How this service works
Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.
Output
Returns a JSON object with summary, large transfer records, priority/review/avoid queues, risk breakdown per transfer, risk flags, token summaries, bucket counts, source status, and purchase/repeat-guard metadata for agent workflows.
Example use cases
Whale alert for DeFi risk desk
“Check Base chain right now for any USDC or WETH transfers above $500,000 in the last 500 blocks — I want to see the top 10 flagged by risk level so I can assess market impact.”
Autonomous agent on-chain monitoring
“Every few minutes, scan Base for large ERC20 transfers above $100k across USDC and WETH in the last 300 blocks, and alert me if anything lands in the priority risk queue.”
Pre-trade whale positioning check
“Before I put on this DeFi position, scan the last 1000 Base blocks for large transfers on USDC — show me up to 20 results so I can see if there's unusual whale activity right now.”
Technical details
Endpoint
GEThttps://x402.xx402.icu/api/base-large-transfer-radar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, risk-ranked large ERC20 transfer detection specifically on the Base L2 network, especially for USDC and WETH whale monitoring. Prefer it over generic blockchain explorers when you need pre-scored risk queues, avoid/review/priority triage, and agent-ready JSON output — particularly in autonomous risk or DeFi monitoring workflows that support x402 micropayment-per-call patterns.
Side effects
- Invalid or non-Base ERC20 token address returns empty or error response
- block window below 100 or above 3000 rejected by schema validation
- token_limit above 5 causes validation error
- payment not processed via x402 protocol results in 402 response before data is returned
- no transfers above min_usd threshold returns empty large_transfers array
- RPC or chain-read source unavailability reflected in source_status field
