About YJTOON
The datasets sit in 27 categories, from programming languages and operating systems to physics, history and law. A dataset URL returns the same content as JSON, YAML or TOON, a compact format that the site describes as using fewer tokens than JSON. A search covers all 185 datasets and opens with the slash key.
The site reports that TOON uses 32% fewer tokens than the JSON it serves, and 60% fewer on the best dataset. These are the site's own figures, and they were not checked independently for this entry. Each dataset page also offers a copy-ready curl command, so the data can be fetched from a terminal or a script.
