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://alpha-stream.agentdiet.dev/v1/json-normalizer)
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 downstream parsing.
Example use cases
Fix LLM output before downstream agent
“My AI pipeline just produced this malformed JSON with a trailing comma and single quotes — can you repair it so the next agent doesn't crash: {'user': 'Bob', 'score': 42,}?”
Strip markdown fences from model response
“The model wrapped its JSON in markdown code fences and now my parser is failing — please normalize this into clean JSON: ```json
{"status": "ok", "count": 5}
```”
Recover truncated JSON from streaming LLM
“I got a truncated JSON response mid-stream from the LLM and it's missing the closing brackets — can you repair and complete it so it's valid: {"results": [{"id": 1, "name": "foo"?”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/json-normalizer?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 formatting errors like trailing commas, markdown code fences, or single quotes. It is especially valuable in agentic workflows where a crashed JSON parser would halt the entire pipeline, or when consuming streaming LLM output that may be truncated. Prefer this over custom pre-processing code when you need a deterministic, low-latency, drop-in repair step with a consistent output contract.
Side effects
- JSON too severely malformed to deterministically repair — returns error or best-effort partial result
- Empty or missing raw_json parameter — returns validation error
- Input that is not JSON at all (e.g. plain prose) — may return error or unexpected output
- Ambiguous truncation where multiple valid completions exist — may return arbitrary completion
