List all groups and get group details.

Need to know which group owes what? You can run `get_groups` first to see every shared circle. Then, call `get_group` with a specific ID to pull the full balance sheet for that set of people. This is perfect for checking if the rent split was actually settled or if someone forgot to add an expense after the fact.

Create and track new expenses.

When someone pays cash, you can't wait until the end of the month. Use `create_expense` right away. Just pass it a JSON object with all the details—who paid, what it was for, and how much everyone owes. It handles complex splits automatically, making sure that the ledger is correct before your agent moves on to anything else.

Get specific user or friend data.

If you're confused about who's in a group, start by listing all contacts with `get_friends` or checking out a single person using `get_user`. You'll get their full profile details. This helps your agent verify identities and confirm that the right people are included when calculating shares for an expense.
