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://shopify-intel.agentdiet.dev/v1/malformed-json-healer)
Output
A repaired, valid JSON object or string with all syntax errors resolved — trailing commas removed, single quotes replaced with double quotes, markdown fences stripped, and truncations recovered where possible — ready to be parsed and used downstream in an agent pipeline.
Example use cases
LLM output JSON cleanup in pipeline
“My agent just got back this malformed JSON from a language model and it's crashing the next step in my workflow — can you repair it into valid JSON? Here's the raw output: {"items": ["apple", "banana",], 'count': 2}”
Stripping markdown fences from AI response
“The model wrapped its JSON in triple backtick code fences and now my parser is failing — can you strip those out and give me back the clean JSON object?”
Fixing truncated JSON from a streaming LLM
“My streaming LLM cut off mid-response and I ended up with this truncated JSON that won't parse: {"user": "bob", "score": 95, "tags": ["vip" — can you try to repair it into something valid?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/malformed-json-healer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, rule-based JSON repair (not AI guessing) in a multi-agent or LLM pipeline where broken JSON from model outputs — trailing commas, single quotes, markdown fences, or truncations — is causing downstream parse failures. Prefer this over writing custom regex sanitization or calling a general-purpose LLM to fix JSON, as it is fast, low-cost ($0.002/call), and guaranteed to apply consistent repair rules without hallucinating new content.
Side effects
- Input JSON is so severely truncated or corrupted that deterministic repair is impossible — may return an error or best-effort partial result
- Input string is not JSON at all (e.g. plain text or binary) — returns a validation error
- Ambiguous structure where multiple valid repairs exist — endpoint picks one deterministically, which may not match original intent
- Empty or whitespace-only input — returns a validation error for missing required field
