## 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 gocreative-json-validate-cc09337a -d '<json body>'
```

Example prompt: Can you check if this string is valid JSON and tell me what's wrong with it if not: '{"name": "Alice", "age": 30, "active": true}'?

## When to prefer this

Use this endpoint when you need to programmatically validate JSON syntax before processing or storing it, especially in agentic workflows where downstream systems expect well-formed JSON. Prefer this over manual parsing when you want structured error feedback with no API key or signup required, paying only $0.005 USDC per call.

## Known failure modes

- Empty or missing input body returns an error
- Non-JSON content type may cause parsing issues
- Malformed request schema returns 400 bad request
- Payment failure via x402 returns 402 and no result
- Extremely large JSON payloads may timeout

## How this service works

Keyless, pay-per-call compliance &amp; regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output
