FAQ
Data freshness, P&L differences, licensing, and the usual questions.
How fresh is the data?
Trades land from the chain within seconds (the live pulse and WSS feeds are real-time). Heavy metric recomputes (windowed metrics, percentiles, rankings) run nightly. Each cached public response carries a snapshot-age header.
Why does a trader's P&L differ from another tracker?
Polyrank reproduces Polymarket's own methodology — average-cost basis,
sell-clamping, peer transfers ignored, LP rewards excluded — and validates
it at scale against on-chain events. Trackers using FIFO, including
transfers, or counting rewards will differ. When our reconciliation flags a
wallet, we show pnl_under_review rather than a number we can't stand
behind.
Where does the data come from?
Public Polygon on-chain events (CTF Exchange fills, splits/merges, redemptions, resolutions) indexed end-to-end — including maker-side fills, which most trackers miss. Every number traces to a transaction.
Can I use the API in a browser app?
Yes — /v1/public/* sends permissive CORS and needs no credentials. The
authed API is CORS-restricted to polyrank.app; call it from your backend
with an API key instead.
What can I do with the data? (licensing)
Free public API: personal and evaluation use with attribution ("data: polyrank.app"). Paid plans license internal/commercial use scaled by tier; redistribution of bulk data requires Desk or Enterprise. Details: polyrank.app/tos.
Is this investment advice?
No. Polyrank is read-only analytics over public data. Most prediction-market traders lose money; past calibration does not guarantee future calibration.
Is Polyrank affiliated with Polymarket?
No. Independent, read-only, non-custodial.
