# Arbitrage: Cross-Platform Prediction Market Intelligence

> Arbitrage aggregates prediction markets from 7 venues into a unified index, detects real-time arbitrage, and exposes everything via a clean REST API.

Arbitrage gives you a single API to access prediction markets from Polymarket, Limitless, Predict.fun, Manifold, PredictIt, Azuro, and Drift. It normalizes prices across all venues, detects cross-platform arbitrage opportunities with fee-adjusted scoring, and tracks wallet positions — so you can build trading tools, research dashboards, or automated strategies without managing seven separate integrations.

## What Arbitrage does

Arbitrage continuously ingests market data from seven integrated prediction market venues, links equivalent questions across platforms using semantic embeddings, and detects when the same outcome is priced differently — giving you actionable arbitrage intelligence with lifecycle tracking and execution-quality scores.

## Get started in 3 steps

<Steps>
  <Step title="Create a developer account">
    Register at [app.revalonlabs.xyz](https://app.revalonlabs.xyz) or call `POST /api/v1/auth/register` with your email and password. This gives you access to the Developer Console.
  </Step>

  <Step title="Generate an API key">
    Open the [Developer Console](/console/overview), navigate to **API Keys**, and create a new key. Your key is prefixed with `pdx_` and shown only once — store it securely.
  </Step>

  <Step title="Make your first request">
    Pass your key in the `X-API-Key` header to start fetching arbitrage opportunities and market data.

    ```bash theme={null}
    curl https://api.predexy.com/api/v1/external/arbitrage/opportunities \
      -H "X-API-Key: pdx_your_key_here"
    ```
