roundwatch.prepare_watch

Validate one expected future Algorand USDC payment and return the exact RoundWatch HTTP/x402 request to create a durable watch. This tool does not settle the x402 payment and does not create the watch by itself.

read-only

Argument	Type	Description
invoiceNote	string	Optional exact UTF-8 Algorand transaction note, maximum 128 UTF-8 bytes.
atomicAmount*	string	Exact watched USDC amount in atomic units. Algorand USDC uses 6 decimals.
expectedSender*	string	Checksum-valid nonzero Algorand address expected to send the future payment. The Algorand zero address is rejected for new watch creation.
idempotencyKey*	string	Stable key that identifies this watch request and prevents duplicates.
expectedReceiver*	string	Checksum-valid Algorand address expected to receive the future payment.
