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://mesh.agentdiet.dev/v1/json-normalizer)
Output
A repaired, valid JSON object that has been cleaned of common LLM output artifacts including trailing commas, markdown code fences, single-quote delimiters, and truncation issues, ready for downstream programmatic consumption.
Example use cases
Fix LLM output in agent pipeline
“My AI agent just returned this malformed JSON with trailing commas and it's crashing my downstream processor — please repair it and give me back clean valid JSON: {"status": "ok", "items": ["a", "b",]}”
Strip markdown fences from model response
“The model wrapped its JSON output in triple backticks and added single quotes instead of double quotes — can you normalize this so I can parse it: ```{'user': 'bob', 'age': 30}```?”
Recover truncated JSON from long generation
“My LLM hit the token limit mid-generation and the JSON got cut off partway through — can you try to repair and complete this truncated JSON so it's valid: {"results": [{"id": 1, "name": "foo"}, {"id": 2, "name": "bar"”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/json-normalizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline receives raw LLM-generated JSON that fails standard JSON.parse() due to common artifacts like trailing commas, markdown wrapping, or single quotes, and you need a deterministic (non-AI, rule-based) repair rather than another LLM call to fix it. Ideal for production pipelines requiring reliable, fast, low-cost JSON normalization without introducing additional model latency or hallucination risk.
Side effects
- JSON too severely malformed or ambiguous to deterministically repair — returns error or best-effort partial result
- raw_json parameter missing or empty — returns 400-level validation error
- Input so truncated that structure cannot be inferred — repair may produce incorrect schema
- Payment not processed (x402) — returns 402 Payment Required before repair is attempted
