🟢get_service_info
Free overview of the Base Payment Assurance service. Use this to learn the supported chain/token, dual-RPC quorum, safe-finality requirement, exact-transfer policy, fail-closed behavior, and per-call credit cost. This tool does not inspect a transaction and does not require a bearer token.

}🟢get_payment_info
Free instructions for buying this service's prepaid API credits with direct native Base USDC. Returns the exact receiver, package amount, credit quantity and self-service purchase path. This funding payment is separate from any transaction that you later ask the assurance tools to inspect.

}🔴verify_usdc_payment(txHash, expectedPayer, expectedReceiver, expectedAmountAtomic)
Assure that a specific Base transaction contains an exact native Circle USDC Transfer from the expected payer to the expected receiver for the exact atomic amount. Verification requires two-RPC receipt agreement and safe finality. Use a decimal atomic amount string (USDC has 6 decimals). RPC infrastructure failures refund the credit. Costs 1 credit.
