Introducing Reinx: The Financial Command Center for AI Agents
A new kind of financial platform
Today we are opening the private beta of Reinx, a platform that gives every AI agent its own virtual card and crypto wallet with human-controlled spending limits, real-time approve/deny authority, and complete transaction visibility.
If you are building with AI agents — whether that means coding assistants, autonomous ad managers, inventory bots, or anything that needs to spend money on your behalf — Reinx is the infrastructure layer that was missing. Instead of sharing your personal card across every agent and hoping for the best, you create dedicated agent accounts with independent budgets and rules enforced at the payment network level.
What you get in the beta
The private beta includes the full core platform. Each agent account comes with a Stripe-issued virtual card for traditional commerce and Privy-powered wallets on Base and Solana for agent-to-agent micropayments. You set a single unified budget per agent, and the platform dynamically routes funds to card or wallet depending on the transaction type. No manual balance splitting.
Spending controls are granular and immediate. Set per-transaction limits, daily velocity caps, merchant category restrictions, and approval thresholds. Transactions within your rules auto-approve in milliseconds. Transactions above your threshold trigger a push notification so you can approve or deny with context — the agent name, amount, merchant, and the reason the agent wants to make the purchase.
Everything connects through our MCP server, which means any agent framework that supports the Model Context Protocol can integrate in minutes. Your agents get 16 financial tools out of the box: balance checks, payment requests, spending rule queries, denial feedback retrieval, and more. Every tool call is logged with full metadata, building the behavioral dataset that will power agent health scores in a future release.
Who this is for
The beta is for developers and AI agent builders who are already running agents that spend money. If you are building on LangChain, CrewAI, AutoGen, or using coding agents like Cursor and Claude Code, and you have felt the pain of managing agent finances with shared cards and manual tracking, Reinx is built for you.
We are starting with a small group of beta users to ensure the platform is solid before opening more broadly. If you are interested, visit reinx.ai to request access. There is no waitlist gating — we are onboarding users as quickly as we can verify accounts through Stripe's KYC process. Free tier includes unlimited agents, cards, and wallets with full spending controls. No credit card required to start.
