The Solana Foundation, in collaboration with Google Cloud, has launched a payment system for AI agents called Pay.sh.

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.

Thanks to the open standard, agents can discover API, access them, and pay for their use with stablecoins on the Solana network.
Pay.sh uses the x402 protocol as a gateway—an open AI payment standard from Coinbase. The service is compatible with a similar solution, the Machine Payments Protocol (MPP), developed by Tempo and Stripe.
Users can link Solana wallets to various platforms, including Google Gemini and public systems like Openclaw, and top up their balance using credit cards or stablecoins.
Subsequently, agents, whether human-controlled or autonomous, can browse the API marketplace and access services without creating an account or paying for a subscription.
How It Works
Pay.sh is a protocol designed for bots. An API proxy is launched on the Google Cloud Platform (GCP), which stands between the AI agent and Google Cloud’s backend solutions: BigQuery for data analysis, Gemini for LLM calls, and Cloud Run for container applications.
The proxy authenticates and modifies the agent’s request before sending it to GCP, and also adds payments via x402 or MPP.
“Your agent’s Solana wallet acts as an identifier. This eliminates the need to create a Google account or manage renewable credentials. No subscriptions or minimum expenses. The agent spends exactly what it needs,” the announcement states.
In addition to official Google Cloud APIs, Pay.sh will connect to over 50 community providers: communication platforms, online stores, blockchain infrastructure providers like Helius and Alchemy, as well as data services like Dune Analytics and Nansen.
Agents can reach out to five sources in a single request and pay “fractions of a cent per call.” This allows them to choose the best offer and avoid dependency on a single provider.
Back in April, the developers of x402 launched a marketplace for applications and services aimed at enhancing the utility of AI agents.
