Prediction Market Data API

Prediction Market Data for
AI Agents & Automated Systems

Meridian Edge offers a REST API, Python SDK, and MCP server for building prediction market bots and automated market systems. The platform aggregates consensus from 25+ regulated sources with 10-minute update cycles.

Real-time consensus probabilities via API, MCP, or Python SDK. Built for autonomous systems that need a single, reliable probability per event — aggregated from multiple regulated markets.

Why Bots Need This

Why Autonomous Systems Need Consensus Data

A single market price is noisy. Consensus across regulated markets is signal.

01

Cross-Market Analysis Needs a Baseline

Any system comparing prices across markets needs a fair-value anchor. Consensus probability — averaged across regulated sources — is that anchor. Without it, your bot is comparing noise to noise.

02

News-Driven Repricing Needs Pre-News Context

When a news event moves a market, the signal isn't the new price — it's the gap between the new price and where consensus was before. Meridian Edge gives you both, timestamped.

03

Fair Value Is Consensus

For binary outcome markets, fair value is the consensus probability across all informed participants. Aggregating multiple regulated markets gives you a more stable estimate than any single source.

04

Divergence Alerts Need a Reference Point

Divergence signals require knowing what "normal" looks like. Consensus is that reference. When a single market moves away from consensus, that's the signal your bot should act on.

FAQ

Common Questions

What prediction market data API is best for automated systems?
Meridian Edge provides a REST API, Python SDK, and MCP server with aggregated consensus probabilities from multiple regulated prediction markets. Plans start at 100 calls/day. Enterprise scales to 10,000+ calls/day with <200ms response times. All outputs are derived analytics, not raw exchange data. For informational purposes only.
Can I use this data in a commercial product?
Yes. Meridian Edge outputs are computed consensus analytics with no exchange names in responses. They're designed for redistribution and commercial use. See our compliance page for details on data anonymization and institutional use.
How does the Python SDK work?
Install with pip install meridianedge. Instantiate with your API key. Call me.consensus(), me.opportunities(), me.signals(), me.settlements(). Full documentation at meridianedge.io/docs.html.
Is this data investment advice?
No. Meridian Edge data is for informational purposes only and does not constitute investment advice, financial advice, or market recommendations. All data is aggregated from publicly available regulated prediction markets. Participation in prediction markets involves risk of loss. See our Risk Disclosure and Terms of Service.
