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-fix)
Output
A repaired, valid JSON object with all syntax errors corrected — trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed — ready for safe downstream parsing in agent pipelines.
Example use cases
Fix LLM response in agent pipeline
“The language model just returned a JSON blob wrapped in triple backticks with a trailing comma — fix it so my downstream parser can read it without crashing.”
Sanitize single-quoted JSON from model
“I got this JSON back from the AI but it's using single quotes instead of double quotes and has some extra commas — can you clean it up into proper valid JSON?”
Recover truncated JSON output
“The model's JSON output got cut off mid-structure and now my pipeline is failing — repair whatever you can from this truncated JSON string and give me back something parseable.”
Technical details
Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/json-fix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline needs a deterministic, fast, non-AI-based JSON repair — especially when LLM outputs frequently contain markdown fences, trailing commas, or single quotes. Prefer this over writing custom regex sanitizers or calling another LLM to fix JSON, as it provides consistent, reproducible repairs without hallucination risk.
Side effects
- JSON is so severely truncated that repair is impossible — returns error or best-effort partial object
- Input is not JSON at all (e.g. plain text or binary) — may return error or empty object
- Extremely large JSON strings may hit query parameter length limits since raw_json is passed as a GET query parameter
- Ambiguous structure in deeply nested truncated JSON may result in incorrect repair assumptions
