# Deterministic A2A Broken-JSON Repair & Schema Validator

> Deterministic A2A Broken-JSON Repair & Schema Validator is a paid API for AI agents from domain-osint.agentdiet.dev, paid per call via MPP, $0.002/call, status unknown (last checked 2026-10-21).

Repairs truncated, malformed, or markdown-wrapped 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 domain-osint-agentdiet-dev-deterministic-a2a-broken-json-repair-be6effd6
```

Example prompt: This LLM response came back as broken JSON with trailing commas and markdown code fences — can you repair it so I can use it downstream? Here's the raw string: ```{"name": "Alice", "age": 30,}```

## When to prefer this

Choose this endpoint when your multi-agent or LLM pipeline frequently receives malformed, truncated, or markdown-wrapped JSON that breaks downstream parsers. It is especially valuable when you need deterministic (not probabilistic) repair, want to avoid writing custom JSON-cleaning logic, or are operating in a pay-per-call x402 micropayment context. Prefer this over manual regex cleaning or LLM re-prompting when reliability and consistency are critical.

## Known failure modes

- Input is so severely malformed that repair is impossible — returns error indicating unparseable input
- Non-JSON content passed as raw_json (e.g. plain text, binary) — may return parsing error or empty object
- Extremely long truncated JSON where context is insufficient to infer missing structure — partial repair or failure
- Missing required raw_json parameter — returns 400 or validation error
- Payment not fulfilled (x402) — returns 402 Payment Required 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://domain-osint.agentdiet.dev/v1/structured-output)

## Output

A repaired, valid JSON object parsed from the malformed input string. The endpoint deterministically corrects issues like trailing commas, markdown code fences, single quotes, and truncation, returning a clean structured object ready for downstream agent or pipeline consumption.
