Puzzle
Puzzle is an AI-powered accounting platform for startups, SMBs, and accounting firms, built around a real-time, append-only general ledger. Its agent-native architecture pairs deterministic Puzzle agents that draft categorization, reconciliation, and month-end close for human review with native integrations to banking, card, revenue, and payroll systems (Stripe, Brex, Mercury, Ramp, Gusto, Rippling, and more). The Puzzle Accounting API gives developers programmatic, OAuth 2.0 + PKCE-secured access to the same ledger: transactions, chart of accounts, journal entries, bills, invoices, vendors, customers, payroll, financial statements (income statement, balance sheet, cash activity), and metrics such as burn, runway, and revenue. A companion read-only MCP server connects AI tools like Claude, Cursor, and Windsurf to the ledger for natural-language financial analysis.
Puzzle publishes 22 APIs on the APIs.io network, including Accounts API, Attachments API, Bills API, and 19 more. Tagged areas include Company, Accounting, Financial, Bookkeeping, and Fintech.
Puzzle’s developer surface includes documentation, API reference, getting-started guide, pricing, engineering blog, support, signup flow, and 31 more developer resources.
