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 ok: true and a receipt object containing a receiptId, status of 'paid', totalUsd amount, and an array of line items detailing the purchased goods.
Example use cases
Example prompt
“Place an order at the BasaltSurge shop 'morning-bloom-cafe' for 2 units of SKU 'COFFEE-LATTE-LG' and 1 unit of 'PASTRY-CROISNT', applying California tax jurisdiction US-CA.”
Technical details
Endpoint
POSThttps://surge-sand.basalthq.com/api/x402/orders?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to place a paid order at a BasaltSurge merchant shop using the x402 agentic payment standard on Base. Prefer this over generic payment endpoints when the merchant is hosted on BasaltHQ and you have a shopSlug and item SKUs available. Ideal for autonomous agent purchasing flows that require an on-chain receipt.
Side effects
- Invalid shopSlug returns an error — shop not found in the BasaltSurge directory
- Item SKU not recognized or out of stock for the given shop
- Payment fails due to insufficient USDC balance or x402 protocol error
- Invalid jurisdictionCode causes tax calculation failure
- Missing required fields (items or shopSlug) returns a validation error
- Network or on-chain transaction timeout causes order failure
