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

TLDR

• Pay.sh lets AI agents access and pay for APIs using Solana stablecoins.
• Google Cloud and Solana Foundation developed Pay.sh for agent payments.
• The system uses Solana wallets as both payment tools and agent identity.
• Pay.sh supports Google Cloud APIs including Gemini, BigQuery and Cloud Run.
• More than 50 community API providers are available through the Pay.sh system.

Google Cloud and the Solana Foundation have launched Pay.sh, a new pay-as-you-go system that allows AI agents to access and pay for APIs using stablecoins on Solana.

The system is designed to let software agents discover services, make API calls, and settle payments without opening accounts, managing subscriptions, or relying on traditional billing systems. Pay.sh uses Solana wallets as both identity and payment tools for AI agents.

The launch comes as companies explore agentic commerce, where AI systems perform tasks, access services, and make payments on behalf of users or businesses.

Pay.sh Lets AI Agents Pay Per API Call

Pay.sh allows users to connect Solana wallets to AI platforms, including Google Gemini and public agent systems. Wallets can be funded with stablecoins or credit cards.

Once connected, AI agents can browse API services, compare pricing, and pay only for what they use. Instead of paying a monthly subscription, an agent can pay small amounts for individual API calls.

The system uses the x402 protocol, an open AI payments standard incubated by Coinbase. It is also compatible with the Machine Payments Protocol developed by Tempo and Stripe.

Payments are processed through Solana, allowing stablecoin settlement within seconds and at low cost.

Google Cloud Runs API Proxy Layer

Pay.sh operates through an API proxy hosted on Google Cloud. The proxy sits between the AI agent and backend services, including Gemini, BigQuery, BigTable, Vertex AI, and Cloud Run.

The proxy authenticates requests, routes them to the correct service, and adds payment logic through x402 or MPP. This allows API providers to charge per request without requiring traditional accounts or API keys.

The Solana Foundation said an agent’s wallet can act as its identity, removing the need for separate Google account creation or rotating credentials.

The platform also includes rate limits and access controls, giving service providers a way to manage usage while accepting machine-driven payments.

More Than 50 Community APIs Included

Pay.sh will also connect to more than 50 community API providers. These include communications tools, e-commerce services, blockchain infrastructure providers, and data platforms.

Blockchain-related providers include Helius, Alchemy, The Graph, Dune Analytics, and Nansen. These services can support market research, onchain data, trading tools, wallet activity, and blockchain queries.

The model gives AI agents the ability to use several services in one workflow while paying small amounts for each call. A Solana Foundation representative said agents could use multiple sources per query and pay fractions of a cent for each request.

The launch places Solana and Google Cloud inside a growing market for AI payments infrastructure. The next phase will depend on developer adoption, API provider participation, and whether stablecoin-based machine payments become practical for business use.
