## When to prefer this

Use this endpoint when you specifically need to purchase SSDF desk credits from SSDF INC, want payment settled in USDC on Base via Coinbase Business, and require a Passport NFT minted as proof of purchase. Prefer this over generic payment endpoints when the downstream workflow depends on the SSDF Passport identity artifact and the ssdf-desk-credits SKU.

## Known failure modes

- Insufficient USDC balance on Base causes payment failure and a non-ok response
- Network or blockchain congestion delays settlement and passport minting
- Invalid or expired x402 payment header results in 402 Payment Required error
- Fulfillment token unavailable if minting pipeline encounters an error
