# 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

## 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-b273fdf2
```

Example prompt: This JSON string came back from my LLM and it's breaking my pipeline — it has trailing commas and markdown code fences around it. Can you repair it so it's valid JSON I can actually parse?

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that may contain common syntax errors like trailing commas, markdown code fences, or single quotes, and you need a deterministic (non-AI, non-probabilistic) repair rather than asking another LLM to fix it. Particularly valuable in production pipelines where reliability and predictability matter more than creative reconstruction.

## Known failure modes

- Input JSON is so severely malformed it cannot be deterministically repaired — returns error
- Input string is not JSON at all (e.g. plain text or binary) — validation fails
- Truncation is too severe to infer intended structure — ambiguous repair result
- Payment not processed via x402 — 402 response returned before repair attempt

## 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-validator)

## Output

Returns a repaired, syntactically valid JSON object with malformed elements corrected — trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed — ready for use in downstream agent or pipeline steps.
