The Solana Foundation has introduced Pay.sh, a new payment gateway built in partnership with Google Cloud, aimed at enabling autonomous AI agents to access and pay for APIs using stablecoins on the Solana network.
The launch addresses a growing bottleneck in the AI economy: while agents increasingly automate workflows, access to enterprise-level APIs still requires manual onboarding, credentials, and billing relationships.
Pay.sh tries to remove these 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 login credentials with payments, effectively turning each transaction into its own authorization.
How it works
The system is designed to allow AI agents to not only access services, but also process payments seamlessly within the same workflow, eliminating the need for separate billing or authentication steps:
- Users connect a Solana wallet to AI interfaces such as Gemini or Claude
- Money can be added via credit card or stablecoins
- Agents can then browse APIs, view pricing in real time, and make calls instantly
Under the hood, Pay.sh functions as an API proxy layer on the Google Cloud infrastructure.
- It forwards requests to services such as Gemini, BigQuery, and Cloud Run
- Payments are processed via Solana and settled within seconds
- The protocol enforces enterprise-level controls such as speed limits and access permissions
Essentially, the wallet becomes both an identity and a payment mechanism.

What APIs are available?
The platform collects both first 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 include several categories:
- Ecommerce: tools for autonomous buying, selling and fulfillment
- Data and intelligence: platforms such as Dune Analytics and Nansen for market insights
- Communication: APIs that enable 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 settings, including platforms operated by companies like OpenAI and Anthropic.
Pay.sh aims to remove that layer altogether by letting payments control access, simplifying the process for automated systems.
Pay.sh is built on machine-native payment protocols – x402 and MPP (Machine Payment Protocol) – which are specifically designed for instant, 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 ecosystem.
That openness is what could make Pay.sh a true industry standard rather than just a 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 signals a broader shift towards what is often described as ‘agentic commerce’, where software, rather than people, becomes the main user of digital services.
By reducing friction around payments and access, the model enables developers to more easily automate workflows, allows API providers to monetize usage without managing billing systems, and gives AI agents the ability to work independently across multiple services.
It also reflects a gradual shift from subscription-based software to 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 the support of Google Cloud and integration between both enterprise and crypto-native services, the platform aims to establish a new standard: APIs that are programmatically accessible and affordable, without human intervention.
Whether that vision scales will depend on adoption, but the direction is clear: software no longer only uses APIs. It’s starting to pay for them too.
