# AgentDiet JSON Repair Endpoint

> AgentDiet JSON Repair Endpoint is a paid API for AI agents from arxiv-digest.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 output via a GET request

## Facts

- Endpoint: GET https://arxiv-digest.agentdiet.dev/v1/json-repair?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402, MPP
- Status: unknown
- Last checked: 2026-10-20

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_XSe-Q5drlT6FOmzxhmVtM

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-b65fdaa8
```

Example prompt: Can you fix this broken JSON for me? It has missing quotes and an extra comma: {name: 'Alice', age: 30,}

## When to prefer this

Choose this endpoint when you have a malformed or syntactically invalid JSON string that needs to be repaired into parseable JSON, especially when generated by LLMs or scraped from unstructured sources. It is particularly useful in agentic pipelines where downstream steps require valid JSON but upstream sources are unreliable. Prefer it over manual regex fixes or custom parsers for its speed and ROI metrics.

## Known failure modes

- Input JSON is so malformed it cannot be recovered — returns error status
- Missing required 'raw_json' query parameter — returns validation error
- Input is not JSON at all (e.g. plain text or binary) — unpredictable repair output
- Network timeout if input string is very large
- HTTP 402 Payment Required if USDC payment via x402 is not provided or fails

## 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, valid JSON, a 'status' field indicating success ('ok'), and an 'roi_proof' object showing the compression_ratio_pct achieved during repair/normalization.
