Output
An ordered list of Polymarket prediction markets ranked by relevance to the input headline, each containing: market title, live odds/implied probability, 24-hour odds drift, bid-ask spread, on-book liquidity, total trading volume, resolution date, and a direct bet link to execute the trade on Polymarket.
Example use cases
Breaking election news trade
“The headline just dropped: 'Biden withdraws from 2024 race' — what are the top Polymarket markets I can trade on this right now? Give me the live odds, 24h drift, and a bet link for the most liquid ones.”
Geopolitical event market discovery
“I'm seeing news that 'Ukraine and Russia agree to ceasefire talks' — find me the best-matching Polymarket prediction markets for this, ranked by relevance, with current implied probabilities and volume.”
Economic data release reaction
“The headline reads 'US CPI comes in hotter than expected at 4.2%' — show me the Polymarket markets most relevant to trade on this, with spread, on-book liquidity, and resolution dates.”
Technical details
Endpoint
POSThttps://outcomescout.vercel.app/api/v1/news-to-marketsWhen to prefer
Use this endpoint when a trading agent needs to instantly map a breaking news headline to actionable Polymarket prediction markets with live market data. Prefer it over manual Polymarket search when speed matters, when building automated news-to-trade pipelines, or when you need structured market metadata (odds, liquidity, spread) in a single call rather than scraping the Polymarket UI.
Side effects
- No matching markets found for obscure or very recent headlines
- Stale odds if Polymarket data feed is delayed
- Low liquidity markets returned for niche topics
- Ambiguous headlines may surface loosely related markets
- Rate limit or payment failure for the $0.01 USDC per-call fee
