Tools
| Tool | Description | Behaviour |
|---|---|---|
| create_support_ticket | For a failed or stuck swap: orderId and what happened; never seed phrases or private keys. Returns ticketId; no tool reads replies (follow up at [email protected]). | Changes data |
| create_swap | Step 2. Creates the order from get_quote's next.arguments (quoteId, plus to if the quote had none): one order per quote; moves no funds. Retry with the same arguments: the default idempotencyKey returns the same order. Fund once, only while payable is true: before signing deposit.payment, get_swap_status {orderId, payment} must return paymentCheck.matches. Next: get_swap_status. | Changes data |
| get_capabilities | Optional. Chains, limits (provider minimum, USD), quote window, idempotency, validation rules, polling and the flow. | Read-only |
| get_funding_options | Offline. How to get what the user sends: native USDC (not USDC.e) plus a little ETH for gas on Arbitrum One (u2x, default), or XMR in their own wallet (x2u). Pass from {chain, asset} (and amount) for one ordered checklist: quote, fund, re-quote (requoteOf). | Read-only |
| get_quote | Step 1. Quote XMR <-> native USDC on Arbitrum One. Read-only; quotes are estimates. Buy XMR ("get me 1 XMR"): {direction:"u2x", receiveAmount:"1"}. Sell XMR: {direction:"x2u", amount:"0.5"}. direction plus exactly one of amount (what the user sends) or receiveAmount (what they want). Pass to if known; re-quote with {requoteOf}. Next: create_swap with next.arguments; no confirmation step is required. | Read-only |
| get_swap_status | Step 3. waiting_for_funding -> deposit_detected -> swap_processing -> completed, or refunding / terminal_failure (outcome refunded, failed, expired). Long-poll with waitSec 25 and sinceState = the last state; repeat next until terminal. deposit.payment may be used only while payable is true. Call it before funding or showing a deposit again. payment: what your wallet will sign; sign only if paymentCheck.matches. | Read-only |
| list_swaps | Find orders when the orderId is lost (new chat, crash, unknown create outcome): pass the idempotencyKey create_swap used (default q_<quoteId>), or a sessionId. Read-only; addresses redacted; states can lag. Next: get_swap_status (live state, payable). | Read-only |
| plan_swap | Optional, offline. Checks a partial request (direction, amount or receiveAmount, to) and returns the next question for the user. Skip it when you have what get_quote needs. | Read-only |
