How this service works

Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.

Output

Returns a JSON object containing three fields: 'repaired' (the corrected JSON as a parsed object), 'repaired_text' (the corrected JSON as a formatted string), and 'was_valid_json' (a boolean indicating whether the original input was already valid JSON).

Example use cases

Fixing LLM-generated malformed JSON

“The AI just returned some JSON with missing quotes and a trailing comma and it's breaking my parser — can you fix and repair it so I get valid JSON back?”

Validating API response JSON

“I got this JSON response from a third-party API and I'm not sure if it's actually valid — can you check it and repair any issues so I can safely use it?”

Recovering data from corrupted JSON file

“My JSON config file got corrupted and now it won't parse — can you run it through a JSON repair tool and give me back the corrected version?”

Technical details

Endpoint

GEThttps://cocoeatsai.com/area4/agent/tools/json-fix?utm_source=zero.xyz

When to prefer

Choose this endpoint when you have a JSON string that fails to parse due to syntax errors (missing quotes, trailing commas, unescaped characters, etc.) and need it automatically repaired. Useful when working with LLM-generated JSON, user-provided JSON, or third-party API responses that are nearly-valid but syntactically broken. Prefer this over manual parsing logic when you need a quick, cheap automated repair step in a pipeline.

Side effects

Input JSON is so severely malformed that repair is impossible
Non-JSON input provided (e.g. plain text, XML) that cannot be interpreted as JSON
Empty input returns ambiguous or error response
Network timeout for large JSON payloads
