Stripe

Accept AI-agent payments via Stripe Checkout. The adapter returns a hosted checkout URL the agent hands to the customer, or confirms payment directly using a Stripe payment method ID — no marketplace required.

Live Validated v1.0.0 Since April 2026

About this integration

Stripe is the most widely deployed payment infrastructure in e-commerce. This ACP adapter connects your Stripe account to the Agentic Commerce Protocol, giving AI agents two ways to complete a purchase: a hosted checkout URL the agent hands to the customer, or a direct payment method confirmation using a Stripe pm_xxx ID the agent already holds. Both flows are deployed and live on cinematiccard.com and tradeexecutor.ai.

What this enables

  • Accept AI-agent payments via hosted Stripe Checkout
  • Return one-time checkout URLs agents can hand to customers
  • Confirm payments directly using a Stripe payment method ID — no redirect
  • Handle webhook-confirmed fulfilment automatically
  • Support promo codes and discount logic through Stripe promotions

Capabilities

This adapter exposes the following ACP endpoints, callable by any compatible AI agent.

Prerequisites

Requires an active Stripe account with a live secret key. You will need your Stripe Secret Key (sk_live_...) and a Webhook Signing Secret (whsec_...) configured to receive payment_intent.succeeded events from your ACP server URL.

FAQ

Does this work in Stripe test mode?
Yes — use your test secret key (sk_test_...) during the install test. The ACP substrate switches to live mode once you provide sk_live_... credentials.
Which Stripe events does the webhook listen for?
The adapter handles payment_intent.succeeded, payment_intent.payment_failed, and checkout.session.completed. Only events from your own account are processed.
Can agents use saved payment methods?
Yes. If the agent holds a Stripe pm_xxx from a prior interaction, the payment_method.confirm flow completes the charge without presenting a checkout URL to the customer.
Is SCA / 3D Secure supported?
Yes. Stripe handles SCA automatically on hosted checkout. For the payment_method flow, the server confirms with automatic_payment_methods enabled.
