compileread-onlyCompile source code and return assembly output, stdout, and stderr
list_compilersread-onlyList available compilers, optionally filtered by language
list_languagesread-onlyList supported languages. Each entry has `defaultCompiler` and `compilerCount`.
list_librariesread-onlyList available libraries for a given programming language
lookup_asm_instructionread-onlyLook up documentation for an assembly instruction
generate_short_urlCreate a Compiler Explorer short URL for sharing code with compiler settings
get_shortlink_inforead-onlyRetrieve source and compiler config from a CE short URL. Compiler entries are returned in the `compile` tool's shape ({compiler, options, libraries:[{id, version}]}). Multi-pane shortlinks (executors, conformance views, CMake trees, per-compiler filters/tools) are flattened â only the basic compile inputs survive.
