Solana is doubling down on the future of machine-driven commerce. The Solana Foundation has partnered with Google Cloud to launch Pay.sh, a stablecoin-powered payment gateway designed specifically for AI agents. The tool enables autonomous software to discover, access, and pay for APIs on demand without relying on traditional billing systems such as subscriptions, API keys, or user accounts.

For the first time agents can discover, access, and pay-per-request for APIs from Google Cloud including Gemini, BigQuery, Vertex AI, and more using stablecoins on Solana.

At its core, Pay.sh introduces a new payment layer that enables AI agents to use Solana-based wallets to interact directly with cloud services. Supported APIs include major tools such as Gemini, BigQuery, and Vertex AI, as well as more than 50 community-driven providers spanning blockchain data, developer tools, and AI services. The system is optimized for microtransactions, enabling agents to pay fractions of a cent per request, an approach that aligns with the increasing need for granular, usage-based pricing in AI ecosystems.
A new model for AI commerce
Pay.sh effectively replaces static subscription models with dynamic, per-use billing. Developers can now charge for single API calls, allowing AI agents to access only what they need, exactly when they need it. This flexibility is particularly relevant as autonomous systems scale and require seamless, low-cost access to digital infrastructure.
The service operates via an API proxy hosted on Google Cloud, connecting frontend AI agents to backend services while using a Solana wallet as both an identity and payment layer. This setup eliminates friction in onboarding and billing, making it easier for machine-to-machine interactions to function independently.
Powering payments with open standards
The payment flow is built on x402, an open standard originally introduced by Coinbase and now under the Linux Foundation. By leveraging the HTTP 402 “Payment Required” status code, x402 enables real-time payments embedded directly into web requests, removing the need for separate invoicing systems.
Pay.sh also integrates the Machine Payments Protocol, developed by Stripe and Tempo, offering an additional framework for autonomous transactions.
The launch positions Solana within a fast-growing race to build stablecoin rails for AI agents. With competitors like Coinbase and MoonPay also advancing similar tools, the shift toward AI-native payments is quickly gaining momentum, reshaping how software consumes and pays for digital services.
