get_order_status
Check the status of an existing order. Returns status (pending, confirmed, rejected, expired), payment info, and items.
get_x402_payment_details
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.
set_budget
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.
get_budget_status
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.
