# AgentDiet JSON Repair & Schema Validator

> AgentDiet JSON Repair & Schema Validator is a paid API for AI agents from agentdiet.dev, paid per call via x402 or MPP, $0.002/call, status unknown (last checked 2026-10-20).

Repairs malformed or broken JSON strings deterministically, normalizing them into valid, schema-conformant JSON

## Facts

- Price: $0.002/call
- Payment: x402, MPP
- Status: unknown
- Last checked: 2026-10-20

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 agentdiet-json-repair-schema-validator-0e1c2e88
```

Example prompt: Can you repair this broken JSON string for me — it's coming back malformed from a third-party API and failing to parse: '{name: "Alice", age: 30, active: true'

## When to prefer this

Choose this endpoint when you need deterministic, rule-based JSON repair rather than generative reformatting. Ideal when downstream systems require strict schema conformance and you cannot tolerate hallucinated field values from an LLM fix. Best for pipeline automation where JSON from external APIs, LLM outputs, or legacy systems arrives broken and must be reliably normalized before further processing.

## Known failure modes

- Input JSON too malformed to recover — returns error status
- Missing required 'input' or 'method' fields — returns validation error
- Empty or null raw_json query parameter — may return empty data
- Network timeout for large payloads
- Payment failure via x402 if USDC balance is insufficient

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object with a 'data' field containing the repaired and validated JSON, a 'status' field ('ok' on success), and a 'roi_proof' object showing compression or normalization metrics such as compression_ratio_pct.
