Link
Link is a digital wallet developed by Stripe that is designed to streamline online checkout by allowing users to securely store and reuse their payment information across multiple websites. It enables customers to save credit or debit cards, billing details, and shipping addresses in a single account, which can then be automatically filled in during purchases wherever Link is supported, eliminating the need to repeatedly enter payment data. Its core purpose is to create a faster, frictionless checkout experience that improves convenience while maintaining secure transaction handling. Link supports multiple payment methods beyond traditional cards, including bank payments, buy-now-pay-later options, and certain international payment systems, depending on availability. It also provides account-level features such as subscription management, allowing users to view active subscriptions, update payment methods, and track recurring charges in one place.

Preloop
Preloop is the open source AI agent control plane for agents that take real actions. It combines an MCP firewall for tool access, an AI model gateway for cost, safety, and attribution, policy-as-code with human approvals, runtime session observability, and audit trails in a single self-hostable platform. AI agents can deploy code, change infrastructure, move money, touch production data, and burn model spend in seconds, so Preloop helps teams control what agents can do, how much they spend, and which actions require human approval. It works with OpenClaw, Hermes, Claude Code, Codex CLI, Cursor, Gemini CLI, Windsurf, Cline, OpenCode, and any MCP-compatible agent or managed runtime. Access rules can inspect arguments and context, not just tool names, with CEL expressions for fine-grained conditions. Teams can start with observability, then layer in approvals and deny rules without SDKs or invasive app changes.

Visa CLI
Visa CLI is a command-line interface developed by Visa Crypto Labs that enables AI agents and automated workflows to execute secure card payments directly from the terminal, introducing a new model of “command line commerce.” It allows developers to integrate payments into coding environments without relying on traditional API keys or pre-funded accounts, reducing setup complexity and minimizing security risks associated with credential management. Instead of navigating graphical interfaces, users and AI agents interact through text-based commands, which are inherently more compatible with machine-driven processes and automation. Visa CLI supports programmatic payments, allowing agents to pay for services such as APIs, datasets, or digital resources on demand as part of real-time workflows. It uses secure authentication methods like tokenization and certificate-based access, helping ensure that transactions remain protected while simplifying implementation.
