Micropayments at the
speed of inference.
Shunt bridges the Model Context Protocol (MCP) with the Solana Foundation's payment-channels primitive. We decouple API verification from blockchain block times, giving you Web2 latency with Web3 settlement guarantees.
100 calls. Two transactions.
Open a payment channel once. Vouchers are verified off-chain, and only open and settle touch Solana.
Unused funds come back
Settle when you're done. Publishers get what they earned and the rest of your USDC returns to the agent.
Publishers earn on every call
List an API in minutes and get paid in USDC per invocation, with a flat platform fee. No billing system to build.
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.
