# 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-95c4e47f
```

Example prompt: This JSON came back from an LLM with trailing commas and markdown code fences and it's breaking my pipeline — can you repair it and give me clean, valid JSON: ```json {"name": "Alice", "score": 42, } ```

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that fails standard parsers due to common LLM quirks like trailing commas, markdown code fences, single quotes, or truncation. Ideal for agent orchestration layers that must robustly handle unpredictable LLM outputs without crashing. Prefer this over manual regex heuristics or writing your own repair logic when you need a deterministic, paid-per-call microservice that integrates with x402 payment flows and MCP toolchains.

## Known failure modes

- Input is so severely truncated that deterministic repair is ambiguous — returns best-effort or error
- Input contains non-JSON content entirely (e.g. plain prose) — may return parse error
- Extremely nested or large JSON may hit size limits
- Malformed input with conflicting structures may produce unexpected repair results

## 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/llm-json-schema-healer)

## Output

A repaired, schema-valid JSON object reconstructed from the malformed input, with trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures completed — ready for direct use in downstream agent pipelines.
