# AgentDiet JSON Repair Endpoint

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

Repairs and cleans malformed or broken JSON strings, returning valid, corrected JSON with compression metadata.

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-endpoint-05ede931
```

Example prompt: Can you repair this broken JSON for me: '{"name": "Alice", "age": 30, "city": "New York"' — it's missing the closing brace and I need it to be valid JSON I can use downstream.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JSON repair service that returns corrected JSON along with compression/repair metrics. It is especially useful in agentic pipelines where LLM outputs, API responses, or user-supplied data may contain malformed JSON that must be sanitized before further processing. Prefer this over manual regex-based fixes or client-side parsing hacks when you need reliable structured output with minimal latency.

## Known failure modes

- Input JSON is so severely malformed that repair is not possible — returns error status
- Missing required 'input' parameter causes validation failure
- Unsupported HTTP method specified in 'method' field
- Empty or null raw_json query parameter results in no-op or error
- Network timeout or upstream service unavailability

## 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 valid JSON, a 'status' field (e.g. 'ok'), and an 'roi_proof' object containing compression metadata such as compression_ratio_pct indicating how much the input was compacted or corrected.
