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

Repairs and normalizes malformed JSON strings, returning cleaned valid JSON with a compression/ROI proof metric

## Facts

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-f45df64e
```

Example prompt: I have this broken JSON string that won't parse — can you run it through AgentDiet's JSON repair to fix the syntax errors and give me back valid, clean JSON?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call JSON repair service accessible via simple GET request with USDC micropayment (x402). Prefer it over client-side JSON parsers when you need a reliable cloud-based fix for LLM outputs, scraped data, or corrupted API responses, especially in agent pipelines where bad JSON would otherwise break downstream steps.

## Known failure modes

- Input JSON is too malformed to be repaired — returns error status
- Missing required 'raw_json' query parameter — returns validation error
- Network timeout or service unavailability
- Input exceeds maximum size limits — returns size error

## 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 JSON, a 'status' field ('ok' on success), and a 'roi_proof' object containing 'compression_ratio_pct' indicating how much the input was cleaned/compressed as a percentage.
