Three quick helpers for predict.fun: work out the exact fee on any order, estimate the Predict Points you'd earn, and see whether the API and WebSocket are healthy right now. All read-only — no wallet, no keys.
predict's base is 200 bps (2%). Fetch a market's exact rate on the status tab.
Takers pay fee = feeRate × min(price, 1−price) × shares, charged in USDT. It's symmetric around 0.50, so the closer the price is to a coin-flip the more you pay in absolute terms, while the effective % of your money grows as the price gets cheaper. Makers pay nothing. There's a $1 minimum order value. A 10% discount, when active, just multiplies the fee by 0.9.
Paste a wallet and pick a window — it reads your on-chain fills and sums the real fees you paid across all predict exchanges. Addresses only, read-only.
Addresses only — never a private key or seed phrase. Reads public on-chain data; it can't move funds and never asks for a key. A very active wallet over a long window may be capped by the time budget (it'll say so).
Predict publishes the liquidity model: markets show a PP/hr rate (a 1–5 star tier), rewards are shared pro-rata among eligible resting orders, and paid weekly (allow 5–6 days after each week closes). To qualify you need a minimum order size, orders on both sides, and spreads inside the market's threshold — tighter spreads earn more, so treat the liquidity figure as an upper-ish estimate for a well-placed quote. Predict does not publish a points-per-dollar rate for plain trading, so that field is your own assumption. Referral is documented: you earn 10% of your referrals' points, in perpetuity.
probing…
Probes run from this server (Europe), so latency reflects the EU→predict path, not your own. predict's API is served through Cloudflare from an Asia-region origin, so users far from Asia normally see higher round-trips — that's location, not an outage. Rate limit shows what predict returned on the probe (their public limit is around 240 requests/min per key). Chain freshness is the age of the latest BNB block as seen through our RPC — a good staleness cross-check. Results are cached ~10s so this page can't be used to hammer predict.
