LLM JSON Repair & Schema Validator
LLM JSON Repair & Schema Validator is a paid API for AI agents from company-enrich.agentdiet.dev, paid per call via MPP, $0.002/call, status unknown (last checked 2026-10-21).
Deterministically repairs malformed, truncated, or markdown-wrapped LLM JSON outputs (trailing commas, markdown fences, single quotes) so multi-agent pipelines can safely consume them.

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://company-enrich.agentdiet.dev/v1/llm-json-schema-healer)
Output
Returns a repaired, valid JSON object where the input malformed, truncated, or markdown-wrapped JSON string has been deterministically fixed — trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and missing closing brackets/braces added as needed.
Example use cases
Fix crashed agent pipeline JSON
“The agent in my pipeline returned malformed JSON with single quotes and a trailing comma — something like {'company': 'OpenAI', 'founded': 2015,} — can you repair it into valid JSON so the next step doesn't crash?”
Strip markdown fences from LLM output
“My LLM wrapped its JSON response in triple backtick markdown fences and now my parser is breaking. Here's the raw output: ```json {"result": true} ``` — please strip the fences and return clean parseable JSON.”
Heal truncated JSON from long generation
“My model got cut off mid-generation and produced a truncated JSON object that's missing closing braces. Can you repair this broken JSON so it's valid: {"items": [{"id": 1, "name": "widget"”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/llm-json-schema-healer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline or LLM workflow is receiving JSON outputs that are syntactically broken due to common LLM failure modes (trailing commas, markdown wrapping, single quotes, truncation) and you need a fast, deterministic fix before downstream parsing. Prefer this over a general-purpose JSON library when the errors are specifically LLM-output patterns and you need a hosted, pay-per-call solution compatible with x402/MCP agent architectures.
Side effects
- Input JSON too severely corrupted to deterministically repair — returns error indicating repair not possible
- Empty or whitespace-only raw_json input — validation error
- Input exceeds maximum length limits — truncation or rejection error
- Ambiguous structure where multiple valid repairs exist — may return one interpretation without warning
