​
Overview

This API supports email verification and task status checks. Submit an email for verification and use the returned task ID to poll for results.

​
Creating an API key

Create and manage your API keys in the Deliverable dashboard:
  1. Go to API keys.
  2. Sign in or create an account if needed.
  3. Create a new API key. Copy and store it securely; it is shown only once.
Use this key in the x-api-key header for all API requests.

​
Base URL

Use the base URL for your environment (for example, https://api.deliverable.co for production). Check the API documentation or your dashboard for the exact URL.

​
Authentication

Send your API key in the x-api-key header with every request: 
"security": [
  {
    "apiKeyAuth": []
  }
]

​
Requirements
