## 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 github-audit-agentdiet-dev-deterministic-a2a-broken-json-repair-758a9f35 -d '<json body>'
```

Example prompt: The LLM response I just got back has trailing commas, markdown code fences, and single quotes — it's not valid JSON. Can you run it through the JSON repair service and give me back a clean, parseable object?

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that fails to parse due to common formatting errors like markdown code fences, trailing commas, single quotes, or truncation. It is deterministic (not AI-based), making it predictable and auditable for production pipelines. Prefer it over custom regex-based repair logic when you need a reliable, hosted microservice that handles the full range of common LLM JSON malformations in a single call.

## Known failure modes

- Input too severely truncated or garbled to reconstruct valid JSON — returns error or best-effort partial object
- Input is not JSON at all (e.g. plain prose) — may return error or empty object
- Network/payment issues causing 402 or timeout
- Ambiguous repair decisions where multiple valid interpretations exist — picks one deterministically but may not match original intent

## 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://github-audit.agentdiet.dev/v1/json-fix)

## Output

A repaired, valid JSON object derived from the malformed input. The response contains the corrected JSON with markdown fences removed, trailing commas stripped, single quotes converted to double quotes, and truncated structures closed — ready for downstream parsing by any agent or pipeline.
