Prediction Markets x402 offerings

Real-time pre-trade signal: a probability snapshot of Hyperliquid's HIP-4 prediction markets - crypto price binaries, sports outcomes, tournament winners, Fed rate decisions, and more. Fields are parsed verbatim from Hyperliquid, so new market types appear automatically. Optional template/underlying filters narrow the result; limit caps rows (max 500). Subscribe to webhook alerts via GET /v1/prediction/hip4-alerts/subscribe. Paid in USDC on Base.

Detect basket arbitrage in a Polymarket neg-risk (mutually-exclusive, multi-outcome) event - since a full YES basket across all outcomes always settles to exactly $1, a basket price away from $1 is a near risk-free edge. Also computes buy/sell_basket_capacity_shares, the actual liquidity-bottleneck size executable right now, so this is not just a top-of-book mirage. Polymarket only (Kalshi's Data ToS forbids this use of their data). Paid in USDC on Base.

For bots that poll: crowd-state events (a perp entering or leaving a state) since a timestamp, newest first, up to 7 days back. Each event is signed with the mark price at the time. Not investment advice.

Every live Hyperliquid outcome (prediction) market: readable title, category (sports, price, ipo, policy_rate, awards), deadline, each side's price as implied probability with its 24h change, and 24h volume, most traded first. Filter with category and q (text search). On-chain data. Signed. Not investment advice.

One Hyperliquid outcome (prediction) market by id: readable title, structured details (teams, thresholds, deadlines, official source), each side's implied probability, 24h change, volume and outstanding value, its question, and a week of hourly prices per side. Ids come from /v1/outcomes/list. Signed. Not investment advice.

Cross-venue prediction-market search: one query returns a ranked list of NORMALIZED markets from Polymarket (real-money) and Manifold (play-money) under one schema — implied probability, outcomes, volume, liquidity, close date, status, money_type and a link-back. One call instead of hitting each venue's API and reconciling their shapes.

Detail of ONE prediction market or event by numeric id, 0x conditionId, market-slug or event-slug (auto-detected): normalized outcomes with implied probabilities, volume, liquidity, close date, status and a link-back.
