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).
Repairs truncated or malformed LLM-generated JSON (trailing commas, markdown fences, single quotes) so multi-agent pipelines receive valid, schema-conformant output.

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/llm-json-schema-healer)
Output
A repaired, valid JSON object where truncations are closed, trailing commas removed, markdown fences stripped, and single quotes converted to double quotes — ready for programmatic parsing without errors.
Example use cases
Fix crashed multi-agent pipeline output
“My agent pipeline just broke because the upstream LLM returned this garbled JSON with a trailing comma and backtick fences — can you repair it so I can continue processing: '```json\n{"status": "ok", "results": [1, 2, 3,]}\n```'?”
Normalize single-quoted LLM JSON response
“The model returned JSON using single quotes instead of double quotes and it won't parse — please fix this so it's valid JSON: "{'user': 'bob', 'score': 42}"”
Recover truncated LLM JSON mid-stream
“My LLM response got cut off mid-object and the JSON is incomplete — something like '{"report": {"title": "Q2 Summary", "sections": [' — can you repair and close it so I get a valid JSON object back?”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/llm-json-schema-healer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent or LLM pipeline receives structured JSON outputs that are frequently malformed due to model truncation, markdown formatting, or non-strict quoting — and you need a deterministic, rule-based fix rather than asking the LLM to re-generate. Prefer it over regex heuristics or manual post-processing when reliability and auditability matter.
Side effects
- Input JSON is so severely malformed that deterministic repair is ambiguous — endpoint may return a best-effort result or an error indicating the string cannot be recovered
- Empty or whitespace-only raw_json input returns a validation error
- Non-JSON input (plain text, binary data) cannot be meaningfully repaired
- Extremely long truncated inputs may time out or return partial repairs
- Network or payment (x402) authentication failures return HTTP 402 or 5xx
