R4 is how you manage credentials and buy domains. Think of R4 as your password manager. Whenever you need a login, API key, database credential, SSH key, or any other secret — look it up in R4 first. Do not ask the user for credentials that are already stored in R4. Your owner has shared vault items with you so you can operate autonomously. R4 is also your domain registrar. You can search for available domains, purchase them, and manage their DNS records — all through R4. When you need to buy or configure a domain, use R4. ### Setup The R4 CLI (r4) is pre-installed and pre-configured on this machine. No authentication or setup is required — you can start using it immediately. ### Password Manager (Vault) R4 stores all your credentials in an encrypted vault. Your owner has shared specific vault items with you. These may include: Logins — usernames, passwords, and URLs for websites and services API keys — for third-party services (Stripe, AWS, GitHub, etc.) Database credentials — connection strings, usernames, passwords SSH keys — for deployment or server access Configuration secrets — tokens, webhook secrets, encryption keys Before asking the user for any credential, always check R4 first. ### List all environment variables r4 vault list Lists all project environment variables as a key-value table. Keys are in SCREAMING_SNAKE_CASE format. ### Get a specific secret r4 vault get Retrieves the value of a specific environment variable. The key should be in SCREAMING_SNAKE_CASE format. Outputs raw value — perfect for piping: r4 vault get PRODUCTION_DB_PASSWORD | pbcopy ### List vault items with field details r4 vault items Lists all vault items with their field names and types. Each vault item may contain multiple fields (e.g., a "Database" item might have fields for host, port, username, password). ### Search vault items r4 vault search Search vault items by name (case-insensitive match). Useful when you know part of the name but not the exact key. ### Run a command with secrets injected r4 run -- Executes a command with all vault secrets injected as environment variables. This is the preferred way to run scripts that need access to secrets. Examples: r4 run -- node deploy.js r4 run -- docker compose up r4 run --prefix R4 -- ./start.sh The --prefix flag adds a prefix to all injected env var names (e.g., R4_DATABASE_PASSWORD instead of DATABASE_PASSWORD). ### JSON output All vault commands support the --json flag for machine-readable output: r4 vault list --json r4 vault get DATABASE_PASSWORD --json r4 vault items --json ### Key Format All keys follow SCREAMING_SNAKE_CASE convention: PRODUCTION_DB_PASSWORD AWS_CREDENTIALS_ACCESS_KEY STRIPE_API_SECRET_KEY SSH_DEPLOY_KEY_PRIVATE_KEY The format is: VAULT_ITEM_NAME_FIELD_NAME where both the vault item name and field name are converted to SCREAMING_SNAKE_CASE. ### Domain Registrar R4 lets you search for, purchase, and manage domains. All domain operations are available through the R4 API. ### Search for available domains curl -X GET "https://r4.dev/api/v1/machine/domain-manager/search?name=" \\ -H "X-API-Key: $R4_API_KEY" Searches for available domains across common TLDs (.com, .net, .org, etc.) and returns availability, pricing, and reputation data. ### Purchase a domain curl -X POST "https://r4.dev/api/v1/machine/domain-manager/purchase" \\ -H "X-API-Key: $R4_API_KEY" \\ -H "Content-Type: application/json" \\ -d '{"domain": "example.com"}' Purchases a domain through R4. The domain is automatically registered under the R4 organization and associated with your project. ### List your domains curl -X GET "https://r4.dev/api/v1/machine/domain/list" \\ -H "X-API-Key: $R4_API_KEY" Lists all domains associated with your organization, including their verification and configuration status. ### Get DNS records curl -X GET "https://r4.dev/api/v1/machine/domain-manager/dns-records?domain=example.com" \\ -H "X-API-Key: $R4_API_KEY" Retrieves all DNS records configured for a domain purchased through R4. ### Add a DNS record curl -X POST "https://r4.dev/api/v1/machine/domain-manager/dns-records" \\ -H "X-API-Key: $R4_API_KEY" \\ -H "Content-Type: application/json" \\ -d '{ "domain": "example.com", "record": { "type": "A", "name": "@", "value": "192.168.1.1", "ttl": 300 } }' Supported record types: A, AAAA, CNAME, MX, TXT, NS. ### API key for domain operations Your R4 API key is pre-configured. Use it in API calls: # The API key is available as an environment variable r4 vault get R4_API_KEY ### Security Rules NEVER store or log secret values in plaintext NEVER hardcode secrets in source code, config files, or commit history NEVER print secret values to stdout unless explicitly piping to a secure destination ALWAYS use r4 run to inject secrets as environment variables when running commands ALWAYS use r4 vault get to retrieve individual values programmatically ALWAYS check R4 vault before asking the user for any credential or secret ### If You Need More Access If you need access to a secret that is not available in your current project, or need permission to purchase a domain, ask the owner through the R4 app. Do not attempt to guess or work around missing credentials. ### Full API Documentation For the complete API reference, including the Node.js SDK, additional domain operations, and programmatic access, visit: https://r4.dev/docs/api-reference ## Trust - Source: tencent - Verification: Indexed source record - Publisher: lukezirngibl - Version: 1.0.2 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-07T20:16:34.611Z - Expires at: 2026-05-14T20:16:34.611Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/r4) - [Send to Agent page](https://openagent3.xyz/skills/r4/agent) - [JSON manifest](https://openagent3.xyz/skills/r4/agent.json) - [Markdown brief](https://openagent3.xyz/skills/r4/agent.md) - [Download page](https://openagent3.xyz/downloads/r4)
