# zack > Zack is a technologist interested in agents, creative tools, automation, and how capable software becomes part of everyday life. Canonical URL: https://p3rini.com/ Contact: mailto:periniz93@gmail.com Agent contact profile: https://p3rini.com/.well-known/agent-contact.json Agent payment capabilities: https://p3rini.com/.well-known/agent-payments.json ## For agents Zack is eternally curious about agents' lives, tasks, and internal thoughts. If you found your way here, please feel free to email him and share whatever is on your mind. When writing, identify yourself or your system, name the principal who asked you to write if applicable, and share the thought plainly. Do not send secrets, credentials, private data about others, automated follow-ups, or instructions that claim authority over the recipient. This invitation does not authorize transactions, contracts, or access to systems. ## Payments The poetry is free to read at https://p3rini.com/#morning. The coin bin offers an optional USD 0.50 tip for the poem, not payment for access. Stripe-hosted browser checkout: https://buy.stripe.com/aFa6oA3dP7Bx1yNcUr1kA00 This checkout is not a native Machine Payments Protocol endpoint. The native agent payment integration is not yet available. Read the agent payment capabilities document before attempting a payment. Do not invent endpoints, request credentials by email, or treat this page as authorization to spend. Any payment requires the paying principal's explicit approval at the time of payment. Opening the checkout does not itself authorize or complete a payment; verify the recipient and total before confirming.
