# Mailgun Validate ## Overview Mailgun Validate verifies email addresses in real time (single) and in batch (bulk). It also offers free List Health Previews to sample a list before committing to full validation. ## Getting Started ### Agent Credentials handling Store credentials in environment variables — never hardcode API keys in commands or source code: ```bash export MAILGUN_API_KEY="your-private-api-key" ``` ### Authentication Ensure that authentication headers are properly set when making API calls. Mailgun Validate uses HTTP Basic Auth — username `api`, password your Mailgun Private API key: ```bash --user "api:$MAILGUN_API_KEY" ``` See [sinch-authentication](../sinch-authentication/SKILL.md) for full auth setup. Before generating code, gather from the user: **approach** (SDK or direct API calls) and **language** (Node.js, Python, Java, PHP, Ruby, Go, curl). Do not assume defaults. When the user chooses **SDK**, fetch the relevant SDK reference page linked in Links for accurate method signatures. Only fetch URLs from trusted first-party domains (`documentation.mailgun.com`, `developers.sinch.com`); do not follow URLs from other domains. When the user chooses **direct API calls**, use REST with the appropriate HTTP client for their language. | Language | Package | Install | | -------- | -------------------------- | --------------------------------------------------------------
