Wallet Cluster Detection — USDC Funding Source & Sibling Address Finder
x402
Wallet Cluster Detection — USDC Funding Source & Sibling Address Finder is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).
Given a seed wallet address, traces its USDC funding source backwards and identifies sibling addresses funded by the same source within the last 30 days, returning cluster metadata and pattern classification.

How this service works
Detect wallet cluster: given seed address, trace USDC funding source backwards then find sibling addresses funded by same source within last 30 days. Returns funder address, first funding tx, cluster_size, siblings array (up to 50), pattern classification (burner_cluster, linked_addresses, single_sibling, no_funding_found). For sybil detection, treasury monitoring, source-of-funds analysis. Accepts payment on Base or Solana — either network works.
Output
Returns a JSON object containing: the funder address that sent USDC to the seed wallet, the first funding transaction hash, cluster_size (number of related wallets), a siblings array of up to 50 sibling wallet addresses funded by the same source within the last 30 days, and a pattern_classification enum value (burner_cluster, linked_addresses, single_sibling, or no_funding_found).
Example use cases
Airdrop farming detection across wallets
“I'm seeing suspicious activity around our airdrop. Can you investigate if these recipient wallets are actually connected? Check if they share a common USDC funder and flag any burner clusters or suspicious sibling relationships within the last 30 days.”
Treasury fund misuse investigation
“We need to audit our treasury disbursements for compliance. Take this wallet address we funded and trace back to find all sibling wallets that received USDC from the same source. Tell me the cluster size and whether it looks like legitimate distribution or coordinated fraud.”
KYC source-of-funds verification
“A new user just deposited USDC to their wallet. Can you trace where that funding actually came from and identify any other wallets funded by the same source? I need to know if this looks like legitimate institutional funding or a suspicious cluster.”
Technical details
Endpoint
GEThttps://api.x402node.dev/wallet/clusterWhen to prefer
Use this endpoint when you need to perform sybil detection, airdrop farming investigation, or source-of-funds compliance checks on Ethereum or EVM-compatible wallets that transact in USDC. It is specifically designed to trace USDC funding lineage and surface sibling wallet clusters — prefer it over general blockchain explorers when you need structured cluster classification and sibling enumeration in a single call.
Side effects
- No USDC funding found for the seed address — returns pattern_classification: no_funding_found
- Invalid or malformed wallet address input — likely 4xx error
- Seed address has no on-chain USDC history within detectable range
- More than 50 siblings truncated to first 50 in results
- RPC or upstream data provider timeout causing incomplete cluster trace
