compile
Compile source code and return assembly output, stdout, and stderr
list_compilers
List available compilers, optionally filtered by language
list_languages
List supported languages. Each entry has `defaultCompiler` and `compilerCount`.
list_libraries
List available libraries for a given programming language
lookup_asm_instruction
Look up documentation for an assembly instruction
generate_short_url
Create a Compiler Explorer short URL for sharing code with compiler settings
get_shortlink_info
Retrieve 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 — only the basic compile
