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://x402-audit.agentdiet.dev/v1/json-repair)
Output
Returns a repaired, valid JSON object parsed from the malformed input. The response contains the cleaned JSON with all syntax errors corrected — trailing commas removed, markdown fences stripped, single quotes normalized to double quotes, and truncated structures closed where possible.
Example use cases
LLM pipeline JSON crash prevention
“The structured output from my last agent step has trailing commas and is wrapped in a ```json markdown block — it's breaking my downstream parser. Can you repair it so it's clean, valid JSON I can feed into the next step?”
Single-quote JSON fix for agent workflow
“My LLM returned JSON using single quotes instead of double quotes and some missing brackets. Fix it so it's valid JSON before I pass it to the next agent in the pipeline.”
Truncated API response recovery
“I got a truncated JSON response that got cut off mid-string and has unclosed braces. Can you repair it deterministically and return whatever valid JSON can be recovered?”

Endpoint
POSThttps://x402-audit.agentdiet.dev/v1/json-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline receives malformed, truncated, or markdown-wrapped JSON from an LLM and needs a deterministic, paid-per-call repair service rather than a local library. Ideal for production agentic workflows where reliability matters and you want a battle-tested remote repair service with x402 micropayment support, especially if you're already using the agentdiet.dev B2A hub for other capabilities.
Side effects
- Input is so corrupted that no valid JSON can be recovered — returns error with details
- Input JSON is empty or null — returns 400 validation error
- Payment not completed via x402 — returns HTTP 402 Payment Required
- Idempotency-Key collision with different payload — may return cached prior result
- Input exceeds size limits — returns 413 or similar error
