How this service works
Returns yes/no prices for up to 50 condition_ids, read from an in-process market cache; no DB or upstream call. Prices are up to ~60s stale (updated_at is the cache refresh time). Unknown or long-tail ids return found:false with null prices in a 200, so an all-null response is still billable. 503 when the cache is not hydrated.
Output
A JSON array of price entries — one per requested condition ID in request order — each containing condition_id (echoed), found (boolean), price_yes (0–1 float or null), price_no (0–1 float or null), platform ('polymarket', 'kalshi', or null), plus a top-level count (number of IDs read, max 50) and updated_at (ISO timestamp of last cache refresh). Unknown IDs return found:false with null prices but are still included and still billable.
Example use cases
Real-time prediction market price check
“Can you pull the current yes and no prices for these five Polymarket condition IDs: 0xabc1, 0xdef2, 0xghi3, 0xjkl4, 0xmno5?”
Arbitrage opportunity detection
“I want to compare yes prices across these 20 condition IDs on Polymarket and Kalshi — can you fetch all their current prices so I can spot any discrepancies?”
Portfolio market price snapshot
“Get me the latest yes and no prices for all the prediction market condition IDs in my watchlist: 0xa1b2, 0xc3d4, 0xe5f6, 0xg7h8, 0xi9j0 — I need to know which ones Scanna actually has in its cache.”
Technical details
Endpoint
GEThttps://api.scanna.xyz/pricesWhen to prefer
Choose this endpoint when you need fast, low-latency yes/no price lookups for up to 50 prediction market condition IDs and can tolerate ~60s cache staleness. It is ideal for polling or repeated price checks where speed matters more than real-time accuracy. Prefer it over DB-backed alternatives when you need sub-second response times and don't need guaranteed freshness. Not suitable when you need guaranteed live prices, historical price data, or resolution outcomes.
Side effects
- 503 Service Unavailable when the in-process cache has not yet been hydrated after a cold start
- All prices null with found:false for unknown or long-tail condition IDs — response is still 200 and still billable
- Silent truncation of IDs beyond the first 50 — no error is returned for the discarded IDs
- Prices may be up to ~60 seconds stale relative to live market state
- Blank entries in the comma-separated ids string are silently dropped
