## 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 ssdf-v2g-pki-protocol-41cd301f
```

Example prompt: Can you buy me the SSDF V2G PKI Protocol from the SSDF store for $64 USDC — I need the passport and fulfillment token it issues after payment.

## When to prefer this

Choose this endpoint when you specifically need to purchase the SSDF V2G PKI Protocol digital product, receive a blockchain-minted Passport upon settlement, and obtain a fulfillment token — all in a single x402-compatible payment flow settled in USDC on Base. Prefer this over generic PKI or certificate authorities when the use case involves vehicle-to-grid identity and the SSDF ecosystem specifically.

## Known failure modes

- Payment not received or insufficient USDC balance — ok returns false or request rejected
- Invalid or expired payment header — 402 Payment Required response
- Network or blockchain settlement delay — fulfillment token not immediately available
- SKU unavailable or out of stock — ok false with no fulfillment path
- Passport minting failure on Base — transaction confirmed but passport field may be empty or null

## How this service works

SSDF INC digital store. Priced in USD, settled in USDC on Base through Coinbase Business. Humans and agents buy the same SKU. Every settlement mints a Passport.

## Output

Returns a JSON object with: ok (true if purchase succeeded), sku (the product identifier 'ssdf-v2g-pki-protocol'), passport (a minted Passport identity token tied to this purchase), and fulfillment (a URL path to retrieve the delivered digital product). Payment is settled in USDC on Base via Coinbase Business and a Passport is minted on every successful settlement.
