How to choose
- API or app onlyCheck whether there is a documented API or MCP server, since many budgeting apps can only be used by a person in their own app.
- How accounts are connectedCheck which aggregator connects the bank accounts and what credentials it holds, because an agent reading budgets is reading every transaction.
- Cancellation and negotiation feesCheck what cancelling or negotiating a bill costs, as some services take a share of any saving they report.
- Write accessCheck whether the API can create transactions, edit categories or change budgets, or only read them, since read-only access limits what an agent can do.
How the benchmark tests this category. In this run, public evidence against the published checklist. When the task suites run, one test budget with a set of transactions read through each listing's API, a recurring charge identified and, where offered, a cancellation requested. We check the data returned, write access, how accounts connect and fees.
Each one in detail
