Listed in PayAI
Live prediction-market odds (Polymarket) as clean implied probabilities, so your agent can price events: q=bitcoin|ethereum|solana|fed|election|any keyword (default crypto), limit=1-20 events (default 8), markets=1-20 per event (default 6). Returns events sorted by 24h volume, each with markets [{question, outcome_label, yes_prob, no_prob, best_bid, best_ask, change_1d, volume_24h, liquidity, end_date, url}], contested markets (5-95%) first; plus top_contested (the most-traded genuinely uncertain market). When to call: hedge or size a trade on BTC/ETH price targets, read crowd odds on Fed/macro/election events, feed an event-driven strategy. 2.5x cheaper than $0.0075 prediction-market endpoints; no match returns 404 and is never charged; 60s cache.

# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to kr-x402-mvp.kgy5612.workers.dev's tracked endpoints each day, estimated from the 30-day totals the x402 catalogues report. Each bar is the change in that 30-day total since the day before, plus the calls that left the 30-day window (taken as an average day). It is an estimate: Hagglyai does not measure or pay for these calls.
