Arc Developer Docs

The Arc developer platform provides read-only access to your company's financial data through a REST API (/v1) and the arc command-line tool. People use browser login for the CLI; API keys remain available for the REST API, CI, and unattended servers.

Reference​

  • API — the /v1 REST surface: auth, resources, and conventions.
  • CLI — the arc command-line tool built on that API: install, authenticate, and the available commands.
  • MCP — a one-click connector for no-shell assistants (coming soon).
