## How to call it through Zero

```sh
zero fetch --capability ssdf-mcp-pack-purchase-ba7864d7
```

Example prompt: Buy me the SSDF MCP Pack from the SSDF digital store — pay $79 in USDC on Base and get me the fulfillment link and my Passport ID.

## When to prefer this

Use this endpoint when an agent or human needs to purchase the specific SSDF MCP Pack digital product, paying $79 USDC on Base via the x402 payment protocol. It is the canonical purchase endpoint for this SKU and simultaneously mints a Passport as proof-of-purchase, making it the right choice when downstream access requires both a fulfillment token and a verifiable Passport ID. Not suitable for free downloads, subscriptions, or products from other stores.

## Known failure modes

- Payment insufficient or failed — USDC balance too low or x402 payment not accepted, ok=false returned
- Invalid or expired payment header — x402 protocol mismatch, likely 402 Payment Required response
- Network/chain error on Base — settlement may not confirm, fulfillment not issued
- SKU unavailable — product out of stock or temporarily delisted
- Passport minting failure — on-chain mint fails even if payment succeeded, leaving fulfillment incomplete

## 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, e.g. 'ssdf-mcp-pack'), passport (a minted Passport ID tied to the purchase), and fulfillment (a token-gated URL path to redeem or download the product).
