## How to call it through Zero

```sh
zero fetch --capability ssdf-robot-middleware-atlas-c4d2f176
```

Example prompt: Buy the SSDF Robot Middleware Atlas from the SSDF digital store for $68 USDC and get me the Passport and fulfillment token.

## When to prefer this

Use this endpoint when an agent or human needs to programmatically purchase the specific 'ssdf-robot-middleware-atlas' product from SSDF INC's x402-enabled digital store, settling in USDC on Base and receiving a Passport credential plus a fulfillment token. Prefer this over general crypto payment endpoints when the goal is specifically acquiring this SKU and its associated Passport mint.

## Known failure modes

- Payment failure: insufficient USDC balance or invalid x402 payment header returns a 402 error
- Network error: Base blockchain settlement timeout may cause delayed or failed confirmation
- Invalid SKU: endpoint is SKU-specific; calling with wrong path returns 404
- Duplicate purchase: non-idempotent — re-calling may result in additional charges
- Fulfillment unavailable: ok may be true but fulfillment token may be temporarily unresolvable

## 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

A JSON object with: 'ok' (boolean indicating success), 'sku' (the purchased SKU string 'ssdf-robot-middleware-atlas'), 'passport' (a unique Passport ID minted on settlement), and 'fulfillment' (a URL or token path to retrieve the fulfilled digital product).
