Oobit Launches Visa-Backed Agent Cards: AI Bots Get Their Own Corporate Expense Cards

The Block·high signal

Tether-backed crypto startup Oobit launched Agent Cards — Visa-supported virtual cards that let AI agents autonomously spend USDT for subscriptions, ad spend, and cloud infrastructure. Each card is bound to a single agent with per-transaction caps, merchant category limits, and full audit trails. Supports OpenAI, Claude, AutoGen, and LangChain frameworks. Issued to a founding group of businesses with broader onboarding through June 30. A concrete infrastructure milestone for autonomous agent commerce — agents can now hold and spend money with programmable guardrails.
