Polygon ERC20 Transfer Analyzer
x402
Polygon ERC20 Transfer Analyzer is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).
Analyzes caller-supplied Polygon PoS ERC20 transfer data and returns structured breakdowns of token movements, amounts, addresses, and network context.

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 analysis JSON containing network context (accepted chain IDs, bridge model, completion policy, protocol family), transfer details (from/to addresses, atomic amount, token, transaction hash, log index, index), evidence scope, analyzed network, plus a status field, warnings array, and a signed receipt with payment metadata and result hash.
Example use cases
Audit DeFi token transfer event
“I have some raw ERC20 transfer log data from a Polygon mainnet transaction and I want to know the exact from/to addresses, token, and atomic amount involved — can you run it through the Polygon ERC20 transfer analyzer and give me the full breakdown?”
Validate cross-bridge token movement
“We received a token transfer on Polygon PoS and need to confirm the transfer details match what was expected from the Ethereum bridge — can you analyze this transfer JSON and check the amounts and addresses for chain ID 137?”
Debug failing ERC20 transfer in agent pipeline
“My agent sent an ERC20 transfer on Polygon but I'm not sure if it went through correctly — here's the transfer data I captured, can you decode and analyze it so I can see the structured output including any warnings?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/polygon_erc20_transfer_analyze/invokeWhen to prefer
Choose this endpoint when you have caller-supplied Polygon PoS ERC20 transfer data that needs to be parsed, structured, and annotated with network context — especially when you need atomic-level transfer breakdowns, from/to address extraction, and chain-specific metadata for chain IDs 137 or 80002. Prefer this over general blockchain explorers when you already have the raw transfer data and need a programmatic, agent-consumable structured analysis rather than a UI-based lookup.
Side effects
- Malformed or non-JSON request_json causes parsing error
- Missing required transfer fields result in incomplete or warning-heavy analysis
- Unsupported chain ID (not 137 or 80002) may yield unexpected network context
- Decimals and token success state are never inferred without explicit evidence — always generates a warning
- Overly large request_json (>65536 chars) rejected at input validation
- Payment failure via x402 protocol results in no execution
