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.
