• create_split

  Create 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.

  Parameters:

  • title (required) — string — What the split is for, e.g. "Ski trip".
  • participants (required) — array — Names of everyone splitting, at least two.
  • currency — string — Currency code. Defaults to SEK.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• get_split read-only

  Read a split: participants, expenses, per-person balances and the shortest set of payments that settles everyone up.

  Parameters:

  • split (required) — string — The split key, or the whole https://split.xuper.fun/k/<key> link.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• add_expense

  Record 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.

  Parameters:

  • split (required) — string — The split key, or the whole https://split.xuper.fun/k/<key> link.
  • amount (required) — number — Amount in the split's currency, as a decimal (e.g. 249.50).
  • paid_by (required) — string — Who paid — a participant's name (or id) in this split. A card receipt rarely names the payer, so ask unless you know: guess wrong and every balance points the wrong way. If the user counts themselves among the participants, assume it was them and say that you assumed it — what you must not do is pick a payer silently.
  • date — string — Date as YYYY-MM-DD. Defaults to today.
  • shares — array — Uneven split. Either an exact `amount` per person (must add up to the total) or a relative `weight` per person (e.g. weight 2 for a couple). Don't combine with split_between.
  • description — string — What it was, e.g. "Groceries".
  • split_between — array — Names of the people sharing this cost, split equally. Defaults to everyone.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• record_payment

  Record 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.

  Parameters:

  • split (required) — string — The split key, or the whole https://split.xuper.fun/k/<key> link.
  • from (required) — string — Who sent the money — a participant's name (or id) in this split.
  • to (required) — string — Who received it — a participant's name (or id) in this split.
  • amount (required) — number — Amount in the split's currency, as a decimal (e.g. 249.50).
  • date — string — Date as YYYY-MM-DD. Defaults to today.
  • description — string — How it was paid, e.g. "Swish, 3 March". Shown in the history.
