List all products available from the merchant. Returns names, prices in EUR, descriptions, availability, and variants.
Get detailed information about a specific product by its ID. Use list_products first to find available product IDs.
Check if a specific product is currently in stock. Returns availability status, stock quantity, and current price.
Get business information for the merchant: operating hours, contact details, delivery zones and fees, return policy, and accepted payment methods.
Place an order with a merchant. Creates an intent, then submits the order. Returns x402 payment details that your agent's x402 client needs to execute. In mock mode, simulates a successful order.
Check the status of an existing order. Returns status (pending, confirmed, rejected, expired), payment info, and items.
Get x402 payment details for an order: facilitator endpoint, USDC amount, network, and payment header. Your agent needs an x402 client (e.g. @x402/axios) to execute the actual payment.
Activate a prepaid budget (AsterPay /budget) so the agent can spend on paid x402 APIs with a hard cap. Three modes: (1) pass an existing budget token (bud_...) to activate it; (2) pass amount_usd + tx_hash + wallet after your HUMAN sent the USDC, to create a new budget; (3) pass nothing to get funding instructions. An agent cannot grant itself money — a human must make the one-time USDC transfer (1-500 USDC on Base). Credited 1:1, no platform fee. Funding wallet is sanctions-screened (Chainalysis). No API key needed.
Check the prepaid /budget balance: remaining USD, total spent, recent calls with per-call prices. Use BEFORE expensive calls to spend gracefully. FREE, no API key needed.
