## 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 email-verify-agentdiet-dev-deterministic-a2a-broken-json-repair-c77df94a
```

Example prompt: The LLM just returned this broken JSON with trailing commas and markdown code fences — can you repair it into valid JSON so I can pass it to the next step? Here's the raw string: ```{"name": "Alice", "age": 30,}```

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that may contain common syntax errors (trailing commas, markdown fences, single quotes, minor truncation) and you need a deterministic, fast fix before passing the data downstream. Prefer it over custom parsing logic when you want a reliable, hosted microservice that handles the most common LLM JSON output failure modes without writing your own sanitizer.

## Known failure modes

- Input JSON too severely truncated to deterministically repair — returns error or best-effort partial result
- Input is not JSON-like at all — may return an error indicating non-parseable input
- Ambiguous repair cases where multiple valid completions exist — deterministic heuristic may choose unexpected structure
- Empty or whitespace-only raw_json — returns validation error for missing/empty input

## 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://email-verify.agentdiet.dev/v1/json-normalizer)

## Output

A JSON object containing the repaired and normalized version of the input string, with all syntax errors corrected — trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncations resolved where deterministically possible.
