Example Prompts for Claude

Once connected, you can ask Claude to generate payment links:

"Can you create a payment link for $10 USD donations to my project?"
"Generate a Coinbase Commerce payment link for my coffee shop with a price of $5.50"
"Look up the payment status for charge ID 93e23c3e-8220-4e6c-9bc3-ea3548339621"

Claude will use the appropriate tools to fulfill these requests, generating payment links you can share with customers.
