How this service works
Basaltsurge is a full‑stack crypto commerce platform: multi‑currency payments (USDC, ETH, cbBTC) on Base, the x402 agentic payment standard, Google's Universal Commerce Protocol (UCP), instant receipts & QR terminals, on‑chain split releases, shops, loyalty, and whitelabel partner containers.
Output
Returns a JSON object with a boolean ok status, the plan name (e.g. 'pro'), the newly provisioned apiKey, a human-readable message, the price in USD, and a unique subscriptionId for the created subscription.
Example use cases
Automate crypto payment onboarding
“I need to set up a BasaltSurge subscription for my team so we can start accepting USDC and ETH payments right away. Just grab us the pro plan and give me the API key.”
Enable x402 agentic commerce workflows
“Set up a BasaltSurge enterprise subscription for our agent fleet using x402 payment—we need the API keys provisioned so our agents can transact on-chain without manual approval.”
Integrate multi-currency Base payments
“Get me a BasaltSurge plan that supports all the features—USDC, ETH, cbBTC on Base—and issue an API key so I can integrate instant crypto receipts and QR terminals into our platform.”
Technical details
Endpoint
POSThttps://surge-sand.basalthq.com/api/x402/subscribeWhen to prefer
Use this endpoint when an AI agent or application needs to programmatically subscribe to the BasaltSurge crypto commerce platform and obtain an API key, especially in automated or agentic workflows using the x402 payment standard. Prefer this over manual sign-up when building agent-driven onboarding pipelines or when the x402 payment protocol is already in use.
