Values you fill in

BUYER_PRIVATE_KEY_FILE env
Path 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_KEY secret env
The 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_CALL env
The most one call may cost, in USDC (at most 1).
ARCHIPELAGO_X402_BUDGET env
The most to count as paid or reserved per UTC day, in USDC, across restarts.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
