How this service works
One market_id in, one live CatBoost probability out, plus market_price, divergence and a ~28-field feature snapshot. Features come from the worker-maintained DB serving state, not request-time compute, and snapshot_at is stamped at request time, so stale state looks fresh. Confidence band often nulls to unavailable. No empty 200: missing data is a 404.
Output
A JSON object containing the market_id, predicted probability, current YES market price, divergence (predicted minus market price, to 3 decimal places), divergence_pp (same in percentage points, 1dp), confidence_low and confidence_high (or confidence_band='unavailable' when no real interval exists), prediction_status ('provisional' or 'canonical_enforced'), model_source, feature_count, and a features_snapshot object with ~28 raw feature values stamped at request time. Returns 404 if the market is not in the live cache or has fewer than 5 trades; 400 if market_id is absent.
Example use cases
Spotting mispriced prediction markets
“Check the Scanna live prediction for Polymarket market 0xabc123 — I want to know the model's probability versus the current market price and how big the divergence is.”
Pre-trade model sanity check
“Before I place a bet on Polymarket condition 0xdef456, can you pull the Scanna live prediction and show me the confidence band, predicted probability, and what features the model used?”
Automated arbitrage signal monitoring
“Fetch the Scanna live-predict score for Polymarket condition 0x789xyz and tell me the divergence in percentage points so I can decide if it's worth trading.”

Endpoint
GEThttps://api.scanna.xyz/live-predictWhen to prefer
Use this endpoint when you need a machine-learning-derived probability estimate for a specific active Polymarket market alongside its current market price and divergence signal in a single call. Prefer this over the risk-grade endpoint when you need a numeric probability rather than a letter grade, or when you want the raw feature snapshot for further analysis. Best suited for trading signal generation, mispricing detection, or pre-trade model validation on individual markets.
Side effects
- 404 market_not_found: market_id is valid but not in the live worker cache
- 404 insufficient_data: market has fewer than 5 trades and cannot be scored
- 400: market_id query parameter is absent
- confidence_band='unavailable': confidence interval could not be computed, confidence_low/high will be null
- features_snapshot may reflect stale worker DB state even though snapshot_at is request time
- Divergence and divergence_pp fields are omitted entirely when either predicted probability or market_price is missing
