Build on Bitcoin accounting

We solved the edge cases so you don't have to. Self-host, integrate, ship.

Bitcoin accounting is hard to build

Cost basis calculations across wallet types are deceptively complex
Handling on-chain, Lightning, and multisig requires specialized logic
Maintaining accuracy at scale becomes brittle as your product grows
Generic APIs don't speak Bitcoin
AI coding tools can't work with most accounting systems. APIs weren't designed for agents, CLIs weren't designed for scripts.
Building from scratch means months lost to edge cases you haven't discovered yet

Deploy the server, hit the API, ship your product. The edge cases are already handled.

Deploy the Server in your stack with full REST API access
Automate workflows and batch operations with the CLI
LLM-friendly API and scriptable CLI. Any agent that can make HTTP requests or run shell commands can work with Clams.
Ship accounting features with Claude Code, Codex, or Cursor. The edge cases are handled, let your agent write the glue.
Native support for on-chain, Lightning, and multisig wallets
Accurate cost basis, transfer matching, and audit-ready exports
Provide accounting features to your users without building from scratch
