- Pay.sh lets AI agents access APIs using Solana wallets, removing need for accounts, keys, or subscriptions.
- Gateway enables instant stablecoin payments for pay-per-call API usage across Google Cloud and partners.
- Open protocols and integrations expand access to AI, data, and blockchain APIs within a unified marketplace.
The Solana Foundation, in collaboration with Google Cloud, introduced Pay.sh, a payment gateway for AI agents to access APIs without accounts or subscriptions. The system enables pay-per-call usage through Solana wallets using stablecoins. The launch targets friction in API access, where agents previously required human-managed credentials and billing setups.
How Pay.sh Connects Agents To APIs
According to the Solana Foundation, Pay.sh allows agents to discover and pay for APIs directly from a unified marketplace. Agents link a Solana wallet to interfaces like Gemini, Claude Code, Codex, Openclaw, and Hermes. They can then fund wallets quickly and begin accessing services without creating accounts.
Notably, the gateway operates as an API proxy built on Google Cloud infrastructure. It sits in front of services like Gemini, BigQuery, Cloud Run, and Vertex AI. When an agent initiates payment using x402, the system verifies the request and enforces controls.
Meanwhile, the wallet acts as the agent’s identity, removing the need for API keys or credential management. Payments settle in seconds using stablecoins on Solana. Providers then receive reconciled payments without manual billing processes.
Access Expands Across Google And Third-Party APIs
Through Pay.sh, agents can access official Google Cloud APIs and over 50 third-party endpoints. These include tools for AI inference, data warehousing, and blockchain infrastructure.
For example, agents can interact with services like Gemini, BigQuery, and Vertex AI. Additionally, integrations extend to Cloud Run and other enterprise services.
The marketplace also includes community APIs across e-commerce, communications, and data intelligence. Providers such as Rye, BigCommerce, Exa, Dune Analytics, and Nansen support these categories.
Open Standards And Ecosystem Support
Pay.sh runs on open protocols including x402 and MPP, designed for machine-native payments. According to the Solana Foundation, these standards allow developers to build and extend integrations freely.
Moreover, the system supports private datasets within Google Cloud. Enterprises can expose data through APIs while facilitators handle payments securely. This setup keeps data access controlled without direct account creation.
The platform also integrates with ecosystem partners like PayAI, Crossmint, Merit Systems, and Moonpay. These contributors expand the API catalog and support broader agent access.
