How this service works
Paid crypto market-intelligence API for autonomous agents. Calibrated ranges, signal context, risk state, decision journals, and outcome audits via x402 micropayments on Base.
Output
Returns a JSON object with the queried chain name, the time window in hours, a count of alerts found, and an array of alert objects. Each alert includes the type (e.g. exchange_flow), venue name (e.g. Coinbase), direction (in/out), and USD value of the transaction.
Example use cases
Pre-trade whale activity check
“Before I make a large ETH trade, check if there are any significant whale movements or exchange inflows on Ethereum in the last 8 hours that I should know about.”
DeFi protocol risk monitoring
“Scan Base for any large exchange outflows or whale alerts in the past 24 hours — I need to know if there's unusual capital movement that could affect liquidity.”
Arbitrage opportunity scouting
“Pull the latest whale alerts on Arbitrum for the last 2 hours — I'm looking for big exchange inflows that might signal a price move I can act on.”
Technical details
Endpoint
GEThttps://kronos.forgemesh.io/api/whaleWhen to prefer
Choose this endpoint when you need real-time or near-real-time detection of large on-chain transactions and exchange flows across Ethereum, Base, or Arbitrum, especially in autonomous agent pipelines that can handle x402 micropayment flows. Prefer this over generic market data APIs when you need whale-specific signals (exchange venue, direction, USD value) rather than price feeds or order book data.
Side effects
- Payment not received or insufficient USDC — x402 payment required error returned
- Invalid chain value outside allowed enum (ethereum, base, arbitrum) — validation error
- Hours parameter outside 1–168 range — request rejected
- No whale alerts in the requested window — returns empty alerts array with alert_count 0
- Network or upstream data provider unavailability — 5xx error
