How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object with a status field ('succeeded'), wallet_replacement_groups identifying clustered replacement transactions, warnings about data issues or edge cases, evidence_scope indicating whether analysis is based on caller-supplied data, and a detailed receipt including payment ID, execution ID, network, asset, latency, and a SHA-256 hash of the result for verification.
Example use cases
Detect wallet swap in transaction log
“I have a transaction history where I suspect the wallet address was swapped mid-way — can you analyze this request and tell me the wallet replacement groups and any warnings that come up?”
Fraud investigation for wallet substitution
“We're investigating a potential fraud case involving wallet replacement. Can you run this wallet replacement request through SignalHarness and return the grouped replacement transactions and evidence scope?”
Audit blockchain wallet changes
“For this compliance audit, I need to identify all wallet replacement events in our transaction data — please analyze this wallet replacement request and group the results.”
