Stripe has launched a new Software Development Kit (SDK) designed for AI agents, allowing large language models (LLMs) to interact with various APIs, including payment, billing, and issuing services. The SDK integrates with platforms such as Vercel, LangChainAI, and CrewAI, enabling developers to utilize any model through functions that charge on a per-token basis. This development is seen as a significant advancement in the capabilities of AI agents, which can now process transactions and respond to customer requests in multiple languages. The pricing model based on token usage is considered a critical step in addressing how to effectively charge for these AI services. The launch follows a trend of recent solutions aimed at creating AI agents, with Stripe positioning itself prominently in this emerging field.
