# 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 JSON outputs (trailing commas, markdown fences, single quotes) so multi-agent pipelines never crash.

## 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-e57f9519
```

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

## When to prefer this

Choose this endpoint when your multi-agent or LLM pipeline needs a deterministic, rule-based JSON repair step rather than a probabilistic LLM re-parse. Ideal when you need reproducible, auditable fixes for known LLM output defects like trailing commas, markdown fences, and single quotes, and when you cannot afford to re-prompt the LLM due to cost or latency constraints.

## Known failure modes

- Input JSON is so severely malformed it cannot be deterministically repaired — returns error or partial result
- Ambiguous truncation point where the intended structure cannot be inferred — may return best-guess repair
- Empty or whitespace-only input — returns validation error
- Input exceeds maximum length limits — returns truncation or rejection error
- Network timeout or service unavailability — returns HTTP 5xx

## 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/malformed-json-healer)

## Output

A JSON object containing the repaired, syntactically valid JSON — with all common LLM-induced defects (trailing commas, markdown fences, single quotes, truncated structures) deterministically fixed and ready to use in downstream pipeline steps.
