All Linux Syscalls, 27 Architectures, in One searchable API

What is I've updated my Linux System Call website and API?

syscall.sh now hosts the complete Linux syscall tables for 27 architectures, showing numbers, arguments and registers from kernel 3.3 to 7.3. The data is available as HTML tables and as JSON files via a simple REST API.

Who it is for

Kernel developers, reverse engineers and low-level programmers can look up syscall signatures without digging through source trees.

How to try it

curl https://api.syscall.sh/v2/syscalls/x64/read
