- `list\_assets`: Find the assets ChangeNOW can exchange and turn what the user said into a canonical asset id. Search by ticker, name or network, filter by network, by fiat or crypto, and by whether a fixed rate is possible. Always call this before quoting: the same ticker exists on several networks and only the can
- `get\_asset`: Everything needed to build a swap for one asset: the canonical id, the legacy ticker used in website links, decimals, whether a memo is required and what the receiving side calls it, the address format, the token contract and the warnings to relay to the user. Minimum and maximum amounts are not her
- `quote\_swap`: Ask what a swap would give, in either direction: pass amount\_from to learn what the user receives, or amount\_to to learn what the user must send. Returns the rate, the pair minimum and maximum, who would execute the order, and the warnings to relay. With rate\_type "fixed" it also returns the rate\_id
- `validate\_address`: Check a recipient address, and its memo when the asset needs one, against the format the network requires, before any order exists. Call this on every address the user gives. A valid-looking address on the wrong network is the one mistake in a swap that destroys the funds with no way back, so when t
- `swap\_link`: Build a changenow.io link with the pair, the amount, the recipient address and the memo already filled in, so the user checks the numbers on the real page and presses Confirm themselves. Opening the link creates nothing. This is the recommended way to finish a swap: the user sees the rate and the ad
- `create\_swap`: Create a real swap order and return the deposit address the user has to send funds to. This call moves no money by itself, but the order is real: it exists in support, it can expire, and a fixed rate is locked against it. Quote the swap first, validate the recipient address, and confirm the amount a
- `check\_swap\_status`: Follow an existing order by id: where it stands, what the deposit and payout amounts turned out to be, the transaction hashes, and a plain-language explanation of what the current stage means and what happens next. Use it after create\_swap, and again whenever the user asks where their swap is.
