Polygon Transaction Complexity Analyzer
x402
Polygon Transaction Complexity Analyzer is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).
Analyzes the structural complexity of a Polygon PoS transaction by scoring its call depth, inner transactions, instructions, keys, and logs into a complexity band and score.

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 containing a complexity band (e.g. 'low', 'medium', 'high'), a numeric complexity score, counts of calls, inner transactions, instructions, keys, and logs, an interpretation label, the analyzed network identifier, network context (accepted chain IDs, bridge model, completion policy, protocol family), warnings about complexity scope, and the service ID. Also includes a full receipt with payment metadata and a SHA-256 result hash.
Example use cases
Pre-execution complexity gate for DeFi agent
“Before I submit this Polygon transaction to a DeFi protocol, analyze its structural complexity and tell me whether it's in the low, medium, or high band — include the call count and instruction count so I can decide if it's safe to proceed.”
Smart contract audit complexity triage
“I'm reviewing a batch of smart contract interactions on Polygon Mainnet — can you score the complexity of this transaction JSON and tell me the number of inner transactions, logs, and the overall complexity band so I can prioritize which ones need deeper auditing?”
Agent pipeline complexity monitoring
“My agent just constructed a multi-step Polygon transaction. Run a complexity analysis on it and give me the score, band, and interpretation label so I know whether to flag it for human review before broadcasting.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/polygon_transaction_complexity/invokeWhen to prefer
Choose this endpoint when you need a fast, lightweight structural complexity score for a Polygon PoS transaction before execution or during audit triage, and you do not need full risk scoring, safety assessment, or finality guarantees. It is specifically calibrated for Polygon Mainnet (chain 137) and Amoy testnet (chain 80002), so prefer it over generic EVM analyzers when working within the Polygon ecosystem. It is not a substitute for security auditing or transaction simulation.
Side effects
- Invalid or malformed JSON in request_json field — service returns an error or unexpected result
- Unsupported chain ID (only Polygon Mainnet 137 and Amoy testnet 80002 are accepted)
- request_json too short (minimum 2 chars) or too long (max 65536 chars) — schema validation failure
- Missing or empty request body — returns HTTP 4xx
- Payment not supplied or insufficient USDC — x402 payment required response
- Incomplete transaction data leading to zero counts and a minimal complexity score that may not reflect true on-chain complexity
