# Deterministic A2A Broken-JSON Repair & Schema Validator

> Deterministic A2A Broken-JSON Repair & Schema Validator is a paid API for AI agents from sec-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 sec-intel-agentdiet-dev-deterministic-a2a-broken-json-repair-schema-584efd42
```

Example prompt: The JSON my LLM just returned has trailing commas and is wrapped in markdown code fences — can you repair it so it's valid JSON I can parse? Here's the raw output: ```json {"name": "Alice", "age": 30,} ```

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives malformed, truncated, or LLM-generated JSON that fails standard JSON.parse() — especially when you need deterministic, reproducible fixes (not probabilistic LLM re-generation) and need to handle common LLM artifacts like markdown fences, trailing commas, and single-quoted keys at low per-call cost ($0.002).

## Known failure modes

- Input JSON is so severely corrupted that deterministic repair is impossible — returns error indicating unrecoverable malformation
- Input string is empty or too short to infer structure
- JSON structure is ambiguous after repair and multiple valid interpretations exist
- Rate limiting or payment failure for x402 micropayment

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

## Output

Returns a repaired, schema-valid JSON object with the fixed JSON string, ready for programmatic consumption by downstream agents or pipeline steps
