How this service works
Returns a 6-factor A-F risk grade for one market_id from in-memory caches only: no DB, no upstream call, no write. Market data is up to ~60s stale; order-book depth covers only the top ~100 Polymarket markets, so most ids (and all Kalshi) score with placeholder spread/category factors. Unknown id is 404, but a placeholder-heavy score still returns 200 and bills.
Output
A JSON object containing: the market_id and question text, a letter grade from A (low risk) to F (high risk), an integer overall_score from 0–100 (higher = riskier), and six named factor objects each with a score (0–100), weight (fixed per factor, all six sum to 1), and a human-readable reason string. Also includes a warnings array of threshold-triggered sentences (empty if none apply). Data is served from in-memory cache, up to ~60 seconds stale; order-book depth covers only the top ~100 Polymarket markets, so spread and category factors may use placeholders for other markets.
Example use cases
Pre-trade risk check on Polymarket
“Before I put money on this Polymarket market — condition ID 0xabc123 — can you pull its risk grade and tell me if there are any warnings about liquidity or resolution clarity?”
Screening high-risk prediction markets
“I'm building a watchlist and want to avoid anything graded D or F. Can you check the risk score for Polymarket market 0xdeadbeef and tell me the overall score and which factors are dragging it down?”
Comparing spread and category risk factors
“Get me the risk breakdown for Polymarket condition 0x9f8e7d — specifically the spread and category risk scores — so I can decide whether the odds are worth the risk.”

Endpoint
GEThttps://api.scanna.xyz/risk-scoreWhen to prefer
Choose this endpoint when you need a fast, structured, multi-factor risk grade for a specific Polymarket market and do not need real-time order-book data or write operations. It is ideal for pre-trade screening, automated risk filtering, or dashboards where sub-60-second staleness is acceptable. Avoid it for Kalshi markets (spread/category factors will be placeholders) or markets outside the top ~100 Polymarket listings if accurate spread scoring is critical.
Side effects
- 400 Bad Request if market_id query parameter is absent
- 404 market_not_found if the market_id is not in the live in-memory cache
- 200 returned with placeholder-heavy scores for markets outside the top ~100 Polymarket order-book coverage — still billed at $0.02001
- All Kalshi market IDs will return placeholder spread and category factors (no Kalshi order-book data)
- Scores can be up to ~60 seconds stale due to cache-only architecture
