What is Predge Whale Data MCP?

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.

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.

Our take on Predge Whale Data MCP

Per-call prices and a configurable cap make individual costs visible. Delayed data, mainnet setup and no conversation-wide cap limit casual use.
