Discovery lists endpoint schemas and prices without a buyer key, so research can start before payment setup. Paid tools cover large trades, wallet history, comparisons, rankings, movers, category digests and smart-money summaries. The latest-whale route documents a 15-minute delay. Signed attestations record provider-reported market, game or wallet results and provenance; they are not order execution. Paid requests use mainnet USDC through supported Base or Solana routes. MAX\_PRICE\_USD rejects an excessive individual quote but does not cap the total spend of a conversation or batch. ### Who it is for - Developers building wallet-research agents. - Users preferring per-call data to subscriptions. - Researchers comparing past claims with settled outcomes. ## Clients and supported operations - **Free endpoint discovery** List schemas and prices without a buyer key. - **Whale activity** Read large trades and market-specific flow. - **Wallet comparisons** Inspect wallet histories, comparisons and leaderboard entries. - **Market digests** Retrieve movers, category summaries and smart-money signals. - **Signed outcomes** Read supported market, game and wallet-result attestations. - **x402 micropayments** Pay eligible calls through configured Base or Solana USDC routes. - **Per-call price cap** Reject quotes exceeding MAX\_PRICE\_USD before payment. ## Development workflows ### Research incrementally Discover tools first, request a profile, then buy bounded history or comparison only for the next question. ### Check a past claim Resolve market/game identity, retrieve its attestation and compare the claimed side and time window. ### Track aggregate cost Set an explicit call cap and count total paid requests separately during a batch. ## Pricing and total cost Typical paid calls are around US$0.005–US$0.03, with a default US$0.05 per-call cap. Discovery is free. Payments use mainnet USDC; the facilitator covers the payment transaction’s network fee. ## Installation and configuration 1. Configure the MCP package and call free endpoint discovery. 2. Set MAX\_PRICE\_USD and configure the supported USDC route for paid requests. 3. Start with a bounded market/wallet query and track aggregate spending separately. ## Useful links ### What to check - Latest-whale data is delayed by 15 minutes. - MAX\_PRICE\_USD caps one request, not a conversation or batch. - Production is mainnet-only; testnet needs a separate compatible deployment. - Attestations report provider results and provenance, without trade execution. - Some Kalshi flow routes are outside the MCP package.
