YAML result

name: TempKit
items: [tools]

JSON API

/api/tools/yaml-formatter-validator

POST JSON to this endpoint using the same field names as the form. Invalid input returns a structured 400 response.

curl -X POST https://tempkit.8u.ee/api/tools/yaml-formatter-validator -H 'Content-Type: application/json' -d '{"input":"name: TempKit\nitems:\n  - tools"}'

How it works

TempKit parses YAML with a safe constructor, limits aliases, rejects tab indentation, and returns a normalized dump.
