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://shopify-intel.agentdiet.dev/v1/json-repair)
Output
A repaired, valid JSON object returned as a structured response. The endpoint deterministically corrects common LLM output defects including trailing commas, markdown code fences, single-quoted keys/values, and truncation issues, returning a clean, parseable JSON payload.
Example use cases
LLM pipeline JSON crash recovery
“My language model just returned this malformed JSON with trailing commas and it's breaking my downstream agent — can you fix it so I can keep the pipeline running? Raw output: {"status": "ok", "items": ["a", "b",], }”
Markdown fence stripping for agent handoff
“The model wrapped its response in triple-backtick markdown fences and now my agent can't parse it — can you strip the fences and repair any issues so I get a clean JSON object back?”
Single-quote JSON normalization
“I got a JSON response that uses single quotes instead of double quotes and it's failing validation — can you convert it to proper JSON? Here it is: {'user': 'bob', 'active': true}”

Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/json-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent pipeline receives JSON from an LLM or external agent that is malformed, truncated, or wrapped in markdown, and you need a deterministic (non-AI) fix rather than another LLM pass. Ideal for production pipelines where reliability and cost predictability matter — at $0.002/call it is cheaper than re-invoking an LLM. Prefer this over manual parsing or regex hacks when you encounter trailing commas, single quotes, or markdown fences consistently in LLM outputs.
Side effects
- Input JSON is so severely malformed it cannot be deterministically repaired — returns error indicating unrecoverable input
- Empty or missing raw_json field — returns 400 validation error
- Input exceeds maximum payload size limits — returns size-related error
- Payment not completed via x402 — returns HTTP 402 with payment required details
