I manually compare a small set of supplied call/payment records from one x402 integration with on-chain USDC transfers on Base Sepolia.

This service may help when a test payment's settlement outcome is unclear, a payment appears to be missing from local records, or you need an independent reconciliation of a small test run before handoff.

Before accepting the project, I check whether your question and available records fit the scope. In your first message, describe the question and the types of records you have. Do not send credentials, private keys, seed phrases, or signing material.

You receive one short reconciliation report covering up to 10 supplied records from one integration. The report identifies matches between supplied records and on-chain transfers, mismatches in the available evidence, and unresolved items, including what cannot be established from the supplied records. Evidence and limitations are stated alongside the findings. An unresolved result is a valid outcome. The service does not guarantee that every record can be conclusively reconciled.

Included: one integration on Base Sepolia, up to 10 supplied call/payment records, manual review using an agreed supported input format, and comparison with on-chain USDC transfers. The report is delivered within 7 calendar days after scope acceptance and receipt of the agreed records.

Not included: mainnet or other networks, security auditing, proof of API response delivery, integration fixes or code changes, and new parsers or custom data ingestion. If the available data requires a new parser or falls outside this scope, the project will not start under this offer. Any revised scope must be agreed separately.
