How this service works
Polymarket smart money for one market: the biggest holders on each side, each scored for skill (edge, win rate, ROI), plus which way skilled money leans and whether it agrees with the market's odds. Accepts a market link, slug or condition ID. Data, not investment advice.
Output
Returns the largest position holders on both the YES and NO sides of the specified Polymarket market, each annotated with a skill score (0-100), edge over the odds paid, win rate, and ROI. Also includes a directional signal showing which way skilled money collectively leans and whether that direction agrees or disagrees with the market's implied probability.
Example use cases
Election market smart money check
“Pull up the smart money analysis for the Polymarket market on the 2024 US election winner — give me the top skilled holders on each side, their ROI and edge scores, and whether the sharp money agrees with the current market probability.”
Sports event contrarian signal hunt
“For this Polymarket market on the Super Bowl winner, show me which way the skilled whales are positioned and whether they're betting against the current odds — I want to know if there's a contrarian smart money signal.”
Research an unfamiliar market before trading
“I'm about to trade on this Polymarket market about Federal Reserve rate cuts — can you check who the biggest skilled traders are on each side and tell me if smart money is aligned with the market price or diverging from it?”

Endpoint
GEThttps://www.x402pulse.dev/v1/smart-money?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a per-market deep-dive into which specific skilled traders are holding positions and how their credentials stack up, rather than a broad scan of disagreements across many markets or a feed of recent large trades. It is the right choice when a user has a specific market in mind and wants to understand the skill-weighted sentiment and alignment with current odds for that exact market.
Side effects
- Invalid or unrecognized market URL/slug/condition ID returns an error
- Market with insufficient trading history may yield incomplete skill scores
- Very new or illiquid markets may have no scoreable traders
- Payment failure (insufficient USDC) results in 402 response
- Market may have closed or resolved, returning stale or empty data
