USDC bridge and pay-per-call financial tools.

## How it works

An agent with a compatible wallet discovers Liquid Agent APIs or MCP tools and pays for supported services per call through x402. Its API includes a USDC bridge and other financial tools.

## At checkout

Services return payment terms for a compatible wallet to approve and submit. The bridge and other tools have their own terms; this is a service API rather than a general-purpose card checkout.

## Security

Payment authorization is signed by the caller’s wallet. Users should inspect the destination, amount and service terms; the public API description does not establish wallet custody or spending safeguards for every client.
