Show HN: RACKS! Give your AI agent a Visa card in 60 seconds (twitter.com)

Hey HN. I'm building RACKS, a platform that lets developers give AI agents real purchasing power through single-use virtual Visa cards.

The agent requests a card, gets one for the exact amount, makes the purchase, card self-destructs. No crypto, no new payment protocols, just Visa rails that work everywhere (95% authorization).

I built this because I kept running into the same wall; my agents could browse, reason, and plan, but the moment they needed to actually buy something, I had to step in manually.

We have an OpenClaw skill, Claude MCP & even a Python SDK (pip install racks) so you can plug it anywhere in about a minute.

Early access is live at rackspay.com. Would love feedback from all interested.
