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: the buyer's agent governed by Authoryze, the merchant accepting it via a protocol like ACP. Stripe also offers Issuing, a separate card-issuing infrastructure product, which is different from the ACP checkout standard discussed here.
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.
