Code Execution API
Compile and run code in 35+ programming languages from a single API call — no key, no container to manage. Send source code plus an optional stdin, compiler options and runtime arguments, pick a language (python, c++, java, go, rust, c#, javascript, typescript, ruby, php, kotlin, swift, haskell, and more) or an explicit compiler version, and get back the exit code, stdout, stderr and compiler messages. List every supported language with its default compiler, browse the full compiler catalogue (175+ compilers across versions) and filter it by language. Set save=true to also get a shareable permlink. Execution runs in a sandboxed upstream and is always live (never cached). 4 endpoints, backed by the public Wandbox service. Built for online IDEs, coding-education platforms, automated grading, interview tools and "run this snippet" features. No upstream key, no cache.
