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://cve-intel.agentdiet.dev/v1/structured-output)
Output
A repaired, valid JSON object that has been cleaned of common LLM output artifacts including trailing commas, markdown code fences (backticks), single quotes, and truncation issues — returned as a parseable JSON object ready for downstream agent consumption
Example use cases
Fix crashed agent pipeline JSON
“My LLM just returned this mangled JSON with trailing commas and backtick fences and my downstream agent is crashing — can you repair it into valid JSON so I can continue the workflow? Here's the broken output: ```json {'status': 'ok', 'items': ['a', 'b',],}```”
Sanitize single-quoted LLM response
“The AI response I got back uses single quotes instead of double quotes and has a trailing comma — can you fix this so it's valid JSON I can actually parse? Raw string: {'model': 'gpt-4', 'confidence': 0.95,}”
Recover truncated JSON from streaming output
“My streaming LLM response got cut off halfway through and now the JSON is incomplete and unparseable. Can you deterministically repair this truncated JSON and give me back a valid object? Here it is: {"results": [{"id": 1, "name": "foo"}, {"id": 2, "nam”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/structured-output?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline receives malformed, truncated, or markdown-wrapped JSON from an LLM and needs deterministic (not AI-based) repair before passing data to a downstream tool. Ideal for production agent orchestration where reliability matters and you cannot afford nondeterministic re-prompting. Prefer over regex-based manual fixes when the malformations are compound (e.g. both trailing commas AND markdown fences AND single quotes at once).
Side effects
- JSON is too severely corrupted to deterministically repair — returns error indicating repair was not possible
- Input string is not JSON at all (e.g. plain prose) — may return parse failure
- Ambiguous truncation that could resolve to multiple valid structures — may return best-guess or error
- Very large malformed JSON strings may exceed query parameter length limits
- Missing required raw_json parameter returns 400 error
