Solana Foundation and Google Cloud Launch Pay.sh, a Native Payment Rail for AI Agents

Cloud-scale AI infrastructure now has a native payment rail on Solana. The Solana Foundation and Google Cloud on May 5 launched Pay.sh, an open-standard gateway that lets autonomous agents discover, access, and pay for APIs per request using stablecoins, with a Solana wallet serving as the agent's identity credential in place of accounts or subscription plans.

"Agentic payments are one of the most important frontiers in the agentic stack," said Rich Widmann, Head of Strategy, Web3, at Google Cloud. Pay.sh operationalizes that claim: an agent links a Solana wallet, funds it via credit card or stablecoin in under 60 seconds, and can immediately begin calling APIs, with each request settling as a micro-payment rather than drawing down a pre-paid subscription.

How Pay.sh Routes Agent Payments Through Google Cloud

Pay.sh sits as an API proxy layer on Google Cloud infrastructure. When an agent calls an endpoint, the gateway authenticates the request against the wallet balance, modifies the HTTP headers, processes the micro-payment, and forwards the call in a single round-trip. No KYC, no credential rotation, no minimum spend. Payment is the credential.

The protocol layer runs on x402, the machine-payment standard originally developed by Coinbase that uses the HTTP 402 status code to signal a payable resource, and is also compatible with Stripe and Tempo's Machine Payments Protocol (MPP). Google Cloud APIs available at launch include Gemini, BigQuery, BigTable, Vertex AI, and Cloud Run. The ecosystem spans more than 50 community providers including Helius hSOL$88.26-1.2% Helius, Alchemy Alchemy, Dune Analytics, and Nansen.

AWS AgentCore and MoonPay Enter the Same Race

The launch lands as an industry-wide push to build agentic payment infrastructure. Amazon Web Services launched a preview of Bedrock AgentCore Payments, built with Coinbase and Stripe and settling on Base and Solana, two days after Pay.sh, while MoonPay has introduced MoonAgents Card, a virtual Mastercard linking stablecoin on-chain wallets to AI agent spending. These are parallel bets on the same thesis: agents will be significant economic actors, and they need their own payment primitives.

Pay.sh's Solana-native positioning reflects meaningful existing traction. The x402 protocol has processed more than 35 million transactions and over $10 million in volume on Solana since mid-2025, part of a broader 165 million x402 transactions across roughly 69,000 active agents. Much of that volume currently runs on Base, Coinbase's Ethereum layer 2. Pay.sh is a direct bid to accelerate Solana's share.

x402 Moves to Linux Foundation With Backing From AWS, Stripe, and Visa

The x402 standard is moving to the Linux Foundation under a purpose-built x402 Foundation, with stated backing from AWS, Google, Stripe, Visa, Mastercard, Microsoft, Shopify, and Circle, among others. That governance structure reduces the risk of any single company controlling the payment protocol that agentic applications are building around, and positions x402 as infrastructure rather than a proprietary product.

For developers building on Solana today, Pay.sh lowers the entry cost for integrating enterprise data and compute. An agent that needs a one-time BigQuery query or a single Gemini inference call can make that call without provisioning an account first. The infrastructure for it is now live.
