Cheap Utilities JSON Repair

Choose this endpoint when you have a known malformed or non-standard JSON string that needs to be repaired and parsed in one step — especially for LLM-generated JSON, scraped config files, Python serialized dicts, or hand-written JSON with linting errors. It handles a broad set of common JSON syntax violations in a single cheap call. Prefer it over writing custom fix logic or calling a general-purpose LLM when the input is under 4000 characters and you need deterministic repair with an audit trail of what was changed.

• Input text exceeds 4000 characters — request will be rejected or truncated
• JSON is too structurally corrupted to recover — parsed field returns null with a verdict indicating failure
• Ambiguous malformed input where multiple valid repairs are possible — one interpretation chosen without guarantee
• Non-JSON input (e.g. XML, CSV) — will fail to parse and return null result
