    create_splitCreate a new xupersplit for sharing expenses in a group. No account needed. Returns a secret link — give it to the user and tell them to share it with the group, since anyone holding the link can see and edit the split.
    get_splitRead a split: participants, expenses, per-person balances and the shortest set of payments that settles everyone up.
    add_expenseRecord something one person paid for the group. Split equally by default; pass split_between for a subset, or shares for an uneven split. One expense covers one set of people — a receipt whose items aren't all shared by everyone is several expenses, so call this once per group of items that the same people share, rather than splitting the total equally. Works on simple, accountless splits. Secure splits (created by a signed-in user) are read-only here and must be opened in a browser.
    record_paymentRecord that one person paid another back, settling part or all of a debt. Use get_split first to see who should pay whom. Works on simple, accountless splits. Secure splits (created by a signed-in user) are read-only here and must be opened in a browser.
    update_entryChange an existing expense or payment. Only the fields you pass are changed. Entry ids come from get_split. Works on simple, accountless splits. Secure splits (created by a signed-in user) are read-only here and must be opened in a browser.
    delete_entryRemove an expense or payment for good. Works on simple, accountless splits. Secure splits (created by a signed-in user) are read-only here and must be opened in a browser.

    set_payment_methodsSet how a participant wants to be paid back, so the split can show a QR code or pay link. Replaces their current list (pass an empty array to clear it).
