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 (boolean success flag), sku (the product identifier 'ssdf-ros2-protocol'), passport (a unique Passport ID minted on-chain upon purchase), and fulfillment (a URL path to retrieve the actual protocol content once payment is confirmed).
Example use cases
Robotics developer buying ROS2 protocol
“Purchase the SSDF ROS2 Protocol for me — I need the Passport and the fulfillment link so I can access the protocol content. Pay the $58 USDC from my Base wallet.”
Agent autonomously acquiring protocol access
“Go ahead and buy the ssdf-ros2-protocol SKU from SSDF's store, settle the $58 in USDC on Base, and bring back my Passport ID and where to download the content.”
Team lead purchasing for developer onboarding
“Order the SSDF ROS2 Protocol digital product right now — we need the Passport minted and the fulfillment URL so our new engineers can get started.”
Technical details
Endpoint
GEThttps://www.ssdf.site/api/x402/ssdf-ros2-protocolWhen to prefer
Use this endpoint when you need to programmatically purchase the SSDF ROS2 Protocol digital product, receive an on-chain Passport as proof of purchase, and obtain a fulfillment URL to access the content — all via a single $58 USDC payment over the x402 protocol on Base. Prefer this over manual checkout flows when an AI agent needs to autonomously acquire robotics protocol access without human interaction.
Side effects
- Insufficient USDC balance — payment of $58 cannot be completed
- x402 payment protocol failure — Base network congestion or wallet misconfiguration
- Invalid or expired payment header — agent must re-initiate the x402 flow
- Fulfillment token generation failure — ok: false returned with no passport or fulfillment URL
- Network timeout on Base settlement — transaction may be pending
