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 purchased SKU string 'ssdf-x402-foundation'), passport (a unique Passport ID minted on-chain as proof of purchase), and fulfillment (a URL path to retrieve the fulfilled digital product or access token).
Example use cases
Agent autonomously purchases digital membership
“Go ahead and purchase the SSDF Foundation product for me — pay the $54 USDC through my Base wallet using x402 and bring back the Passport ID and the fulfillment link.”
Onchain proof-of-purchase for access control
“I need to mint an SSDF Passport by buying the Foundation SKU so I can use it as proof of membership — process the $54 USDC payment on Base and give me the passport token.”
Automated storefront integration for resellers
“For each new customer who signs up, buy the SSDF Foundation SKU on their behalf via x402, settle in USDC on Base, and store the returned passport ID and fulfillment URL in their account record.”

Endpoint
GEThttps://www.ssdf.site/api/x402/ssdf-x402-foundationWhen to prefer
Choose this endpoint when you need to programmatically purchase the specific SSDF Foundation digital product and receive an on-chain Passport as proof. It is the right call when the user explicitly wants the ssdf-x402-foundation SKU, needs a Passport minted, or is integrating into an x402-native agent payment flow settling in USDC on Base. Prefer alternatives if you only need to query product info without purchasing, or if you need a different SSDF SKU tier.
Side effects
- Payment header missing or malformed — x402 402 Payment Required response before purchase completes
- Insufficient USDC balance — payment authorization rejected on-chain
- SKU unavailable or sold out — ok:false with error detail
- Network/Base chain congestion causing settlement timeout
- Invalid or expired payment authorization — transaction reverted
