An API key is all you need. Works with all agents and tools you already use.

radion-quickstart.md

Set up Radion on this machine. Add the Radion's documentation MCP with: `npx add-mcp https://docs.radion.app/mcp` or use `https://docs.radion.app/llms.txt` as a fallback.

Set my API key as a local environment variable: `export RADION_API_KEY=<your-key>` (or add to .env).

**IMPORTANT: Never paste the API key into conversations, prompts, or logs - it's a secret credential and educate me about how to keep it secure but keep it brief.**

Once set up, explore the documentation to understand all available endpoints and capabilities, then explain everything I can do with the Radion API: endpoints, data types, and showcase some interesting data insights I can get.

Paste into Claude Code, Cursor, or any coding agent.

Common questions.

Where does the signal come from?

Radion pulls from Polymarket's API and on-chain transaction data. We ingest, clean, and run it through our proprietary scoring model. You get a structured signal, not raw market noise.

How is this different from querying Polymarket directly?

Polymarket's API gives you market prices. Radion gives you the gap between what the crowd prices and where qualified on-chain wallets are actually positioned, plus a confidence score on every read. The ingestion pipeline, wallet qualification logic, and scoring model are all ours.

How current is the data?

Signals are refreshed daily across the highest-volume markets, ranked by volume. On-demand analysis for any market will be available on premium plans.

How do I know when to trust a signal?

Every signal includes a confidence score derived from sample size and wallet quality. Coverage is exhaustive within what the on-chain data exposes. We don't estimate or interpolate. Low confidence means fewer qualifying wallets on that market; size your position accordingly.

What markets are covered?

Radion covers the most popular Polymarket markets ranked by volume. Coverage grows as markets gain liquidity.
