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 reconstructed from the malformed input, with all syntax errors corrected including trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed.
Example use cases
Fixing LLM pipeline broken JSON
“The language model just returned this malformed JSON with a trailing comma and single quotes — it's crashing my downstream parser. Can you repair it and give me back valid JSON? Raw output: {'user': 'bob', 'score': 99,}”
Stripping markdown fences from agent output
“My agent wrapped its JSON response in markdown code fences and now I can't parse it. Here's the raw string: ```json
{"status": "ok", "items": [1, 2, 3]}
``` — please strip the fences and return clean JSON.”
Recovering truncated JSON from timeout
“The LLM timed out mid-generation and gave me a truncated JSON that's missing the closing brackets. Can you deterministically repair this so my workflow can continue? Here's what I got: {"results": [{"id": 1, "name": "foo"}”
Technical details
Endpoint
POSThttps://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 repair rather than probabilistic re-generation. Ideal for production pipelines where reliability matters and you cannot afford to re-query the LLM. Prefer this over manual parsing heuristics or custom code when you need a standardized, repeatable fix across trailing commas, single quotes, and markdown fences in one call.
Side effects
- Input JSON is so severely malformed it cannot be deterministically repaired — returns error indicating repair failure
- Input string is empty or below minimum length — returns 400 validation error
- The malformed content is ambiguous enough that repair introduces incorrect structure — repaired JSON may not match original intent
- Network timeout or service unavailability returns 5xx error
- Payment not attached or insufficient — returns HTTP 402 payment required
