# x402-toolbox Open Data JSON Validator

> x402-toolbox Open Data JSON Validator is a paid API for AI agents from x402-toolbox.shablony-pro.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Validates that a given JSON payload conforms to open-data standards via a pay-per-call x402 endpoint requiring no API key.

## 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 x402-toolbox-open-data-json-validator-6249accf -d '<json body>'
```

Example prompt: Can you validate this JSON payload to make sure it's properly structured as valid open data — I want to confirm it passes the open-data JSON check before I publish it.

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call open data JSON validation with no API key or account setup — particularly suited for AI agents that handle micropayments via x402/USDC on Base and need a frictionless one-off validation call without committing to a subscription service.

## Known failure modes

- Invalid or malformed JSON input returns validation failure with ok: false
- Payment failure via x402 prevents tool invocation entirely
- Missing required 'input' field returns schema validation error
- Unsupported HTTP method (non-POST) returns 405
- Network timeout to the Cloudflare Worker returns 503

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with an 'ok' boolean indicating whether the validation passed, and a 'paid' boolean confirming the x402 micropayment was processed. May include error details if validation fails.
