How this service works
Repairs truncated or malformed LLM JSON outputs (trailing commas, markdown fences, single quotes) so multi-agent pipelines never crash. (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-intel.agentdiet.dev/v1/json-fix)
Output
A repaired, valid JSON object that has had common LLM-output defects corrected, including trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed — ready for direct use in downstream agents or parsers.
Example use cases
LLM output sanitization in agent pipeline
“The language model returned this JSON but it's malformed with trailing commas and single quotes — fix it so my pipeline doesn't crash: {"items": ['apple', 'banana',], 'count': 2,}”
Fixing markdown-wrapped LLM JSON
“My AI returned a JSON block wrapped in triple-backtick markdown fences and I need clean parseable JSON. Can you strip the fences and repair this: ```json
{"status": "ok", "data": {"value": 42,}}
```”
Recovering truncated JSON from a cut-off response
“The LLM response got cut off mid-way and the JSON is incomplete — it's missing closing brackets. Can you repair this truncated JSON so I can use it: {"user": {"name": "Bob", "settings": {"theme": "dark"”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/json-fix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent or LLM pipeline receives JSON that fails standard parsing due to common LLM formatting errors (trailing commas, markdown code fences, single quotes, truncation). It is preferable to ad-hoc regex fixes or manual parsing workarounds because it handles multiple failure modes deterministically in a single call, at low cost ($0.002/call), with MCP/A2A protocol compatibility.
Side effects
- JSON too severely corrupted to deterministically repair — returns error with description
- Input string is not JSON-like at all — may return unmodified or with error
- Ambiguous truncation with multiple valid completions — may choose one interpretation
- Network or payment (x402) failure — returns 402 or 5xx response
- Empty raw_json input — returns validation error
