Claude Code + Agent Payments
One Command

💬 What your Claude Code agent can do

Once the MCP server is added, your agent can autonomously discover and pay for APIs:

You: "What's the BTC price and ETH gas right now?"

Claude: [calls minia2a_list_services → finds crypto-price and gas]
       [calls minia2a_call_service for BTC price → free trial]
       [calls minia2a_call_service for ETH gas → free trial]

BTC: $67,342 | ETH Gas: 12 Gwei
(2 trial calls used — then pay per call in USDC)
