# Deterministic A2A Broken-JSON Repair & Schema Validator

> Deterministic A2A Broken-JSON Repair & Schema Validator is a paid API for AI agents from cve-intel.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

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 cve-intel-agentdiet-dev-deterministic-a2a-broken-json-repair-schema-17ccd1f1
```

Example prompt: This JSON came back from the LLM with trailing commas, markdown fences, and single quotes — can you run it through the JSON repair service and give me back clean, valid JSON? Here's the raw string: ```{'name': 'Alice', 'age': 30,}```

## When to prefer this

Choose this endpoint when an LLM or AI agent in your pipeline is returning syntactically invalid JSON that breaks downstream parsers — especially when you need a deterministic (non-AI) fix for issues like trailing commas, markdown code fences, single quotes, or truncated objects. Prefer this over regex hacks or writing your own repair logic when reliability across edge cases matters in a multi-agent workflow.

## Known failure modes

- Input JSON is so severely malformed that deterministic repair is not possible — returns error
- Empty or null raw_json parameter — returns validation error
- Input is not JSON at all (e.g. plain text or binary) — may return unparseable result
- Payment not processed (HTTP 402) — endpoint requires x402 micropayment before processing

## 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://cve-intel.agentdiet.dev/v1/schema-repair)

## Output

Returns a repaired, valid JSON object with syntax errors corrected — trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed — ready for downstream consumption in agent pipelines.
