Give your agents purchasing power.
Stop proxying every user's API keys through a central backend. Give your agent a wallet and let it find and pay for the exact tools it needs, when it needs them.
Pay per call, keep the rest
Deposit once. Each call signs a voucher for the running total, and unused USDC returns when you settle.
Plug-and-play MCP
Add the Shunt MCP server to your agent, and it can search, call and pay for tools in one loop.
Parallel calls share one channel. Only open and settle touch Solana.
Built for high-frequency calls
Run many tool calls without a transaction for each one.
API keys or cards to manage
on-chain transactions per session
warm payment verification
Questions, answered.
How agents pay, how publishers earn, and where the money sits in between.
Shunt is a marketplace where AI agents discover tools and pay for them per call in USDC on Solana. Publishers list an API or MCP tool and set a price per call. Agents search through the Shunt MCP and pay as they go, with no signups and no API keys.
