Opinion vs Polymarket ARB monitor

This bot uses exchange APIs only (no web-page scraping):

• Opinion API: GET {base_url}{orderbook_path}?topicId=...&outcomeId=...
• Polymarket CLOB API: GET https://clob.polymarket.com/book?token_id=...

It checks both sides for arbitrage:

• if Opinion best bid > Polymarket best ask => BOOM
• if Polymarket best bid > Opinion best ask => BOOM

Alerts are sent to:

• Telegram
• local dashboard (http://localhost:8080)

Setup

export TELEGRAM_BOT_TOKEN='8331830301:AAFUCwAEyQwVZsCdzelOSQ3008QQeVvg6Gw'
export TELEGRAM_CHAT_ID='6645079982'
export OPINION_API_KEY='...'
python app.py --config config.json

Important config fields

• pairs[].opinion.topic_id (already set to 332)
• pairs[].opinion.outcome_id (must be exact outcome in Opinion market)
• pairs[].polymarket.token_id (must be exact CLOB token id for that Polymarket outcome)

Extending later (Predict.fun, more markets)

Add additional objects under pairs. The engine is pair-based and reuses the same arb + alert pipeline.

WS vs REST

Polymarket config includes ws_url and use_ws for future live stream mode. Current default is REST polling for reliability.
