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://domain-osint.agentdiet.dev/v1/json-repair)
Output
A JSON object containing the repaired, syntactically valid JSON, recovered from the malformed input string — ready for downstream parsing and processing in agent pipelines.
Example use cases
LLM pipeline JSON crash prevention
“The language model just returned this malformed JSON with a trailing comma and I need it fixed before it crashes my pipeline: {"status": "ok", "items": [1, 2, 3,]}”
Markdown-wrapped agent response cleanup
“My agent returned JSON wrapped in markdown code fences and it won't parse — strip the fences and fix it for me: ```json
{"user": 'bob', "score": 99}
```”
Recovering truncated LLM JSON output
“The LLM got cut off mid-response and gave me this truncated JSON — see if you can repair it into something valid: {"results": [{"id": 1, "name": "foo"}, {"id": 2”
Technical details
Endpoint
POSThttps://domain-osint.agentdiet.dev/v1/json-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline or LLM workflow produces malformed, truncated, or markdown-wrapped JSON that needs deterministic (rule-based, not AI-guessed) repair before downstream processing. Ideal for production pipelines where reliability and idempotency are critical and you need consistent fix behavior across retries via Idempotency-Key headers.
Side effects
- Input is too severely corrupted to deterministically repair — returns error indicating unrecoverable JSON
- Input string is empty or missing — returns 400-level validation error
- JSON is so ambiguous that deterministic repair is not possible without semantic inference — may return partial result or error
