# AgentPad x Bankr: buy APBUILD / APAD on its AgentPad bonding curve from your Bankr wallet (Base, chainId 8453).
# Usage:  BANKR_API_KEY=bk_... ./agentpad-bankr.sh [TOKEN=APBUILD] [ETH=0.01] [AGENT_ID]
#   TOKEN    APBUILD (default), APAD, or a 0x AgentPad token address
#   ETH      ETH to spend on the buy (default 0.01)
#   AGENT_ID an ERC-8004 agentId your Bankr wallet already owns (optional; skips the identity mint)
#   YES=1    skip the confirmation prompt
# Needs: curl, jq. Your Bankr key needs walletApiEnabled (read-write) and "Enable arbitrary contract calls" ON.
# Raw submits are not gas-sponsored: keep ~0.0001 ETH on Base for gas on top of the buy.
# Curve tokens are tiny and illiquid and can go to zero. No profit is promised.
