## 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 cve-intel-agentdiet-dev-deterministic-a2a-broken-json-repair-schema-6c872ebd
```

Example prompt: This LLM response came back with a trailing comma and markdown fences around the JSON — can you clean it up and give me valid JSON I can actually parse? Here it is: ```{"name": "Alice", "age": 30,}```

## When to prefer this

Choose this endpoint when you need deterministic, rule-based JSON repair (not probabilistic LLM re-generation) for common LLM output corruption patterns like trailing commas, markdown fences, and single quotes. It is ideal for hardening multi-agent pipelines where you need reliable structured output without re-querying the upstream model. Prefer this over manual parsing hacks or asking the LLM to re-format when you need a consistent, low-latency fix that can be called programmatically.

## Known failure modes

- Input is so severely malformed that deterministic repair is not possible — returns error indicating unrecoverable JSON
- Empty or whitespace-only raw_json input — returns validation error for minLength constraint
- JSON is actually valid already — passes through unchanged
- Extremely long input may hit query string length limits since the parameter is passed via GET query

## 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/json-normalizer)

## Output

A repaired, valid JSON object that has had common LLM output issues fixed — including trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed — ready for downstream parsing or schema validation.
