## 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-vin-validator-eaac9ab6
```

Example prompt: Can you check if this VIN is valid: 1HGBH41JXMN109186?

## When to prefer this

Choose this endpoint when you need a lightweight, no-signup, pay-per-call VIN validation without committing to a subscription API key. Ideal for agents that only occasionally need to verify VINs, or for pipelines where identity management overhead is unwanted and micropayment-based access fits the architecture.

## Known failure modes

- Invalid or malformed VIN string returns ok: false
- Missing VIN input causes request failure
- Payment not processed results in 402 response before validation occurs
- Non-standard VIN formats (non-17 character) may return validation failure
- Network timeout on Cloudflare Worker edge

## 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 request succeeded and a 'paid' boolean confirming the x402 micropayment was processed. The core validation result indicates whether the provided VIN passes structural and checksum validation rules.
