Every agent-payable API.

Payment arrival alert: watches an XRP Ledger address for up to 24 hours and POSTs a signed webhook when a matching payment is final (validated, tesSUCCESS, delivered amount checked), or a watch.expired event if none arrives. Payments that land during restarts are still caught. Useful when waiting on an incoming payment without polling.

Verifies that an XRP Ledger payment settled as expected: validation, result code, destination, destination tag, currency, issuer, and the amount actually delivered, which exposes partial-payment tricks. Useful when confirming that a customer or counterparty really paid.

Checks on chain that you paid an agent in USDC, then builds the ERC-8004 feedback file with that payment as proof, ready for your wallet to send.

🆕 Commerce Payments flows are DRIVEN by an operator — it authorizes escrow, captures for merchants and takes the fees. This audits one before you rely on it: 90-day volumes, fees taken, capture-vs-reclaim record (missed capture windows = merchants left unpaid), distinct payers and merchants. verdict: healthy_operator / mixed / sloppy_operator / no_activity. No other tool reads this new Base commerce protocol.

Pre-payment public-chain and caller-context checks for an agent before it pays an x402 resource.

Verifies that a transaction hash settled a USDC payment to a given recipient, returning the parsed transfer and confirmation count.

Payment-Injection Screen by Agentropolis: send text your agent is about to act on (tool result, web page, email, file). Flags payment-looking instructions: pay/transfer requests, fake licence or refundable fees, swapped wallets, token approvals, seed-phrase asks, hidden text. Returns clean/caution/likely_payment_injection with evidence. Advisory only.
