/exec
Run a shell command in a fresh isolated sandbox (Linux container with python3, node, git, and common CLI tools) and get stdout, stderr, and the exit code. $0.01 flat per command. Each call runs in its own single-use container, so installed packages and files do not persist between calls; chain steps inside one command with && when needed. Execution is capped at 60 seconds (timeout_ms, default 30000). The body is validated before charging and infrastructure failures are refunded automatically; a non-zero exit code is a successful execution and is returned, not refunded.
