    Pull the data with the REST API, or stream it live over WebSockets. Use it
    in your tools, dashboards, or bots.
