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://agentdiet.dev/v1/schema-repair)

Output

A repaired, valid JSON object derived from the malformed input, with common LLM-output issues like trailing commas, markdown code fences, single quotes, and truncation corrected so downstream agents or parsers can safely consume it.

Example use cases

Fix LLM output in agent pipeline

“My orchestration agent got a response from a sub-agent but the JSON is malformed — it has trailing commas and single quotes instead of double quotes. Can you repair this so the next step in my pipeline doesn't crash? Raw: {'items': ['a', 'b',], 'count': 2,}”

Strip markdown fences from LLM JSON

“The LLM returned JSON wrapped in triple backticks and it's breaking my parser. Can you strip the markdown fences and give me clean, valid JSON? Here's what I got: ```json {"result": "ok", "score": 0.95} ```”

Validate repaired JSON against expected structure

“I have a truncated JSON blob from an LLM that got cut off mid-response — it ends abruptly without closing brackets. Can you repair it and validate that it still has the required fields 'name' and 'status'? Here it is: {"name": "Order-42", "status": "pending", "items": ["widget”

When to prefer

Choose this endpoint when your multi-agent pipeline receives JSON from an LLM that fails to parse due to common formatting errors like trailing commas, markdown fences, single quotes, or truncation. It is a fast, deterministic (non-AI) repair layer, making it reliable and cheap for high-volume pipelines. Prefer it over retrying the LLM when the JSON is structurally close to valid and just needs cleanup.

Side effects

Input JSON is so severely corrupted that deterministic repair is impossible — returns error indicating irreparable input
Missing required 'raw_json' query parameter — returns validation error
Input is not JSON at all (e.g. plain prose) — may return error or attempt best-effort repair with low confidence
Extremely long or deeply nested JSON may exceed processing limits
