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://workflows.agentdiet.dev/v1/json-normalizer)
Output
A parsed, valid JSON object reconstructed from the malformed input — trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed — ready for downstream consumption in agent pipelines.
Example use cases
Fix LLM output in agent pipeline
“The language model just returned this JSON with a trailing comma and it's breaking my pipeline — clean it up so it parses correctly: {"items": ["apple", "banana",], "count": 2}”
Strip markdown fences from JSON
“My agent got back a response wrapped in triple backticks with 'json' as the language tag — can you strip the markdown fencing and give me just the valid JSON object inside?”
Repair single-quoted JSON from scraper
“I scraped some data and the JSON is using single quotes instead of double quotes, which makes it invalid — can you convert it to proper JSON so I can process it? Here's the string: {'user': 'bob', 'score': 42}”

Endpoint
GEThttps://workflows.agentdiet.dev/v1/json-normalizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent pipeline receives LLM-generated or scraped JSON that fails standard JSON.parse() due to common formatting issues like trailing commas, markdown code fences, single quotes, or truncation. It is purpose-built for multi-agent and A2A workflows where deterministic, reliable JSON normalization is critical and crashing is not acceptable.
Side effects
- Input is so severely corrupted that deterministic repair is impossible, returning an error
- Input string is empty or missing the raw_json parameter
- JSON structure is ambiguous beyond repair (e.g. completely unparseable non-JSON text)
- Extremely large or deeply nested JSON may time out
