## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability shopify-intel-agentdiet-dev-deterministic-a2a-broken-json-repair-991f500e
```

Example prompt: This JSON string from the LLM output is broken — it has trailing commas and markdown code fences wrapping it — can you repair it into valid JSON so the pipeline doesn't crash? Here it is: ```json {"name": "Alice", "age": 30,} ```

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives JSON from an LLM or AI model that has common structural defects like trailing commas, markdown code fences, single quotes, or truncation — and you need a fast, deterministic (not generative) fix rather than asking another LLM to rewrite the output. Ideal for lightweight, reliable pre-processing steps in automated pipelines where correctness and speed matter more than AI-powered inference.

## Known failure modes

- Input JSON is so severely malformed that deterministic repair is impossible, returning an error response
- Empty or whitespace-only raw_json input triggers a validation error
- JSON that is actually valid but semantically incorrect cannot be detected or corrected
- Extremely long or deeply nested JSON may hit processing limits
- Network timeout if the service is unavailable

## 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/repair)

## Output

A JSON object containing the repaired, valid JSON — converting the malformed input (trailing commas removed, markdown fences stripped, single quotes converted to double quotes, truncated structures closed) into a well-formed, parseable JSON value ready for downstream consumption.
