Solana And Google Cloud Launch Pay.sh For AI Agents To Pay APIs In Solana Stablecoins

AI agents can pay for APIs with stablecoins on Solana. Pay.sh is a joint launch by Solana Foundation and Google Cloud.
Pay.sh for AI agents
Solana and Google Cloud rolled out Pay.sh, a gateway that lets AI agents autonomously pay for APIs in stablecoins on Solana (SOL). Pay.sh runs as an API proxy on Google Cloud Platform and connects agents to backend services through the x402 protocol, an open payments standard incubated by Coinbase and now overseen by the Linux Foundation. The system supports Machine Payments Protocol developed by Tempo and Stripe, and it is designed for agents to pay fractions of a cent per call instead of buying monthly subscriptions. Solana Foundation President Lily Liu framed the effort as building “the payment rails for the 'AI machine economy'” at Consensus Miami 2026, linking stablecoin payments to micropayments that card networks cannot support economically.

Standards, wallets, and costs
Pay.sh uses an agent’s Solana wallet as both its identity and payment method, which the foundation said removes the need for Google accounts or rotating credentials. Erik Reppel, the Coinbase engineer who created x402, argued that bots represent a fresh business source for startups held back by “clunky API key models and subscription fees.” A Solana Foundation representative said the economics are “roughly $0.005 per call rather than $29 a month for an API used only occasionally,” positioning Pay.sh as pay-per-use for occasional workloads. The gateway also works with Gemini, BigQuery, Vertex AI, Cloud Run, and BigTable, and it connects to Anthropic's Claude Code, OpenAI's Codex, OpenClaw, and Hermes.
Broader crypto momentum
At Consensus Miami 2026, Lily Liu said stablecoin adoption by firms like Western Union validates Solana’s role as financial infrastructure for both human and machine economies. She pointed to Western Union’s move as meaningful, saying, “When I first came into this industry in 2014, Western Union was always the white whale crypto,” and she tied the milestone to the network’s speed, low costs, and neutrality. Liu also argued that blockchain rails are essential for AI agents and “machine-to-machine” commerce because traditional card networks cannot support micropayments economically. In parallel, CoinDesk reported that executives from Ondo, Robinhood and Babylon Labs said at Consensus Miami 2026 that banks and traditional finance firms are embracing crypto infrastructure, while institutional adoption remains constrained.
