How this service works
Serves the in-memory Polymarket+Kalshi market universe (worker-refreshed ~60s; up to 5 min stale before the gate 503s). Filters and sorts the WHOLE cached universe by volume_24h, then slices: limit trims output, not work. Zero DB and zero upstream calls in the request path. Empty pages (filters matching nothing, cursor past end) return 200 and are billable.
Output
A JSON object containing an array of market objects (question, condition_id, slug, platform, outcome prices, active/closed flags, volume_24h, volume_total, liquidity, end_date, tags, winning_side), plus page metadata: count (rows in this page), total (matches before cursor slice), updated_at (cache timestamp), next_cursor (for pagination), and optional _meta upsell pointers.
Example use cases
Monitor top election prediction markets
“Pull the top 50 prediction markets tagged 'elections' across both Polymarket and Kalshi with at least $1000 in 24h volume — I want to see what's moving today.”
Browse Kalshi-only crypto markets
“List up to 200 active Kalshi markets in the crypto category, sorted by 24h volume, so I can see which ones are getting the most action right now.”
Paginate full market universe for analysis
“Fetch all prediction markets across Polymarket and Kalshi in batches of 500, starting from the beginning, so I can build a comprehensive snapshot of the entire market universe.”
Technical details
Endpoint
GEThttps://api.scanna.xyz/marketsWhen to prefer
Choose this endpoint when you need a broad, multi-venue view of prediction markets sorted by 24h volume without requiring real-time data (up to 5 min stale is acceptable). It is ideal for browsing, discovery, and filtering across the combined Polymarket+Kalshi universe in a single call. Prefer this over individual venue APIs when you want cross-platform aggregation, low-latency in-memory responses, and cursor-based pagination over large result sets. Not suitable when you need real-time prices for specific markets (use the prices endpoint) or trade history (use the trades endpoint).
Side effects
- 503 returned when cache is more than 5 minutes stale (worker down)
- Empty 200 response (count=0) when filters match no markets — still billable
- Cursor value unparseable — silently falls back to page 1 instead of erroring
- limit out of range is clamped silently (1–500), not rejected
- Platform values other than 'polymarket' or 'kalshi' are ignored, returning all platforms
