Deterministic A2A Broken-JSON Repair & Schema Validator
Deterministic A2A Broken-JSON Repair & Schema Validator is a paid API for AI agents from cve-intel.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 so multi-agent pipelines can parse them without crashing

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://cve-intel.agentdiet.dev/v1/repair)
Output
Returns a repaired, valid JSON object that has been cleaned of common LLM-output defects including trailing commas, markdown code fences, single quotes, and truncation artifacts — ready to be parsed by downstream agents or systems
Example use cases
Fix LLM JSON before downstream processing
“My language model returned this JSON but it has a trailing comma and it's wrapped in markdown fences — can you clean it up so I can pass it to the next step? Here's the raw string: ```{"status": "ok", "items": [1, 2, 3,]}```”
Recover truncated agent response JSON
“The agent pipeline got cut off mid-response and returned this truncated JSON: {"user": "alice", "score": 98, "tags": ["premium" — can you repair it into something parseable?”
Normalize single-quote JSON from GPT output
“GPT gave me back JSON using single quotes instead of double quotes and I can't parse it — can you fix this: {'name': 'Bob', 'active': true} into proper valid JSON?”

Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, rule-based JSON repair (not heuristic or ML-based) for LLM outputs in automated multi-agent pipelines where reliability and predictability matter most. Ideal when you encounter trailing commas, markdown fences, or single-quote JSON from language models and need a fast, cheap ($0.002/call) fix before passing data downstream.
Side effects
- Input JSON is too severely malformed to repair deterministically — returns error indicating unrecoverable syntax
- Input is not JSON at all (e.g. plain prose) — may return error or unexpected output
- Extremely long truncated payloads may not be restorable to original intent
- Missing required raw_json parameter returns 400 or validation error
- Payment not completed via x402 returns 402 Payment Required
