The Solana Foundation and Google Cloud have introduced Pay.sh, a Solana-based gateway designed to enable AI agents to discover, access, and pay for APIs on a per-request basis using stablecoins. The launch positions Solana as the payment infrastructure for agent software workflows, with Google Cloud APIs including Gemini, BigQuery, Vertex AI, BigTable and Cloud Run among the first enterprise services supported.
The product addresses a bottleneck that has become more visible as AI agents move from passive assistants to autonomous software operators. Even when an agent can search, code, query data, and perform tasks, accessing premium APIs typically requires a human to create accounts, handle billing, handle credentials, and manage subscriptions. Pay.sh attempts to transform this process into a wallet-based payment flow.
“Agents can now instantly discover, access, and pay for any API autonomously, and for the first time support Google Cloud APIs, including Gemini, BigQuery, Vertex AI, and more, using stablecoins on Solana,” the Solana Foundation said in its announcement. “No account. No API key. No subscription required.”
Pay.sh starts with a Solana wallet connected to an AI interface, including Gemini, Claude Code, Codex, Openclaw and Hermes, according to the announcement. Developers can fund the wallet with a credit card or stablecoin, after which an agent can browse a unified marketplace of API endpoints, receive live prices, and pay directly from their balance.
The basic design is simple: the payment works like an identifier. Rather than requiring each API provider to establish a direct billing relationship with each user or agent, Pay.sh acts as a gateway layer between agents and service providers.
The Foundation said Pay.sh functions as an API proxy built on Google Cloud Platform, ahead of Google Cloud services such as BigQuery, Gemini, Cloud Run and others. The user’s Solana wallet acts as the agent identity, while the gateway authorizes requests through verified endpoints and enforces rate limits, quotas, and access controls.
This distinction is important for enterprise APIs. The product is not designed as a way to bypass compliance or security controls, but as a mechanism to manage high-frequency, low-friction payments while preserving provider-side access management.
Solana Powered-Stablecoin Regulations for Agent Trading
Payments are processed in stablecoins on Solana and then reconciled with suppliers, with the announcement emphasizing settlement “in seconds”. Developers only pay for what they consume, while providers avoid manual billing fees for small or irregular usage patterns.

“For the first time, developers can access and pay for individual API calls without billing accounts or KYC,” Vibhu wrote. “Pay.sh gives your device a wallet and financial superpowers with digital dollars on Solana at the root. We’re starting with GCP but you can access 75 other integrations through our open marketplace.”
The Marketplace component is broader than Google Cloud. The Solana Foundation said Pay.sh also includes more than 50 community API enablers in the areas of e-commerce, market data, communications and on-chain infrastructure. Named services include Rye, BigCommerce, Exa, Dune Analytics, Nansen, AgentMail, StablePhone, Helius, Alchemy, QuickNode, Allium and The Graph.
Pay.sh is built on x402 and MPP, which the Foundation described as machine-native payment protocols for agent-API commerce. The registry is open source and service providers can submit endpoints via GitHub or apply to become official Pay.sh API providers.
Launch partners powering community endpoints include PayAI, Crossmint, Merit Systems, Corbits, MoonPay, Sponge Wallet, ATXP and Tektonic Company.
For Solana, the launch gives stablecoin payments another concrete use case for businesses beyond commerce, remittances and consumer transfers.
At press time, SOL was trading at $87.79.
