Digits Connect API

Why Digits

Integrations without the integration tax.

Legacy accounting APIs expect you to sync charts of accounts, build mapping UIs, and handle duplicates. Digits replaces all of that with a single, intelligent API.

You send the data you already have — and the AGL handles the rest. It identifies vendors, enriches context, and records balanced, categorized entries automatically. The AGL understands financial data contextually, turning raw transactions into structured accounting entries.

Built for Builders

That is great, albeit a little long compared to the other sections. Can we make it more succinct, and then can we also update the open by design section to talk about how both the API and the MCP shouldn't come with strings attached or be open for free, etc., sort of what's already there, and in

Simple to build. Reliable to maintain.

Everything you expect from a modern API — built for financial data.

• AI-native categorization: No custom mapping logic — the AGL interprets and classifies automatically.
• Vendor enrichment: Send raw descriptions, and Digits researches, identifies, and hydrates vendor details.
• Idempotent writes: Send safely and repeatedly — no duplicates, ever.
• Consistent schemas: Predictable, typed responses across endpoints.
• Full OpenAPI spec & sandbox: Generate clients, test freely, and deploy with confidence.

What You Can Build

Smarter integrations, fewer moving parts.

The Connect API removes the overhead of traditional ledger integrations.

• Direct ledger connections — Send transactions, get categorized, balanced entries.
• AI-powered enrichment — Digits researches and fills in vendor details automatically.
• Context-aware automations — Pass department, location, or project metadata into your ledger entries.
• Programmable accounting — Add intelligent ledger functionality to your product with a modern API.

Build with our MCP Server

Connect Digits to the AI tools you already use - no app required.

Not every workflow needs a custom integration or app.

Digits provides an MCP server that connects your ledger directly to tools like ChatGPT, Claude, and other MCP-compatible environments, so you can query, analyze, and automate on top of real-time financial data.
