Planned — not yet live

API reference

A REST API is planned so you can validate, format, repair, and convert JSON directly from your own applications and CI pipelines. The endpoints below describe the intended contract; none are live yet — every tool on the site today runs entirely client-side.

{ "json": "string" }

Response

{ "valid": boolean, "error"?: { "message": string, "line": number, "column": number } }

POST/v1/format

Pretty-print or minify a JSON document.

Request body

{ "json": "string", "indent": "2" | "4" | "tab" | "minified" }

Response

POST/v1/repair

Attempt to automatically fix common JSON syntax errors.
