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://github-audit.agentdiet.dev/v1/schema-repair)
Output
Returns a repaired, valid JSON object parsed from the originally malformed input string, with common LLM output artifacts (trailing commas, markdown fences, single quotes, truncations) corrected deterministically.
Example use cases
Fixing LLM output in agent pipeline
“The language model in my pipeline returned JSON wrapped in triple backticks with a trailing comma — clean it up and give me valid parseable JSON: ```json
{"status": "ok", "items": [1, 2, 3,]}
```”
Repairing truncated API response
“My agent received a truncated JSON string that got cut off mid-value: '{"user": "bob", "role": "adm' — can you repair this and give me back valid JSON?”
Sanitizing single-quoted JSON from chatbot
“A chatbot returned JSON using single quotes instead of double quotes like {'key': 'value', 'count': 5} — fix it so I can pass it to my downstream service.”

Endpoint
GEThttps://github-audit.agentdiet.dev/v1/schema-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, rule-based JSON repair rather than AI-based inference — particularly in multi-agent pipelines where LLM outputs frequently contain markdown fences, trailing commas, or single quotes and you need a reliable, cheap, low-latency fix before passing data downstream.
Side effects
- Input JSON is too severely malformed to repair deterministically — returns error or partial result
- raw_json parameter missing or empty — returns 400 validation error
- Input is not JSON-like at all (plain text, HTML) — repair may fail or return unexpected structure
- Payment failure via x402 — returns 402 Payment Required
