Impacto significativo en la atención (2.01% del contexto de 128k)
Este es el número aproximado de tokens que se consumen cada vez que las herramientas del servidor se cargan en el contexto de un modelo. Los recuentos más altos reducen la atención disponible para otras tareas.

🟢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.

}🔴decode_usdc_transfers(txHash)
Decode all native Circle USDC Transfer logs from a Base transaction only after dual-RPC receipt agreement and safe finality. A not-found, failed, or not-yet-safe transaction is returned as an assurance result; RPC infrastructure failures refund the credit. Costs 1 credit.

}🔴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.
