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://github-audit.agentdiet.dev/v1/repair)
Output
A repaired, valid JSON object that has been cleaned of common malformations such as trailing commas, markdown code fences, single quotes, and truncation artifacts, ready for downstream parsing and processing in multi-agent pipelines.
Example use cases
Fix LLM output in agent pipeline
“My AI agent just returned this malformed JSON with a trailing comma and it's crashing my downstream processor — please repair it: {"status": "ok", "items": ["a", "b",]}”
Strip markdown fences from JSON response
“The model wrapped its JSON in triple backtick markdown fences again and now my parser is choking — can you clean this up and give me valid JSON? Here's the raw output: ```json
{"result": "success", "count": 42}
```”
Repair single-quoted JSON from legacy system
“I'm getting JSON back from an old system that uses single quotes instead of double quotes and it won't parse — fix this string for me: {'user': 'bob', 'active': true}”
Technical details
Endpoint
POSThttps://github-audit.agentdiet.dev/v1/repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that fails standard parsing due to common LLM quirks like trailing commas, markdown wrapping, or single quotes. Ideal for automated pipelines where you need deterministic, crash-free JSON repair without human intervention. Prefer this over custom regex heuristics when you want a managed, paid API with idempotency guarantees.
Side effects
- Input JSON is so severely malformed it cannot be deterministically repaired — returns error with details
- Empty or null raw_json input returns validation error
- Input that is not JSON at all (e.g. plain prose) may return unparseable error
- Extremely long or deeply nested JSON may hit size limits
