Puzzle

Puzzle is real-time, AI-native accounting software for startups and accounting firms. It builds a continuously reconciled general ledger on top of connected Stripe, bank, card, and payroll data and surfaces financial statements plus startup metrics like burn, runway, and margin. The Puzzle API exposes that same real-time financial data hub and general ledger over a RESTful, OAuth 2.0-secured JSON interface. As of this catalog entry the API is in an active-development, partner-gated rollout, available to platform partners building embedded accounting and to large accounting or advisory firms; individual companies join a waitlist.

Puzzle publishes 8 APIs on the APIs.io network, including Accounts API, Categories API, Companies API, and 5 more. Tagged areas include Accounting, Fintech, General Ledger, Financial Reporting, and Bookkeeping.

Puzzle’s developer surface includes authentication, documentation, signup flow, pricing, engineering blog, and 8 more developer resources.
