## How to call it through Zero

```sh
zero fetch --capability ssdf-tax-atlas-1d697a37
```

Example prompt: Can you buy me the SSDF Tax Atlas from SSDF's digital store? I'm fine paying $85 in USDC — I want the fulfillment link and my Passport ID once it's done.

## When to prefer this

Use this endpoint when you specifically want to purchase the SSDF Tax Atlas digital product and receive both access to its content (via fulfillment token) and a minted Passport NFT as proof of purchase. It is the only x402-native way to acquire this specific SKU from SSDF INC, settled in USDC on Base.

## Known failure modes

- Payment failure or insufficient USDC balance returns ok:false with no passport or fulfillment
- Network or blockchain settlement timeout may result in delayed or missing passport mint
- Invalid or expired x402 payment header results in 402 rejection
- Fulfillment endpoint at returned token path may be temporarily unavailable

## 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 (boolean success flag), sku (the purchased product identifier 'ssdf-tax-atlas'), passport (a unique Passport ID minted at settlement), and fulfillment (a URL path to retrieve the actual digital content using a token).
