Swiss-made · Built in Rust

The reliable Rust layer for production AI agents

We build api0: your existing software, usable from Teams, WhatsApp, Telegram and Claude. Every action runs as the person asking.

Our product

api0: your software, in the chat your team already uses

Import your API once. Your team and your customers use it from Teams, WhatsApp, Telegram or Claude, in their own language. api0 decides who is calling, which credential your backend receives and what the call costs.

“Book me a flight to Lisbon” → a real API call

  1. 1

    Import your endpoints

    Paste an OpenAPI spec or describe endpoints in plain English. Each one becomes an MCP tool.

  2. 2

    Connect the client

    Send your team one link. Each person adds it to Claude or Teams, or links WhatsApp or Telegram, once.

  3. 3

    Govern execution

    Every call is checked, sent with your backend’s credential, metered in credits and logged.

Rust and Swiss-made, by design

Agents that touch real systems need software that doesn’t break. Everything we ship is written in Rust and built in Switzerland, from the api0 gateway to our desktop tools.

  • The api0 gateway and all its backends are written in Rust
  • Desktop tools ship as single native binaries: no Electron, no telemetry unless you opt in
  • Code-signed and notarized builds, verified on install
  • Built and supported from Switzerland
