Solana rolls out Pay.sh with Google Cloud to bring pay-per-use API payments to AI

The Solana Foundation has introduced Pay.sh, a new payment gateway built in collaboration with Google Cloud, aimed at enabling autonomous AI agents to access and pay for APIs using stablecoins on the Solana network.

The launch targets a growing friction point in the AI economy: while agents increasingly automate workflows, access to enterprise-grade APIs still requires manual onboarding, credentials, and billing relationships.

Pay.sh attempts to remove those barriers.

What is Pay.sh?

Pay.sh is a gateway that allows AI agents to discover APIs in one place, access them without creating accounts and pay per request using stablecoins.

Instead of traditional authentication systems, the model replaces credentials with payments, effectively making each transaction its own authorization.

How it works

The system is designed to let AI agents not just access services, but also handle payments seamlessly within the same workflow, removing the need for separate billing or authentication steps:

• Users connect a Solana wallet to AI interfaces such as Gemini or Claude
• Funds can be added via credit card or stablecoins
• Agents can then browse APIs, view pricing in real time, and execute calls instantly

Under the hood, Pay.sh operates as an API proxy layer on Google Cloud infrastructure.

• It routes requests to services like Gemini, BigQuery, and Cloud Run
• Payments are processed via Solana and settled within seconds
• The protocol enforces enterprise-grade controls such as rate limits and access permissions

In essence, the wallet becomes both identity and payment mechanism.

What APIs are available?

The platform aggregates both first-party and third-party APIs into a single access layer:

Google Cloud integrations

• Gemini (AI inference)
• BigQuery and BigTable (data infrastructure)
• Vertex AI (model access)
• Cloud Run

Community APIs (50+ providers)

These span multiple categories:

• E-commerce: tools for autonomous buying, selling, and fulfillment
• Data and intelligence: platforms like Dune Analytics and Nansen for market insights
• Communications: APIs enabling email, SMS, and voice-based actions
• Blockchain infrastructure: services such as Helius, Alchemy, and The Graph

Most API services today already offer usage-based pricing, but still require accounts, API keys and billing setup, including platforms run by companies like OpenAI and Anthropic.

Pay.sh is trying to remove that layer altogether by letting payments handle access, making the process simpler for automated systems.

Pay.sh is built on machine-native payment protocols — x402 and MPP (Machine Payment Protocol) — designed specifically for direct, automated transactions between software systems. Unlike proprietary billing infrastructure, these are open standards, meaning any developer or service provider can build compatible systems without being locked into a single platform's ecosystem.

That openness is what could make Pay.sh a true industry standard rather than just another walled garden.

These open standards allow developers and service providers to create interoperable systems without relying on closed billing infrastructure or traditional account-based models.

Why this matters

The launch points to a broader shift toward what is often described as “agentic commerce,” where software, rather than humans, becomes the primary user of digital services.

By reducing friction around payments and access, the model allows developers to automate workflows more easily, enables API providers to monetize usage without managing billing systems, and gives AI agents the ability to operate across multiple services on their own.

It also reflects a gradual move away from subscription-based software toward more granular, usage-based pricing.

The bigger picture

Pay.sh positions Solana Foundation at the intersection of AI infrastructure and blockchain payments, a space increasingly dominated by experiments in autonomous systems and machine-driven economies.

With backing from Google Cloud and integration across both enterprise and crypto-native services, the platform aims to establish a new standard: APIs that can be accessed and paid for programmatically, without human intervention.

Whether that vision scales will depend on adoption but the direction is clear: software is no longer just using APIs. It’s starting to pay for them too.
