polymer-pay-cli

You can proxy paid APIs from the terminal by installing the Polymer Pay CLI, authenticating via device flow or API key, and issuing x402 proxy requests that handle automatic payment for arbitrary endpoints.

The x402 proxy workflow routes arbitrary endpoint requests through the Polymer Pay proxy, automatically handling payment and credentials so you can access paid APIs directly from the command line without manual transaction steps.

You can securely manage API keys and credentials by authenticating with the CLI using an API key or OAuth device flow, which stores your credentials securely for subsequent paid proxy requests.

Yes, a Node.js runtime is required to install and run the CLI tool for paid API proxying. You also need a Polymer Pay account and access to your POLYMER_PAY_API_KEY or OAuth credentials to authenticate.

Yes, you can verify your current authenticated identity by running the whoami command in the CLI, which confirms your active user session before you issue paid x400 proxy requests.

You can revoke stored credentials and switch API proxy accounts by running the logout command in the CLI, which clears your secure credentials and ends your current authenticated session.
