Beatpoly API

Prediction-market intelligence
through one reliability API.

The Beatpoly API enriches raw prediction-market data with reliability scores, resolution-risk analysis, liquidity-quality metrics, cross-venue equivalence, and abnormal-flow alerts. Use it to monitor markets, evaluate signals, and build products on top of trustworthy event-contract intelligence.

What the API provides

Not another raw odds feed.

Raw prediction-market APIs already expose markets, prices, order books, trades, and user activity. Kalshi and Polymarket both provide venue APIs for market data and execution.

Beatpoly adds the layer professional teams need before acting on that data: reliability, risk, and explainability.

Example response

Example market reliability response

Every reliability response includes the four dimension scores, a composite rating, human-readable key risks, and an evidence trail showing exactly how each score was derived.

The response is structured for integration into dashboards, risk systems, research pipelines, and automated monitoring workflows.

FAQ

Common questions

Is Beatpoly a replacement for Polymarket or Kalshi APIs?+

No. Beatpoly is an intelligence layer that enriches prediction-market data with reliability, risk, and market-quality analysis. It works alongside venue APIs. The venue API gives you the raw market data. Beatpoly tells you whether that data is trustworthy enough to act on.

Does the API support real-time alerts?+

The API is designed to support abnormal-flow alerts, integrity flags, and market-monitoring workflows. Access levels and update frequencies may vary by customer and coverage requirements — discuss your needs in the access request form.

Can Beatpoly score custom watchlists?+

Yes. Enterprise customers can request monitoring for specific markets, categories, venues, or event types. Custom watchlists are discussed during the access scoping process.

What data does Beatpoly use to generate scores?+

Beatpoly uses publicly available market data, contract wording, resolution documentation, order-book activity, and on-chain data for Polymarket. The scoring methodology is documented on the methodology page. We do not use private or non-public information.
