Solana and Google Cloud Launch Pay.sh for AI Agent Payments

The Solana Foundation and Google Cloud launched Pay.sh, a pay-as-you-go marketplace that allows AI agents to pay per API call in dollar-pegged stablecoins on the Solana blockchain using the x402 protocol. The platform replaces pre-funded accounts and subscription keys with on-demand, per-call payments settled on Solana.

Pay.sh extends the x402 standard into a unified registry that lists Google Cloud endpoints alongside more than 50 community API facilitators. Each API call clears in a dollar-pegged stablecoin, while listed facilitators handle billing and settlement on Solana’s low-latency network. The marketplace is live and open to developers without a waitlist.

The service includes a command line interface and integrates with several AI systems and services. It supports Google offerings such as BigQuery and Vertex AI and works inside agent frameworks and models including Gemini, Claude Code, Codex, Openclaw and Hermes. Agents can browse the registry and transact without further technical integration beyond the marketplace requirements.

For enterprises, Pay.sh lets data owners publish endpoints-such as BigQuery-through the x402 registry while facilitators govern billing and access control. Data owners can expose endpoints to external agents without handing over raw data and receive payments in dollar-pegged stablecoins instead of traditional invoices.

The rollout follows recent technical and commercial ties between Solana and Google Cloud. Google has joined the Solana network as a validator, and the Solana Foundation has released an agent toolkit for developers. Pay.sh builds on those integrations and expands the x402 protocol, which had initial backing from Coinbase and Cloudflare, into a commercial registry.
