An API that returns balanced books

Product systems post events; the ledger validates, commits double-entry, and answers reads with read-after-write consistency.

Questions

Does Ledger Rocket have a REST API or gRPC?

Ledger Rocket exposes both REST and gRPC. Product systems post an event and get a balanced set of entries and a consistent read.

Which languages do the Ledger Rocket SDKs support?

Ledger Rocket provides SDKs in five languages (Go, TypeScript, .NET, Python and Rust) plus a CLI. The current API is documented at ledgerrocket.mintlify.app.

Does Ledger Rocket have an MCP server for AI agents?

The toolkit includes an MCP server for agents, with role-based permissions. Each invoked service or tool keeps its own authorisation boundary, and AI is not a privileged bypass or a replacement for deterministic controls.

Can I query Ledger Rocket data in my own warehouse, such as BigQuery?

Ledger tables replicate to BigQuery, Athena or Trino, and you query with the tools you already use.
