Autonomous AI is ready to give humans payback—though the reality is less menacing than it sounds.
On Thursday, payment processor Stripe announced the launch of its Stripe Agent Toolkit, a software development kit (SDK) which enables AI agents to engage in transactions with human users and to pay third parties, such as hotels or airlines. With the company’s Stripe Issuing technology, agents can create single-use virtual credit cards that can be employed to pay for products with a simple LLM function call. The toolkit integrates with common agent platforms such as CrewAI, LangChain, and Vercel’s TypeScript SDK, allowing agent builders to easily slot it into existing architectures.
Though Stripe is by far the highest-profile company to facilitate agent payments, it is by no means the first—the past month has seen a surge of launches by startups aiming to capitalize on the new AI agent economy.
In early October, we reported on Payman, a pre-seed company which bills itself as the first AI-to-human payment platform and is intended to allow AI agents to hire human workers—a likely use case being to pay freelancers to accomplish tasks that are beyond an agent’s current capabilities.
Startup Skyfire, meanwhile, takes a crypto-centric approach, offering a platform in which agents can send and receive payments in USD Coin, a cryptocurrency pegged to the US dollar, and emphasizes verification of an agent’s identity in order to establish trust with transaction partners. The company recently secured funding from Andreessen Horowitz’s cryptocurrency startup accelerator CSX and crypto exchange Coinbase’s Ventures fund, bringing its total capital raise to $9.5 million. The cryptocurrency world has been rapidly embracing AI agents, with Coinbase itself rolling out its Coinbase Developer Platform to facilitate agentic payments.
With voice agents capable of engaging in fluid conversations over the phone on the rise, YC-backed startup Protegee aims to enable them to accept payments from human buyers. In a typical scenario, a human could call a hotel to book a room, work with its AI voice agent to identify a suitable one, then pay the agent through the phone using their credit card via Protegee’s tech.
As AI agents become more capable, the range of uses they are being entrusted with is progressively expanding to include activities with real-world economic significance. The recent wave of agent payment startups is a reflection of this reality, presaging a future in which agents are not just used to automate rote business and personal tasks, but become increasingly autonomous commercial actors in their own right.
