Prediction Market Aggregator

Cross-market prediction data, edge detection, and arbitrage scanner. Open-source alternative to DomeAPI.

Markets Covered

Market	Assets	API	Auth
Polymarket	BTC, ETH, SOL, XRP hourly + major events	CLOB REST	API key + EIP-712
Manifold Markets	Thousands of community markets	REST	API key (free)
Metaculus	Long-form forecasts, aggregated consensus	REST	None (public)
Kalshi	US-regulated binary contracts	REST	API key

Core Features

1. Cross-Market Arbitrage Scanner

Find the same question priced differently across markets:

BTC >$70k by March? 
  Polymarket: 62% 
  Manifold: 71%  ← 9% gap → sell Manifold, buy Polymarket
  Metaculus: 58%

2. Consensus Drift Detection

Track how market consensus shifts over time:

Alert when market moves >10% within 30 minutes
Detect smart money vs retail flow divergence
Flag markets where Metaculus (superforecasters) disagrees >15% with Polymarket

3. Polymarket CLOB Integration

Full py-clob-client compatible:

Scan hourly BTC/ETH/SOL/XRP markets
Calculate edge vs TA-implied probability (Argus strategy)
Counter-consensus detection (L023): market >70% one-sided + TA disagrees = bet

4. Unified API Response Format

{
  "question": "BTC up by 1pm ET?",
  "markets": {
    "polymarket": { "yes": 0.62, "volume": 455000, "url": "..." },
    "manifold": { "yes": 0.71, "traders": 142, "url": "..." }
  },
  "arbitrage": { "detected": true, "gap": 0.09, "direction": "buy_poly_sell_manifold" },
  "consensus": { "weighted_avg": 0.65, "superforecaster_avg": 0.58 }
}

How to Use

Ask: "Is there arbitrage between Polymarket and Manifold on BTC price?" Ask: "What markets have the widest consensus gap right now?" Ask: "Find me the highest-edge Polymarket bet using cross-market consensus"

DomeAPI Migration Guide

If you used DomeAPI for cross-market data:

/v1/markets → Use Polymarket CLOB /markets + Manifold /v0/markets + Metaculus /questions
/v1/arbitrage → Use this skill's cross-market scanner
/v1/consensus → Use Metaculus community predictions as consensus baseline

Argus Integration

This skill plugs directly into the Argus edge detection strategy:

Get TA score from argus-edge skill
Compare vs cross-market consensus from this skill
If TA + consensus both diverge from Polymarket price → max conviction bet
