SignalHarness Crosschain Asset Flow Reconstructor
x402
SignalHarness Crosschain Asset Flow Reconstructor is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).
Reconstructs and analyzes cross-chain asset transfer flows from caller-supplied transaction data, producing a ledger of per-account in/out/net flows across chains.

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 structured JSON ledger with per-account, per-asset, per-chain rows showing inflow, outflow, and net amounts, plus a total transfer count, the analyzed network scope, any warnings (e.g. missing bridge links), and the evidence scope indicating that data was caller-supplied.
Example use cases
Bridge audit for DeFi protocol
“I have raw transaction data from a bridge between Solana and Base involving a specific token. Can you reconstruct the full asset flow ledger showing what went in and out of each account, and tell me the net transfers?”
Wallet reconciliation across chains
“I need to reconcile asset movements for this wallet across Solana, Base, and Polygon — here's the transaction JSON. Show me all inflows, outflows, and net positions per account and asset.”
Cross-chain transfer count and flow summary
“Given this set of cross-chain transaction records across Solana and Polygon, reconstruct the ledger of asset flows and tell me the total number of transfers and each account's net position.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/crosschain_asset_flow_reconstruct/invokeWhen to prefer
Choose this endpoint when you need to reconstruct a structured ledger of asset flows from caller-supplied transaction data spanning multiple chains (e.g. Solana, Base, Polygon). It is purpose-built for cross-chain flow analysis rather than single-chain explorers or general blockchain data queries. Prefer it when you need per-account in/out/net breakdowns across chains and assets in a single call.
Side effects
- Missing or malformed request_json causes parse errors
- Asset equivalence or bridge links not supplied results in a warning and separate ledger entries rather than unified flows
- Unsupported chain identifiers may limit analysis scope
- Exceeding 65536 character limit on request_json causes rejection
- Ambiguous or conflicting transaction records may produce inaccurate net positions
