The Solana Foundation and Google Cloud have opened Pay.sh, a pay-as-you-go marketplace where AI agents can pay for API calls using stablecoins on the Solana network. The system does away with accounts and subscriptions, instead charging per request through the x402 protocol.
How Pay.sh works
Pay.sh relies on the x402 protocol, originally backed by Coinbase and Cloudflare. It lets AI agents pay for each API call individually, with settlement in stablecoins on Solana's low-latency network. Facilitators handle the transactions on the backend, and developers can use a command line interface to interact with the marketplace.
Services available now
Google Cloud offers three services through Pay.sh: Gemini, BigQuery, and Vertex AI. More than 50 community API facilitators have also joined, giving agents a broad set of endpoints. The list of compatible agents includes Gemini, Claude Code, Codex, Openclaw, and Hermes.
Who can participate
Developers can publish endpoints on Pay.sh immediately — no waitlist. Enterprise data owners can expose private datasets stored on Google Cloud via x402. The facilitator handles billing and access control, and the raw data never leaves the owner's control.
Building on earlier tie-ups
The launch follows two earlier moves: Google Cloud became a Solana validator, and the Solana Foundation released its own agent toolkit. Pay.sh is the latest step in that deepening relationship.
The open question
Recent data shows a slowdown in x402 transaction volume. The big question now is whether enough AI agents will actually start paying for these API calls to keep the marketplace humming.
