Example prompt: Buy me the SSDF recording receipt from SSDF INC's store — I want to pay $45 in USDC on Base and get my Passport minted.

## When to prefer this

Use this endpoint when you specifically want to purchase the SSDF recording receipt digital product from SSDF INC, settle the $45 payment in USDC on Base via the x402 protocol, and receive a minted Passport alongside a token-gated fulfillment link. Prefer this over generic crypto payment endpoints when the goal is acquiring an SSDF-specific digital credential or collectible.

## Known failure modes

- Insufficient USDC balance on Base — payment fails, ok: false returned
- Invalid or missing x402 payment header — 402 Payment Required response
- Network or blockchain congestion causing settlement delay
- Fulfillment token invalid or expired if accessed incorrectly
- SKU out of stock or unavailable — endpoint may return ok: false

## 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/false indicating success), sku (the purchased SKU identifier 'ssdf-recording-receipt'), passport (a minted Passport ID tied to this purchase), and fulfillment (a token-gated URL path to retrieve the purchased content or asset).
