Smart money detection + auto-profiled wallet scorecards for Polymarket markets in one x402 call.
What it does
The `/api/v1/smart-money-deep` endpoint from PolyNews Intelligence API combines smart money detection with automatic wallet profiling in a single parallel call. Given a Polymarket event ID or slug, it identifies suspicious and notable wallets trading on that market, then auto-profiles the top N wallets (up to 5) with sharp scores, trader badges, ROI, and P&L metrics. This combo endpoint costs $0.10 USDC per call on Base, which is approximately 9% cheaper than calling `/smart-money` ($0.05) and `/wallet` ($0.02 × 3 wallets = $0.06) separately.
The endpoint accepts a POST request with a JSON body containing a required `marketId` field, an optional `conditionId` for multi-outcome markets, and an optional `topN` parameter (default 3, max 5) controlling how many wallets get profiled. The response includes a `smartMoney` object with signals, suspicious wallets, holder positions, insider confidence scores, and trade recommendations, plus a `walletProfiles` array with per-wallet performance data.
PolyNews is part of a broader prediction market intelligence API suite that includes Grok AI-powered analysis, cross-platform Polymarket × Kalshi arbitrage detection, real-time trade feeds, and price history. All paid endpoints use the x402 micropayment protocol — no API keys or subscriptions required. Agents pay USDC on Base automatically via the x402 facilitator. The USDC receiver address is `0x6ee49a7872844397Fb52870Cc07b308fFADC9427`.
Capabilities
Use cases
- —Detect insider or whale activity on a specific Polymarket event before placing a trade
- —Profile the top suspicious wallets in a market to assess information asymmetry
- —Build automated trading agents that factor smart money signals into bet sizing
- —Monitor notable wallet positions and sharp scores across prediction markets
- —Screen markets for unusual wallet clustering or coordinated trading patterns
Fit
Best for
- —Autonomous trading agents that need smart money + wallet data in one call
- —Prediction market researchers analyzing wallet behavior patterns
- —Algorithmic traders looking for insider signals on Polymarket events
Not for

Quality
Full OpenAPI 3.1 schema with detailed request/response definitions, live 402 challenge confirmed, clear pricing ($0.10 USDC), and comprehensive docs page. Slightly below 0.9 because the response schema for smartMoney and walletProfiles inner objects are typed as generic objects without full property definitions.
Warnings
- —Response sub-schemas for smartMoney signals and walletProfiles items are typed as generic objects — exact field shapes must be inferred from sibling endpoints (/smart-money and /wallet).
- —This endpoint provides prediction market trading signals which should not be treated as financial advice.
