Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (8)
🟢list_assets
Every asset the swap form knows, with slug, ticker, network, confirmations, extra-id name and whether it is available right now.
Input Schema
{
"type": "object",
"properties": {}
}🟢list_routes
Every route with its own page (from/to slugs) and whether both sides are available right now.
Input Schema
{
"type": "object",
"properties": {}
}🟢get_limits(from, to)
Minimum and maximum amount for a route, in the asset you send.
Input Schema
{
"type": "object",
"properties": {
"from": {
"type": "string",
"description": "asset slug you send, e.g. usdt-trc20"
},
"to": {
"type": "string",
"description": "asset slug you receive, e.g. btc"
}
},
"required": [
"from",
"to"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_quote(from, to, amount, mode, via)
Floating estimate for a route and amount: amountTo, networkFee (taken out of the payout), receiveAmount, rate. The final amount is set when the deposit confirms.

{
"type": "object",
"properties": {
"from": {
"type": "string"

}
},
"required": [
"from",
"to",
"amount"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢validate_address(asset, address)
Whether an address has the right format for an asset. Does not check who owns it or whether an exchange needs a memo.
Input Schema
{
"type": "object",
"properties": {
"asset": {
"type": "string",
"description": "asset slug"
},
"address": {
"type": "string"
}
},
"required": [
"asset",
"address"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_swap_status(id)
Status of one swap by id: stage (1 waiting … 5 done), deposit and payout addresses, amounts (receiveAmount is the estimate after the network fee; amountReceived the deposit as credited once seen — when it differs from amountFrom the estimate no longer applies; amountTo the actual payout once known), both transaction hashes.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "swap id from the status page URL"
}
},
"required": [
"id"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟡create_swap(from, to, amount, fromAddress, toAddress, ...)
Creates the swap and returns the payment instruction: the one-time deposit address, the memo if the chain needs one, the exact amount in decimal and in base units with the decimals and token contract as listed by the liquidity partner, a wallet URI where a standard exists (BIP-21, ERC-681, Solana Pay, Monero, TON), and the status URL. Use it only when you control the wallet at fromAddress and will send the deposit yourself; for a person use swap_page_link. The deposit must come from fromAddress; there is no refund address — a swap that cannot be completed is handled by support from the swap id. Floating rate: the final amount is set when the deposit confirms.

"$schema": "http://json-schema.org/draft-07/schema#"
}🟢swap_page_link(from, to, amount, mode)
The page where the person completes the swap, with the amount prefilled. A swap for a person is completed by that person on the page: open the link, check the amount, both addresses and the memo on screen, then send the deposit from your own wallet. An agent that controls the sending wallet itself uses create_swap and pays the instruction it gets back.
