Introduction
Axiom is payment infrastructure for AI agents — enabling them to make real-world purchases on behalf of users.
Axiom is a payment platform that bridges AI agents and real-world commerce. It provides a secure wallet system where users fund their accounts, define spending rules, and authorize AI agents to make purchases using single-use virtual debit cards.
Why Axiom?
AI agents are increasingly capable of performing complex tasks — booking travel, ordering supplies, managing subscriptions. But they lack a secure, controlled way to spend money. Axiom solves this by giving agents access to payment capabilities through the Model Context Protocol (MCP), while keeping users in full control.
Key Concepts
- Wallet — Each user has a funded wallet. Agents draw from this balance when making purchases.
- Single-Use Cards — Every purchase gets a unique virtual card with a spend limit. The card is automatically closed after the first transaction.
- Rules — Users define AI-driven spending rules that control when agents can spend, how much, and on what categories.
- MCP Integration — Agents connect to Axiom via the Model Context Protocol with scoped OAuth2 permissions.
