How this service works
Polymarket whale trades and smart-money signals from the Predge tracking pipeline, sold per-call over the x402 payment protocol. No API keys, no accounts.
Output
Returns a JSON object with market metadata (title, status, category, yes_price, resolution), a list of individual whale trades (side, price, size_usd, wallet address, wallet_score, wallet_win_rate_30d, block_timestamp, tx_hash), daily/bucketed volume aggregates (trades count, avg_price, volume_usd, whale_volume_usd per bucket), the requested window, and an outcome_verified object indicating whether flow and resolution signals are confirmed.
Example use cases
Whale sentiment check before trading
“Before I take a position, check the last 30 days of whale trades on Polymarket for condition 0x178a746e2b342c25b1d78d0f0d0ea77157c9b6d40b2e97ffbf827cd7f9994c39 — are high-score wallets piling in on yes or no, and what does the volume trend look like?”
Smart-money signal monitoring for agent
“Every morning, fetch the 7-day whale trade history from Predge for Polymarket condition 0xabc123…and alert me if any wallet with a score above 75 and a 30-day win rate above 60% has made a trade larger than $10,000 USD.”
Research report on a political prediction market
“I'm writing a report on the Fed rate cut market on Polymarket — grab all available whale trade history for condition 0x178a746e2b342c25b1d78d0f0d0ea77157c9b6d40b2e97ffbf827cd7f9994c39 and summarize the biggest trades, the wallets involved, their win rates, and whether the outcome has been verified.”

Endpoint
GEThttps://x402-api-production-266e.up.railway.app/v1/markets/%7BconditionId%7D/historyWhen to prefer
Choose this endpoint when you need granular historical whale trade records for a specific Polymarket market, including individual wallet intelligence (scores, win rates), bucketed volume timelines, and outcome verification signals. Prefer it over general market price feeds when smart-money flow analysis or wallet-level attribution is required. Use the all window for full market history or 7d/30d for recent activity. It is pay-per-call with no account required, making it ideal for on-demand agent queries.
Side effects
- Invalid or malformed conditionId path param returns an error or empty result
- Unknown conditionId with no tracked trades returns empty trades array
- Payment not processed via x402 protocol results in 402 Payment Required response
- Invalid window enum value (anything other than 7d, 30d, all) may return error or default to 30d
- Railway deployment downtime causes 502/503 response
- Rate limiting or stale data if tracking pipeline has a delay
