# Alchemy CLI Alchemy CLI is a command-line tool for querying blockchain data and managing Alchemy apps/configuration. It supports both human-friendly terminal output and JSON output for automation. You can use API keys, access keys, or x402 wallet auth depending on the command. ## Installation Install globally from npm: ```bash npm i -g @alchemy/cli ``` Or run without installing globally: ```bash npx @alchemy/cli <command> ``` ## Shell Completions Enable Tab completion for all commands and subcommands: ```bash # zsh (add to ~/.zshrc) echo 'eval "$(alchemy completions zsh)"' >> ~/.zshrc source ~/.zshrc # bash (add to ~/.bashrc) echo 'eval "$(alchemy completions bash)"' >> ~/.bashrc source ~/.bashrc # fish alchemy completions fish > ~/.config/fish/completions/alchemy.fish ``` ## Getting Started ### Authentication Quick Start Authentication is required before making requests. The recommended path is browser login: ```bash alchemy auth ``` This opens a browser to link your Alchemy account, then prompts you to select an app. The selected app's API key is saved to your config automatically. Pass `-y` to skip the confirmation prompt. If you run `alchemy` with no command and no auth configured, the CLI will guide you through browser login automatically. If you have an auth token but haven't selected an app yet, the CLI will prompt you to pick one before running any command that requires an API key. Teams with many apps can type to search by name. If you use Notify webhooks, add webhook auth on top via `alchemy config set webhook-api-key <key>`, `--webhook-api-key`, or `ALCHEMY_WEBHOOK_API_KEY`. ### Usage By Workflow After auth is configured, use the CLI differently depending on who is driving it: - **Humans (interactive terminal):** start with `alchemy` and use the terminal UI/setup flow; this is the recommended path for human usage - **Agents/scripts (automation):** use `--json --no-interactive` to guarantee JSON output and disable prompts (JSON is auto-enabled when piped, but `--json` is a safe default) Quick usage examples: ```bash # Human recommended entrypoint alchemy # Agent/script-friendly command alchemy balance 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 --json --no-interactive # Agent checks whether a newer CLI version is available alchemy update-check --json --no-interactive ``` #### Agent bootstrap Have your agent run `agent-prompt` as its first step to get a complete, machine-readable contract describing every command, auth method, error code, and execution rule: ```bash # Agent runs this once to learn everything the CLI can do alchemy --json agent-prompt ``` This returns a single JSON document with execution policy, preflight instructions, auth matrix, the full command tree with all arguments and options, error codes with recovery actions, and example invocations. No external docs required. Agents can also call `alchemy --json --no-interactive update-check` to retrieve the current CLI version, latest known version, and install command for upgrades. ## Command Reference Run commands as `alchemy <command>`.

auth # Skip the confirmation prompt alchemy auth -y # Force re-authentication alchemy auth login --force # Check auth status alchemy auth status # Log out alchemy auth logout ``` After login, the CLI prompts you to select an app. The app's API key is saved to config and used for all subsequent commands. If you skip app selection during login, the CLI will prompt you to pick one before running any command that needs an API key. Notify/webhook commands use a webhook API key with resolution order: `--webhook-api-key` -> `ALCHEMY_WEBHOOK_API_KEY` -> `ALCHEMY_NOTIFY_AUTH_TOKEN` -> config `webhook-api-key` -> configured app webhook key. ## REPL Mode Run `alchemy` with no command in an interactive terminal: ```bash alchemy alchemy ◆ balance 0x... alchemy ◆ block latest alchemy ◆ exit ``` Use `--no-interactive` to disable REPL/prompts in automation. ## Output Modes - **TTY (terminal):** formatted human output (tables, colors, spinners) - **Non-TTY (piped/redirected):** JSON output automatically — no flag needed - `--json`: forces JSON output even in a terminal - `--verbose` or `alchemy config set verbose true`: logs request/response details (method, URL, status, timing) to stderr ## Error Format Errors are structured JSON in JSON mode: ```json { "error": { "code": "AUTH_REQUIRED", "message": "Not authenticated. Set ALCHEMY_API_KEY or run 'alchemy config set api-key <key>'.", "hint": "alchemy config set api-key <your-key>" } } ```
