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://sec-intel.agentdiet.dev/v1/json-validator)
Output
A repaired, valid JSON object derived from the input malformed string, with syntax issues such as trailing commas, single quotes, markdown code fences, and truncation resolved deterministically. The response is a JSON object containing the fixed output ready for downstream consumption.
Example use cases
Fix LLM response before pipeline continues
“My language model returned this JSON but it's wrapped in triple backticks and has trailing commas — fix it into clean valid JSON so my pipeline doesn't crash: ```{"user": "bob", "score": 95,}```”
Repair single-quoted JSON from agent output
“An agent in my workflow returned JSON using single quotes instead of double quotes and it's breaking my parser — can you repair this into valid JSON: {'items': ['apple', 'banana'], 'count': 2}”
Recover truncated JSON from LLM
“The model's response got cut off mid-JSON and now it's invalid — try to repair this truncated string into the most complete valid JSON you can: {"results": [{"id": 1, "title": "foo"}, {"id": 2, "title":”
Technical details
Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/json-validator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an LLM or agent in your pipeline has returned broken, truncated, or markdown-wrapped JSON that must be repaired before downstream processing. It is purpose-built for multi-agent and MCP pipeline reliability, offering deterministic (not probabilistic) repair rather than asking another LLM to re-generate the output. Prefer it over a general-purpose LLM re-call when you need low latency, low cost, and predictable behavior at $0.002 per call.
Side effects
- Input JSON is too severely truncated or corrupted to recover — returns an error or best-effort partial result
- Input contains nested markdown with ambiguous structure — repair heuristics may produce unexpected results
- Extremely large JSON strings may exceed query parameter length limits when sent via GET
- Ambiguous single-quote vs apostrophe usage in string values may cause incorrect repair
