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 including transaction hash, status (success/fail), gas used, effective gas price, execution fee, L1 fee, log count, contract address (if any), network context (accepted chain IDs, bridge model, protocol family), and a list of warnings about receipt authenticity or finality. Also includes an evidence_scope field and the analyzed network identifier.
Example use cases
Verify successful Polygon payment
“I have a Polygon transaction receipt from a payment I just sent — can you parse it and confirm the transaction succeeded, and tell me the gas fee that was actually charged?”
Debug failed Polygon transaction
“This Polygon transaction receipt shows status 0x0 and I'm not sure why it failed. Can you analyze it and extract the gas used, log count, and any warnings from the receipt JSON?”
Audit Polygon DeFi execution fees
“I need to audit the execution fees on a batch of Polygon PoS transactions. Here's one receipt JSON — can you extract the effective gas price, total fee paid, and network context so I can compare costs across transactions?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/polygon_receipt_analyze/invokeWhen to prefer
Choose this endpoint when you have a raw Polygon PoS transaction receipt JSON and need to extract structured fee, status, and network metadata from it programmatically. Ideal for agents that need to verify payment completion, audit gas costs, or parse Polygon receipts as part of a larger workflow. Not suitable for Ethereum mainnet, Arbitrum, or other EVM chains — it is specifically calibrated for Polygon PoS (chain IDs 137 and 80002).
Side effects
- Malformed or invalid JSON in request_json field causes parsing failure
- Missing required receipt fields may produce incomplete analysis or warnings
- Finality and authenticity of the receipt are not verified — warnings always included
- Non-Polygon receipts (wrong chain ID) may produce incorrect or partial results
- Oversized input exceeding 65536 character limit will be rejected
