Key Takeaways:
Two new companies launched competing platforms on April 30, 2026, to build the payment rails for an emerging economy run by artificial intelligence agents, a foundational step that could unlock widespread autonomous commerce.
"For the past 20 years, products competed for human attention. Now they compete for agent spend," Patrick Wu, CEO and Founder of Clink, said. "Human attention is limited. Agent demand is not. The first group of merchants that can accept payments from agents will define the next generation of digital business models."
The launches from Kite and Clink represent two distinct philosophies. Kite, which raised $35 million in a round led by PayPal Ventures and General Catalyst, is building a crypto-native solution with its own Kite Chain for settlement in digital dollars. Clink, backed by Celtic and Baidu Ventures, is integrating with the existing financial system, allowing agents to pay in fiat currency using users' credit cards under strict, pre-authorized limits.
This infrastructure is emerging as major technology players like Microsoft push AI agents to become more autonomous and capable of completing tasks without human intervention. For agents to move beyond simple information retrieval and perform complex actions like booking travel or managing business logistics, they require a secure and programmable way to transact financially—a problem both Kite and Clink aim to solve.
Kite's platform combines a settlement layer, the Kite Chain, with an identity and wallet service called the Kite Agent Passport. This gives AI agents a secure wallet to hold funds and make purchases on behalf of users, who retain control over spending. The company announced pilot integrations with PayPal and Shopify and is already integrated with over 90 service providers. "Our mission is to create the trusted backbone for agent-driven economies," said Chi Zhang, Co-Founder and CEO of Kite.
Clink is focusing on what it calls "Harness Payment," enabling agents to pay for services in over 135 fiat currencies. Its first two live merchants are AI companies themselves: ModelMax, an API gateway for large language models, and PollyReach, an AI calling service. With Clink, an agent using ModelMax can now automatically top up its own API credits as they run low, preventing workflow interruptions without requiring human approval for each transaction.
