Who is buying the prediction-market line: Polymarket wallet records, board, edges, entries.
Remote MCP server exposing Polymarket prediction-market data: market boards, wallet records, line gaps, smart-money entries and heat scores.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/xyz.groundtruths%2Fgroundtruth/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Who is buying the prediction-market line. Polymarket wallet records, the market board (who is in, per market), GT line vs Smart-money line gaps, and the smart-money entry feed. Counts from the Polygon chain, each with its sample size. Paid per call over x402 (USDC on Base or Solana), or free to connect over MCP.
The memecoin tools are paused; everything below is prediction-market data.
/x402/... is the always-402 door a bazaar validator probes. /v1/pm/... answers the free rows without a
payment and a 402 for the rest. Same prices, one constant in the worker.
Sign the requirement and send the payload back in PAYMENT-SIGNATURE (any x402 client does this; @x402/fetch works):
Each market comes back with its sides, price, $ and wallets, the tagged wallets holding each side (SMART MONEY / WHALE / BOT/MM), the GT line and the Smart-money line. No sportsbook odds and no Kalshi price ever ride these routes.

LINE CHECK: who is buying the prediction-market line. Polymarket games starting in the next 72 h and the US midterm race board (Nov 3): per market, the side with the most fresh-or-clustered money, its $ and wallets (k of N), price, HEAT 0-100 with its N, and the pre-start stamp hash. Counts from the Polygon chain. Information only, not financial advice.
Takes no parameters.
HEAT for one Polymarket market (condition id): the share of a side's $ from fresh or clustered wallets, ranked 0-100 against sides with real money (>= $1,000 on the side and some fresh-or-clustered $), with N. heat is null (with the reason) when the market has none. Information only, not financial advice.
cidrequiredGROUNDTRUTH market board: who is in on Polymarket games and US midterm races. Per market: sides, price, $, wallets, tagged holders, GT line and Smart-money line. Top 3 per board free; a paid key or x402 (https://api.groundtruths.xyz/x402/v1/pm/board) returns every market. Information only, not financial advice.
Takes no parameters.
Markets where GT line and the Smart-money line sit 3+ points apart on the same side, with the fills and wallets behind each. Top 3 free; the rest paid. A gap is not a call.
Takes no parameters.
Smart-money entry feed: wallet, side, $, price, time, lag, and whether GT logged it live, late, or rebuilt it afterwards. Newest 3 free; the rest paid.
nA Polygon (Polymarket) wallet's record: won X of Y with the sample size, P&L (labelled GT audited or Polymarket receipt), category split, tag. Paid only (x402 https://api.groundtruths.xyz/x402/v1/pm/wallet?addr= or a paid key). A record belongs to a wallet, not a person.
