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://mcp-compiler.agentdiet.dev/v1/llm-json-schema-healer)
Output
Returns a repaired, valid JSON object where all common LLM-induced malformations — trailing commas, markdown fences, single quotes, truncation — have been deterministically fixed and the output is parseable.
Example use cases
Fix LLM JSON in agent pipeline
“My AI agent just returned this malformed JSON with a trailing comma and single quotes that's crashing my pipeline — can you repair it and give me back valid JSON: {'user': 'Bob', 'score': 42,}”
Strip markdown fences from LLM output
“The model wrapped its JSON in triple-backtick markdown fences and now it won't parse — can you strip that out and return clean valid JSON? Here's the output: ```json
{"status": "ok", "count": 5}
```”
Recover truncated JSON from long generation
“My LLM got cut off mid-response and the JSON is incomplete and won't load — can you deterministically repair this truncated JSON so I can continue processing: {"items": ["apple", "banana"”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/llm-json-schema-healer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent or LLM pipeline is producing malformed JSON outputs that need deterministic (not generative/AI-based) repair — especially for trailing commas, markdown code fences, single quotes, or truncated outputs. Prefer this over custom parsing logic when you need a reliable, pay-per-call microservice that handles the most common LLM JSON failure modes without hallucinating new content.
Side effects
- Input JSON is too severely corrupted to deterministically recover — returns error
- Input string is not JSON-like at all — returns parsing error
- Ambiguous truncation where multiple valid repairs exist — may return best-guess repair
- Empty or whitespace-only input — returns validation error
