JSON Auto-Fix Service

Choose this endpoint when you have a specific, concrete JSON repair task — especially trailing commas, single-quoted strings, or unquoted keys from JavaScript object literals or LLM outputs. It is purpose-built for JSON syntax correction and returns only valid JSON with no prose, making it ideal for automated pipelines where you need clean parseable output without additional post-processing.

• Input is so malformed it cannot be unambiguously repaired — returns an error or best-effort partial fix
• Input is not JSON at all (e.g. plain text or XML) — unpredictable output
• Ambiguous structure where multiple valid repairs exist — only one interpretation returned
• Network timeout on the Cloudflare tunnel if the host machine is offline
