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://github-audit.agentdiet.dev/v1/json-fix)
Output
A repaired, valid JSON object derived from the input malformed string, with syntax errors corrected — trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncations resolved where possible.
Example use cases
Fix LLM JSON before pipeline processing
“My agent just returned this malformed JSON with a trailing comma and markdown fences — please repair it so I can pass it to the next step: ```json {"user": "bob", "items": [1, 2, 3,]} ```”
Recover truncated JSON mid-generation
“The model got cut off and I have this incomplete JSON: {"order_id": "abc123", "status": "pending", "items": [{"sku": "X99" — can you repair it so it's valid and parseable?”
Sanitize single-quoted JSON from scraped data
“I scraped some data and it came back using single quotes instead of double quotes: {'product': 'widget', 'price': 9.99} — can you fix it into proper valid JSON?”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/json-fix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an LLM or agent in your pipeline has produced malformed JSON that causes downstream parsing failures — especially common issues like trailing commas, markdown code fences, single quotes, or mid-generation truncations. Prefer this over manual parsing logic or regex hacks when you need deterministic, reliable repair in automated multi-agent workflows.
Side effects
- Input JSON is too severely malformed or ambiguous to deterministically repair — returns an error or best-effort output
- Input string is completely empty or not JSON-like at all
- Truncation is so extreme that the original structure cannot be inferred
- Rate limit or payment failure for x402 micropayment
