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 an open standard, agents can find APIs, access them, and pay for their usage with stablecoins on the Solana network.

Pay.sh uses the x402 protocol as a gateway—an open standard for AI payments developed by Coinbase. The service is compatible with a similar solution called Machine Payments Protocol (MPP), created by Tempo and Stripe.

Users can link their Solana wallets to various platforms, including Google Gemini and public systems like Openclaw, and top up their balance using credit cards or stablecoins.

After that, agents, whether supervised or not, can browse the API marketplace and access services without needing to create an account or pay for a subscription.

How It Works

Pay.sh is a protocol designed for bots. An API proxy runs on the Google Cloud Platform (GCP), acting as an intermediary between the AI agent and Google Cloud's server solutions: BigQuery for data analysis, Gemini for LLM calls, and Cloud Run for containerized applications.

The proxy authenticates and modifies the agent's request before sending it to GCP, and also adds payments through x402 or MPP.

"Your agent's Solana wallet serves as its identifier. This means there's no need to create a Google account or manage updatable credentials. No subscriptions or minimum fees. The agent spends exactly what it needs," the announcement states.

In addition to the official Google Cloud APIs, Pay.sh will connect with 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 access five sources in a single request and pay "fractions of a cent for each call." This allows them to choose the best offer and not rely on a single provider.

Recall that in April, the developers of x402 launched a marketplace for applications and services aimed at enhancing the utility of AI agents.
