Solana Foundation and Google Cloud have launched Pay.sh, a stablecoin payment gateway that lets AI agents access and pay for APIs on a per-request basis.
Summary
- Pay.sh lets AI agents pay for Google Cloud services and APIs using stablecoins on Solana.
- The service supports per-request payments, helping agents avoid subscriptions, accounts, and minimum spending limits.
- Solana joins Coinbase, Google, Stripe, and MoonPay in building payment rails for AI agents.
The service allows agents to use Solana wallets to pay for Google Cloud tools and other API services without standard accounts, API keys, or subscriptions. Solana said Pay.sh supports Google Cloud APIs including Gemini, BigQuery, Vertex AI, and more.
Pay.sh lets AI agents discover services, check prices, and pay for API access using stablecoins on Solana. The system is built for small payments, including fractions of a cent per request.
That structure gives developers a way to charge for single API calls instead of monthly plans. It also lets AI agents use only the services they need, when they need them.
Solana said the service works through an API proxy on Google Cloud. The setup connects agents to backend services while using a Solana wallet as the payment and identity layer.
The system supports Google Cloud services and more than 50 community API providers. Listed services include blockchain data, cloud tools, AI services, and developer APIs.
x402 and MPP support the payment flow
Pay.sh uses x402, an open payment standard that began at Coinbase and later moved under the Linux Foundation. The protocol uses the HTTP 402 “Payment Required” status code to let apps and AI agents pay directly through web requests.
As featured in recent coverage, x402 joined the Linux Foundation with backing from firms including Google, Stripe, AWS, Visa, and Mastercard. The report said the standard aims to support AI-native internet payments without separate billing flows.
Pay.sh also supports the Machine Payments Protocol, developed by Tempo and Stripe. This gives the service another route for machine-to-machine payments as developers test new models for AI commerce.
The launch adds Solana to the growing competition around stablecoin rails for autonomous software. The network’s low fees and fast settlement are part of the reason it is being used for small API payments.
Coinbase and Google push AI payment standards
The Pay.sh launch follows Coinbase’s own push into AI agent payments. As reported by crypto.news, Coinbase launched Agentic.market, a marketplace that lets AI agents find and buy services using USDC through x402.
That report said x402 had already settled about 165 million transactions across more than 480,000 transacting agents. Most of those transactions took place on Base, Coinbase’s Ethereum layer-2 network.
Google has also worked on AI payment infrastructure through its Agent Payments Protocol. Earlier coverage said Google launched AP2 with a crypto extension developed with Coinbase, Ethereum Foundation, and MetaMask.
That system uses signed payment instructions to help verify user approval when AI agents make payments. Pay.sh now applies a similar machine-payment idea to API access through Solana stablecoin payments.
Stablecoin payments race expands
The launch comes as more crypto and payment firms build products for AI agents. MoonPay has also moved into the sector with tools that let AI agents access wallets and spend stablecoins.
As noted in a recent report on AI and crypto investing, MoonPay introduced MoonAgents Card, a virtual Mastercard product that supports AI-linked stablecoin spending from on-chain wallets.
