whoami — Which checkout402 account this connection acts as, and whether the checkouts it creates move REAL money.
get_analytics — Your earnings: revenue, fees, paid calls, unique buyers, per-offer breakdown — and any payments that SETTLED but failed to deliver, which is money taken for goods the buyer never got.
list_awaiting_fulfilment — Webhook sales that have been PAID and not yet fulfilled — the work you owe buyers.
mark_fulfilled — Close out a webhook sale: say whether the buyer actually received it.
list_mcp_tools — Ask the seller's OWN MCP server which tools it advertises, so a checkout is priced against a name that actually exists.
get_payout_history — Every change to this account's payout wallets — chain, old and new address, when, and which credential did it.
quote_checkout — Read what a checkout URL costs — price, protocol fee, total, and which networks it accepts — WITHOUT paying.
pay_test_checkout — Rehearse a purchase end to end and return the goods — no funds, no private key.
