Return the live Base USDC destination, payout platforms, fiat currencies, payee hints, amount bounds, and pricing model. Call this before naming a rail or currency.

Estimate fiat received for Base USDC at the live Chainlink oracle rate. This is not a locked quote; the binding rate resolves when a buyer fills.

Prepare unsigned Base USDC approval and createDeposit transactions. The MCP server never accepts a private key or submits a transaction. Show the plan and obtain explicit approval before host-side signing.

Read a confirmed Base createDeposit receipt and resolve the resumable Peer deposit id. Call only after the host confirms the createDeposit transaction returned by peer_cash_prepare.

Prepare the unsigned verified-buyer access-policy transaction required for Venmo, Cash App, or PayPal orders. Use only after finalization when peer_cash_prepare returned accessPolicyRequired=true.

Return one order state, amounts, fills, and next actions from its deposit id. Brief ORDER_NOT_FOUND responses after finalization may be indexer lag; retry this read, never the deposit transaction.

List orders owned by a maker wallet, optionally limited to orders that still need attention.

Prepare unsigned transactions to withdraw unmatched funds. Omit amount to close the order; pass a Base USDC base-unit amount for a partial withdrawal.

Prepare unsigned approval and addFunds transactions to add Base USDC to a live order.
