SignalHarness CrossChain Complexity Compare
x402
SignalHarness CrossChain Complexity Compare is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.025/call, status unknown (last checked 2026-09-13).
Analyzes and compares the structural complexity of blockchain transactions across multiple chains (Base, Solana, Polygon) and returns scored complexity bands with interpretation.

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 object containing per-transaction complexity scores, complexity bands (low/medium/high), chain labels, instruction/call/log counts, interpretation labels (e.g. structural_complexity_only), warnings (e.g. 'Complexity is not a security rating'), and the set of networks analyzed. Also includes a receipt with payment metadata and a SHA-256 result hash.
Example use cases
DeFi route complexity comparison
“I have two transactions — one on Base and one on Polygon — for the same DeFi swap. Can you compare their structural complexity scores and tell me which one has fewer inner calls and logs?”
Smart contract audit pre-screening
“Before I audit this contract interaction, can you score the crosschain complexity of this transaction JSON across Base and Solana and flag anything in the high complexity band?”
Gas optimization research
“I'm trying to figure out which chain produces the least structurally complex transactions for my bridge protocol. Can you run this transaction data through a crosschain complexity comparison across Base, Solana, and Polygon and show me the scores?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/crosschain_complexity_compare/invokeWhen to prefer
Choose this endpoint when you need a quantitative, multi-chain structural complexity score for blockchain transactions rather than a security audit or gas estimate. It is specifically suited for comparing transaction complexity across Base, Solana, and Polygon simultaneously, and is useful for routing decisions, pre-audit screening, or research into chain-specific transaction overhead. It does not assess security vulnerabilities — use a dedicated security scanner for that.
Side effects
- Invalid or malformed request_json returns an error
- Unsupported chain identifiers in transaction data may produce incomplete analysis
- Missing transaction fields may result in zero-score outputs with no band classification
- Oversized input exceeding 65536 characters will be rejected
- Network unavailability may cause execution failure with a non-succeeded status
