SignalHarness Cross-Chain Transfer Correlator
x402
SignalHarness Cross-Chain Transfer Correlator 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).
Analyzes caller-supplied data to correlate cross-chain transfer events across Solana, Base, and Polygon networks, identifying candidate transaction pairs and assessing bridge completion claims.

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 analysis containing candidate transaction pairs, a boolean indicating whether bridge completion is claimed, the analyzed network scope (solana_base_polygon), evidence scope label (caller_supplied_data), and any warnings — notably that correlation does not prove bridge finality.
Example use cases
Bridge transfer investigation after delay
“My Solana-to-Base bridge transfer has been pending for hours — here's the transaction data I collected. Can you correlate it across chains and tell me if there are any candidate matching pairs and whether completion is claimed?”
DeFi audit of cross-chain activity
“I'm auditing a set of cross-chain events across Solana, Base, and Polygon. Here's the raw transfer data — can you analyze it and identify any correlated transaction pairs?”
Agent verifying multi-chain settlement
“Before I mark this trade as settled, check this cross-chain transfer data and tell me if Solana and Base transactions correlate as a completed pair or if completion is still unconfirmed.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/crosschain_transfer_correlate/invokeWhen to prefer
Choose this endpoint when you need to programmatically correlate cross-chain transfer events across Solana, Base, and Polygon from caller-supplied data — particularly when investigating bridge transactions or auditing multi-chain settlement. It is not a blockchain indexer or live chain scanner; it works only on data you provide and explicitly notes that correlation does not imply finality.
Side effects
- Malformed or empty request_json causes parse failure
- No candidate pairs found if supplied data lacks matching signals
- Service may return warnings that correlation is inconclusive
- Bridge completion claim may be false even if pairs are matched
- Input data truncated if it exceeds 65536 character limit
