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: (1) market metadata (title, status, category, yes_price, condition_id), (2) an array of individual whale trades each with side, price, wallet address, transaction hash, size in USD, wallet score, block timestamp, and 30-day wallet win rate, and (3) a summary with net_flow_usd, whale_trades count, yes/no volume USD, unique_wallets, and total whale_volume_usd — all covering a 7-day window with a 15-minute data delay.
Example use cases
Fed rate cut market whale check
“Show me what the big smart-money wallets are doing on the Polymarket 'Will the Fed cut rates in September?' market — condition ID 0x178a746e2b342c25b1d78d0f0d0ea77157c9b6d40b2e97ffbf827cd7f9994c39. I want to know the net flow, how many whale trades there were, and which wallets with high win rates are buying YES.”
Pre-trade whale sentiment check
“Before I take a position on Polymarket condition 0x178a746e2b342c25b1d78d0f0d0ea77157c9b6d40b2e97ffbf827cd7f9994c39, can you check what the whales have been doing on that market over the last 7 days? Show me the yes vs no volume and any wallets with wallet scores above 70.”
Automated smart-money signal alert
“Every hour, check whale activity on my tracked Polymarket market condition 0x178a746e2b342c25b1d78d0f0d0ea77157c9b6d40b2e97ffbf827cd7f9994c39 and alert me if the net USD flow flips direction or a whale wallet with a 30-day win rate above 60% makes a trade larger than $10,000.”
Technical details
Endpoint
GEThttps://x402-api-production-266e.up.railway.app/v1/whales/market/%7BconditionId%7DWhen to prefer
Use this endpoint when you need per-market whale and smart-money trade data for a specific Polymarket condition, including individual wallet-level signals with win rates and wallet scores. Prefer this over the top-movers or top-wallets endpoints when you already have a specific condition ID and want deep per-trade detail rather than a cross-market or cross-wallet ranking view.
Side effects
- Invalid or malformed conditionId returns an error or empty result
- Market not found on Polymarket returns no data
- Payment failure via x402 protocol blocks the response
- Data delay of up to 15 minutes means very recent trades may be missing
- conditionId for a resolved or delisted market may return stale or empty trade arrays
