Solana Foundation and Google Cloud have launched Pay.sh, a new payment gateway that allows AI agents to access and pay for APIs on a per-request basis using stablecoins on Solana. The launch addresses a growing issue in AI infrastructure as autonomous agents increasingly rely on dozens of external services but still face traditional barriers such as account creation, API keys, subscriptions, and billing management.
The system supports Google Cloud services including Gemini, BigQuery, Vertex AI, Cloud Run, and BigTable, according to Solana Foundation’s official announcement. Instead of managing separate accounts and credentials, AI agents can fund a Solana wallet and pay directly for API calls through automated payment protocols designed for AI systems.

For the first time agents can discover, access, and pay-per-request for APIs from Google Cloud including Gemini, BigQuery, Vertex AI, and more using stablecoins on Solana.

Pay.sh operates as an API proxy layer on Google Cloud infrastructure while using Solana wallets as both the payment and identity layer. Solana Foundation said the gateway settles payments in stablecoins within seconds and applies enterprise controls such as rate limits and access permissions before requests reach backend services.
The launch reflects a broader shift in how AI developers are approaching software access. Most enterprise APIs still rely on monthly subscriptions and credential management designed for human users rather than autonomous systems making thousands of small requests across different services.
Pay.sh uses a pay-per-call structure where agents consume only the resources they use. Solana Foundation said the service also supports more than 50 external API providers across blockchain infrastructure, ecommerce, communications, and data intelligence.
The platform integrates with AI interfaces including Gemini, Claude Code, Codex, Hermes, and Openclaw.
The launch places Solana deeper into the growing competition to build payment infrastructure for AI agents. Coinbase recently expanded x402, an HTTP-based payment standard for machine-to-machine transactions that has already processed millions of agent-driven payments across Base ecosystem infrastructure. Stripe and Tempo have also promoted the Machine Payments Protocol, or MPP, as firms test automated billing systems for AI software.
Google itself entered the sector earlier this year through its Agent Payments Protocol initiative alongside Coinbase, Mastercard, PayPal, and the Ethereum Foundation.
If you have a data repository in Google Cloud, https://t.co/wP8Q8614MS lets you expose your own private datasets to AI agents via the x402 protocol, with the facilitator handling payment so your data stays secure.

Still, the model remains early-stage. Most enterprise software providers continue to rely on conventional billing systems, and developers may hesitate to expose sensitive infrastructure directly to autonomous agents despite payment controls and verification layers.
That limitation matters because Pay.sh’s success depends not only on stablecoin settlement speed, but also on whether enterprises accept wallet-based authentication as a reliable replacement for traditional API credential systems.
The launch also signals that stablecoins are moving beyond trading and remittances into backend internet infrastructure, where AI systems increasingly require automated access to compute, data, and cloud services.
