SAN FRANCISCO AND DUBLIN-Stripe, the programmable financial services company, today announced that OpenRouter, a platform that gives over 5 million developers access to hundreds of AI models through a single interface, is building on Stripe to support its revenue growth, global expansion, and fraud protection.

OpenRouter lets developers and enterprises easily use a wide range of AI models to build, scale, and optimize AI applications without integrating separately with each underlying model provider. To support this experience, OpenRouter uses Stripe Invoicing to bill customers on flexible terms and collect payments, while Stripe Tax automates global tax calculation and collection. OpenRouter also uses Radar for Fraud Teams to fine tune fraud controls and manage risk performance from the Stripe dashboard.

OpenRouter uses Stripe to accept payments from its global customer base across credit cards and local payment methods, including Alipay, WeChat Pay, Amazon Pay, Cash App, and Google Pay. Stripe's Adaptive Pricing allows OpenRouter to display prices in local currencies at checkout across more than 150 countries, providing a localized payment experience for its customers.

"Stripe handles payment complexity in an elegant way so we can focus on making AI models accessible and high-quality for developers everywhere. As OpenRouter scales globally, having reliable payments infrastructure is essential to delivering the seamless experience our users expect," said Alex Atallah, cofounder and CEO of OpenRouter.

AI products face constantly changing inference costs as model providers update pricing across different models. If developers do not adjust prices when costs fall, they risk losing competitiveness. If costs rise and pricing does not keep up, margins suffer. To manage this, developers typically need to spend considerable time and effort manually tracking cost changes and updating pricing. To solve this, Stripe partnered with OpenRouter so developers can route model requests through OpenRouter while Stripe automatically tracks usage, applies pricing, and handles billing. Together, Stripe and OpenRouter enable developers to respond to cost changes automatically and scale monetization without operational complexity.

Stripe is building the economic infrastructure for AI. That includes partnering with the most ambitious AI companies and being their growth partner by providing the most reliable and fastest-improving financial infrastructure. Every company in the Forbes AI 50 that monetizes does so on Stripe.
