  title: DeBounce Email Validation Bulk API
  description: 'DeBounce is an email validation and verification REST API. Requests are authenticated with an API key passed as the "api" query parameter; every response carries a "success" flag and a "debounce" object holding the result or the error. This document covers asynchronous bulk list validation on bulk.debounce.io: submitting a hosted CSV/TXT list URL for processing and polling the resulting list_id for status and the completed download link.'
