How this service works
Per-market Polymarket taker-flow concentration, price-band structure and book compatibility. Facts, never a fraud verdict. BEFORE YOU PAY: free substitute https://dash.polym.uk/markets.json. THIS ADDS: A single-market lookup instead of the whole snapshot, for a decomposed market. Outside that set: 422, and no charge.
Output
A JSON object containing factual per-market signals including taker-flow concentration metrics, price-band structure breakdown, order book compatibility scores, and historical resolution base-rate context for the specified Polymarket condition. No fraud verdict or predictive signal is included — output is purely descriptive and structural.
Example use cases
Pre-trade market structure check
“Before I trade on this Polymarket market — condition ID 0xdef456 — can you pull the taker-flow concentration and book compatibility metrics so I know if the market looks structurally healthy?”
Resolution base-rate research
“I'm researching Polymarket markets in the politics category. Can you get me the resolution base-rate context and price-band structure for condition ID 0x789abc?”
Automated market screening alert
“For my trading bot, check condition ID 0x123def on Polymarket and give me the taker-flow concentration score and book compatibility data so I can decide whether to include it in my watchlist.”
Technical details
Endpoint
GEThttps://api.polym.uk/market-authenticity/:conditionIdWhen to prefer
Use this endpoint when you need factual, structural microstructure data for a specific Polymarket market — particularly taker-flow concentration and book compatibility — rather than a subjective fraud verdict or directional price prediction. Prefer this over general prediction market APIs when you need resolution base-rate context grounded in historical UMA resolution patterns specific to Polymarket.
Side effects
- Invalid or unknown conditionId returns a 404 or empty result
- Condition ID referencing a market with insufficient trade history may return sparse or null concentration fields
- Network timeouts if Polymarket data feed is temporarily unavailable
- Malformed conditionId format may return a 400 validation error
