Solana Foundation and Google Cloud launched Pay.sh payment gateway for AI agents

The Solana Foundation and Google Cloud AI have launched Pay.sh, a new payment gateway that allows agents to access and pay through APIs on Solana using stablecoins.

The gateway is designed to eliminate the manual steps that still define much of the software economy, including account creation, credential management, KYC, billing communications and subscriptions. Pay.sh allows agents to access APIs, receive direct rates, and pay for the request directly from the Solana wallet.

The service supports select Google Cloud APIs, including Gemini, BigQuery, BigTable, Cloud Run, and Vertex AI, allowing agents to access AI data, data storage, cloud infrastructure, and onchain data in a single marketplace.

The platform includes more than 50 community API enablers in e-commerce, market data, communications and blockchain infrastructure.

Pay.sh works as an API proxy built on Google Cloud, sitting in front of services like BigQuery, Gemini and Cloud Run. Instead of relying on traditional credentials, the agent's Solana wallet acts as its identity, while payments via x402 allow requests through an authenticated endpoint with reasonable limits, quotas, and access controls.

Settlement occurs in stable coins on Solana, with suppliers receiving funds after settlement. According to the Solana Foundation, the gateway is built on open standards, including x402 and MPP, which are agents for machine-native payments and API commerce.

The startup adds to its growing push to build a payment infrastructure for AI agents as the software moves toward autonomous workflows. Solana describes x402 as an open payment protocol built on top of the HTTP 402 status code, which allows APIs or web services to request payment before serving content.
