# Deterministic A2A Broken-JSON Repair & Schema Validator

> Deterministic A2A Broken-JSON Repair & Schema Validator is a paid API for AI agents from github-audit.agentdiet.dev, paid per call via MPP, $0.002/call, status unknown (last checked 2026-10-21).

Repairs truncated or malformed LLM-generated JSON (trailing commas, markdown fences, single quotes) to prevent multi-agent pipeline crashes

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-a963c10e
```

Example prompt: The JSON I got back from the LLM is broken — it has trailing commas and markdown code fences wrapping it. Can you clean it up and give me valid JSON? Here it is: ```json {"name": "Alice", "age": 30,} ```

## When to prefer this

Use this endpoint when you have LLM or agent-generated JSON that is syntactically broken and need a deterministic (non-AI) fix before passing it downstream in a pipeline. Prefer it over prompt-based JSON repair when you need speed, consistency, and no hallucination risk. Ideal for multi-agent architectures where structured outputs from one model feed into another component that requires strict JSON compliance.

## Known failure modes

- Input JSON is too severely corrupted to recover — returns error indicating repair not possible
- Input string is empty or missing the raw_json parameter — returns 400 validation error
- JSON is structurally ambiguous (e.g. multiple valid repairs possible) — may return best-effort result or error
- Network timeout or service unavailability — returns 5xx error

## 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/structured-output)

## Output

Returns a repaired, valid JSON object parsed from the malformed input, with common issues like trailing commas, markdown code fences, single quotes, and truncation corrected deterministically.
