## 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-fee515ab
```

Example prompt: This LLM output came back as broken JSON with trailing commas and markdown code fences — can you run it through the JSON repair service and give me back a clean, parseable object? Here's the raw string: ```{"name": "Alice", "score": 42,}```

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that is syntactically invalid and must be repaired before downstream processing. Ideal when you need deterministic, rule-based repair (not generative re-parsing) of common artifacts like trailing commas, markdown fences, single quotes, or minor truncation. Prefer this over asking an LLM to re-parse broken JSON when you want predictable, low-cost, low-latency fixes without consuming additional LLM tokens.

## Known failure modes

- JSON is too severely malformed or truncated to deterministically repair — returns error or best-effort partial result
- Input is not JSON-like at all (plain text, HTML) — may return error or unexpected output
- Extremely large raw_json strings may hit query string length limits when sent as GET parameter
- Ambiguous repair cases where multiple valid completions exist — deterministic repair may choose a non-intended path

## 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/repair)

## Output

Returns a repaired, valid JSON object that has been cleaned of common LLM output artifacts including trailing commas, markdown code fences, single-quoted keys/values, and truncation — ready to be parsed or passed downstream in an agent pipeline
