Billy Accounting Setup (BYOK) lets an AI assistant read your own Billy Accounting Setup data through the Billy Accounting Setup API with a key you supply (Billy access token (Settings, Access tokens)). Read-only: 10 tools (list_account_groups, list_account_natures, list_tax_rates, list_tax_rate_deduction_components, list_sales_tax_rulesets, list_sales_tax_rules, list_sales_tax_returns, list_currencies, list_daybooks, list_countries). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.billysbilling.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Billy Accounting Setup. Billy Accounting Setup and its logos are trademarks of their owners and are used only to say which service the connector works with.
Sources: Live from the Billy Accounting Setup API (api.billysbilling.com) with a BYOK key; documentation: https://www.billy.dk/api/. Endpoints checked against that documentation on 2026-10-16.
