Solana and Google Cloud Launch Stablecoin API Payments for AI
Pay.sh, powered by the x402 protocol, enables AI agents to authenticate and pay for API access directly with stablecoins, replacing traditional credentials with machine-to-machine payments.
Key Takeaway
AI agents can now pay for APIs directly with stablecoins, cutting out traditional authentication friction.
AI agents can now pay for API access with stablecoins after Solana and Google Cloud launched Pay.sh, a payment tool designed for machine-to-machine transactions.
The system needs just one minute for an agent to link a wallet and start using paid APIs. AI tools like Claude Code and Gemini can authenticate and pay for services without traditional credentials — each transaction becomes its own authorization. Pay.sh replaces usernames and passwords with direct payments.
The x402 protocol powering the tool was incubated by Coinbase and is now managed by the Linux Foundation. Tempo and Stripe contributed to the machine payment protocol development.
The platform already integrates over 50 community-sourced third-party APIs including Helius, Alchemy, Dune Analytics, Nansen, PayAI, Crossmint, Merit Systems, Corbits, Moonpay, Sponge Wallet, ATXP, and Tektonic Company. Real-time pricing discovery happens in a unified marketplace where APIs compete.
Google Cloud has been backing Solana infrastructure for years. The cloud giant runs a validator node, makes blockchain data accessible through BigQuery, deployed Solana nodes across its global data centers for high availability, and built specialized blockchain development tools for the network.
