  "description": "Returns whale, CEX, bridge, and stablecoin flow alerts for a chosen chain and lookback window, each with direction, venue, and USD value — use it to catch large capital movements before they move price. Typical agent tasks: check for a large exchange inflow on Base, monitor bridge flows into or out of a chain, track stablecoin issuer mint or burn events, or add on-chain flow context to a crypto market-intelligence pipeline. Configurable 1-168 hour lookback, USDC on Base via x402.",
