How this service works
Cross-venue matched market clusters from Postgres: cluster row, member markets with outcomes, optional related/raw edges. LIMIT/OFFSET pushed into SQL (max 100). Served matches are LLM-verified and stay valid, but COVERAGE can be incomplete: adjudication is a separate gated step and while paused no new match is promoted - see `freshness`. An empty page is a billable 200.
Output
A paginated JSON response containing an array of cluster objects, each with a cluster_id, canonical_title, category, LLM-verified confidence score, 24-hour volume, updated_at timestamp, verified flag, relations array, and a members array of constituent markets with their outcomes. Also returns total count (capped at 10000), limit, offset, updated_at, and a freshness object indicating adjudication status. Optionally includes related[] and raw_edges[] arrays.
Example use cases
Arbitrage opportunity discovery across platforms
“Find me matched market clusters that exist on both Polymarket and Kalshi with confidence above 0.85 — I want to spot markets where the same event is priced differently across venues.”
Deep dive on a specific prediction market
“Pull all cross-venue clusters anchored to market UUID 'b3f1a2c4-5678-90ab-cdef-1234567890ab', including raw edges and related markets, so I can see every equivalent question across venues.”
Monitoring high-volume cross-venue clusters
“Give me the first 50 matched market clusters across all venues sorted by 24-hour volume, with related markets included, so I can track where the most trading activity is happening right now.”
Technical details
Endpoint
GEThttps://api.scanna.xyz/matched-market-clustersWhen to prefer
Use this endpoint when you need to find equivalent prediction markets across multiple venues (Polymarket, Kalshi, Limitless, etc.) that cover the same underlying event. It is ideal for cross-venue arbitrage detection, market coverage analysis, or building unified views of prediction market activity. Prefer this over single-venue market feeds when cross-platform market matching with LLM verification and confidence scoring is required. Use the anchor_market_id parameter to pivot from a known market to its cross-venue equivalents.
Side effects
- 400 error if limit/offset is out of range or a non-digit value is passed for numeric parameters
- 400 error if an invalid venue enum value is provided
- Empty page (0 clusters) returned as a billable 200 when no clusters match filters or coverage is incomplete due to paused adjudication
- Incomplete coverage: new matches may not be promoted if adjudication is paused — freshness field signals this state
- min_confidence must be a digit-led decimal; non-digit values return 400
