Google Cloud, Solana launch Pay.sh for agent stablecoin payments

The Solana Foundation and Google Cloud launched Pay.sh, a payment gateway that allows autonomous software to pay per API call using Solana stablecoins. The service links wallet identities to APIs and records each payment on the Solana blockchain.

Pay.sh operates as an API aggregation and payment layer. Developers and service providers can expose APIs through the gateway while agents locate services, make requests and pay per request in stablecoins. Each payment is executed as an on-chain wallet transaction tied to an API call.

The system removes traditional onboarding steps such as account creation, identity verification and invoice-based billing for those API interactions, letting software transact directly via wallet-based identities.

Google Cloud supplied infrastructure support and enterprise visibility for the project. The company previously added Solana ledger data to BigQuery to let developers and businesses run analytics on blockchain transactions.

The launch comes as firms build payment rails for machine-to-machine commerce. In March, Rishin Sharma, head of AI growth at the Solana Foundation, said, “Payment protocols … are starting to be built,” and pointed to standards such as x402 and the ability for agents to transact directly with stablecoins.

Pay.sh competes with other technical approaches in an early market. Some projects are developing open protocols for per-request crypto payments, while established payment firms offer agent-focused billing tied to fiat accounts and account-based systems.

Adoption requires action by both API providers and agent developers. Service providers must opt to accept stablecoins and integrate with the gateway. Developers must add wallet support and payment logic to their agents.

Security, regulatory oversight of crypto payments and integration with enterprise billing and compliance systems are practical challenges cited by early users and observers. Those factors affect how providers and businesses decide whether to accept wallet-based, per-request settlements.

Dan Albert, executive director of the Solana Foundation, said, “The Solana ecosystem is growing rapidly,” and noted that broader access to blockchain data through cloud services could support wider use.

Pay.sh provides a test case for on-chain, per-request micro-payments between machines. Wider use will depend on API providers listing services on the gateway and developers building agent-native wallets and payment flows.
