Environment variables
BUYER_PRIVATE_KEY_FILEPath of a file whose first word is the private key of a dedicated wallet that holds only the USDC (on Arc) you are willing to spend. Without a key only the free tools appear.
BUYER_PRIVATE_KEYsecretThe same private key given directly, for a client that keeps its configuration private. A key file is safer: a key typed into a command line lands in shell history.
ARCHIPELAGO_X402_MAX_PER_CALLThe most one call may cost, in USDC (at most 1).
ARCHIPELAGO_X402_BUDGETThe most to count as paid or reserved per UTC day, in USDC, across restarts.
