X Pay has announced private-round backing from Zerra Ventures, Skyland Ventures, BigBull Capital and Credit Scend as it continues developing programmable payment infrastructure for AI agents, APIs, SaaS applications and onchain services.

The announcement brings together a group of strategic investors around X Pay’s vision for internet-native payments: enabling software and digital services to interact with payment systems directly, with payment flows integrated into the applications themselves.

At the heart of that vision is X Pay’s work on x402 payment infrastructure, designed around HTTP-based payment flows. The company is building toward an environment where payments can become a programmable part of a digital interaction, rather than a separate checkout experience.

Private-Round Backing for X Pay’s Next Chapter

The participation of Zerra Ventures, Skyland Ventures, BigBull Capital and Credit Scend marks a new milestone for X Pay as it continues building its technology, ecosystem and developer infrastructure.

The company’s focus spans AI-driven applications, API access, software services and onchain interactions. These areas share a common requirement: a way for applications to request and process payments as part of an automated workflow.

The private-round announcement highlights X Pay’s ambition to serve that requirement through infrastructure that connects stablecoin payments, blockchain systems and developer-facing tools.

Building Payments into Digital Interactions

X Pay is working toward payment flows in which an application or AI agent can interact with a paid service directly. Its approach aims to make payments an integrated part of software activity, supporting use cases such as access to an API, an AI service or an onchain application.

For developers, the intended benefit is a closer connection between the service being provided and the payment that enables access to it. Instead of designing every interaction around a manual checkout, developers could build applications where payment steps form part of the underlying workflow.

These examples describe the infrastructure X Pay is developing and its intended use cases.

A Payment Layer for AI Agents, APIs and SaaS

X Pay’s vision brings several digital-service categories into a common payment framework:

• AI agents: payment interactions designed to fit software-driven tasks and automated service access.

• APIs: payment flows connected to the use of digital interfaces and services.

• SaaS applications: programmable payments integrated into software experiences.

• Onchain services: applications that connect blockchain-based settlement with digital activity.

By combining these areas, X Pay aims to make payments a more natural part of how applications communicate and exchange value.

Building the Payment Layer for the Next Internet

As more digital interactions are initiated by software, X Pay sees an opportunity to develop payments that can be initiated, verified and settled programmatically. Its work brings stablecoins, APIs, AI agents and blockchain infrastructure into a unified vision for internet-native commerce.

With its newly announced private-round backers, X Pay continues working toward that vision under its message: “Payments for a smarter world.”
