Authoryze and Stripe operate at different layers of agentic commerce, so this is less a head-to-head and more a question of which problem you are solving. Stripe's Agentic Commerce Protocol (ACP), built with OpenAI, is a merchant-side standard. It lets businesses accept purchases from AI agents and complete checkout on ACP-enabled sites using shared payment tokens. Authoryze is on the buyer side. It governs how a user's agent spends, issuing a single-use virtual card per approved purchase with spending rules, human approval, and audit, connected over MCP.
Different Layers
| Layer | Authoryze | Stripe ACP |
|---|---|---|
| Side of the transaction | Buyer side: controlling how an agent spends | Merchant side: accepting agent purchases at checkout |
| What it provides | Single-use cards, spend rules, human approval, audit | A checkout/payment standard for merchants and platforms |
| Integration | MCP-native, connect your agent | Merchant/platform integration of the protocol |
| Spend governance | Per-agent and cross-agent limits, approval thresholds, duplicate detection | Not the focus; ACP standardizes the checkout exchange |
How They Relate
These are complementary more than competing. Stripe's ACP is about merchants being able to sell to agents and complete checkout. Authoryze is about a person or business being able to let their agent buy things safely, with control over how much it spends, where, and with human approval when needed. A purchase could in principle involve both, with the buyer's agent governed by Authoryze and the merchant accepting it via a protocol like ACP. ACP is what powers checkout inside ChatGPT and Microsoft Copilot, and Stripe now packages it for sellers as the Agentic Commerce Suite, which also supports Google's Universal Commerce Protocol. Stripe has buyer-side agent products too. Link's wallet for agents gives a consumer's agent a one-time card with per-purchase approval, and Issuing for agents lets a business issue its own agent cards. We cover the first in Authoryze vs Stripe Link for agents.
When Authoryze Is the Right Choice
Choose Authoryze when your need is buyer-side control. You are running an agent and want to govern its spending with single-use cards, per-agent and cross-agent limits, human approval, and audit, connected over MCP, regardless of which checkout standards merchants support.
