Authentication Methods

Echo API Key

The Echo API Key method creates an API key via your web browser:

1. Run echodex login and select "Echo API Key"
2. Your browser will open to echo.merit.systems
3. Sign in and create an API key
4. The key is securely stored in your OS keychain

WalletConnect

The WalletConnect method uses the X402 payment protocol:

1. Run echodex login and select "WalletConnect"
2. Scan the QR code with your mobile wallet (e.g., MetaMask, Rainbow)
3. Approve the connection
4. Pay for AI usage directly from your wallet

@zdql can you please review it, and give me some feedbacks

[zdql]

Overall, really nice work @sachigoyal ! Left two notes, While you fix those up I will try to get this merged and you paid on terminal today!

[sachigoyal]

@zdql hey added two new features

• resume command now displays prev messages
• local wallet (self custody)

also updated the readme of it so that you can get more ideas about the implemenation
you can give it a try if you want

just in case you wanna try directly in the monorepo, let me help you with few notes

1. cd templates/echo-cli
2. pnpm install --ignore-workspace
3. pnpm approve-builds and select all and approve (definitely needed for keytar to work)
4. pnpm start should display the help command output
5. pnpm start login to see 3 auth options (3rd is the local wallet)

the reason i didnt add init local wallet command is to preserve the convention of the code. so it will be the 3rd option of authentication. also i kept in mind the security aspects, so users get pretty good warnings and everything that deals with the private key

let me know you opinions, and how else should i modify the docs website to communicate better

thanks
