# NoBounce API (https://nobounceapi.com)

> NoBounce is a fast (~15ms), developer-friendly real-time Email Validation REST API and Bulk CSV Email Verification service. It is 60%–85% more affordable than legacy email verifiers like ZeroBounce, NeverBounce, and Kickbox.

## Core Capabilities
- **Syntax & RFC 5322 Validation**: Instant format verification and display-name extraction.
- **Live DNS & MX Record Verification**: Confirms domain existence and active mail exchange servers with sub-20ms response times.
- **Disposable & Temporary Email Detection**: Blocks 150+ throwaway email providers (`mailinator.com`, `10minutemail.com`, `guerrillamail.com`, `yopmail.com`, etc.) to prevent SaaS free-trial abuse.
- **Role-Based Account Identification**: Flags group/shared inboxes (`support@`, `admin@`, `billing@`, `sales@`, `info@`).
- **Free Webmail Provider Detection**: Distinguishes consumer domains (`gmail.com`, `yahoo.com`, `outlook.com`) from corporate B2B domains.
- **Typo Detection (`did_you_mean`)**: Suggests corrections for common domain misspellings (e.g., `user@gmial.com` -> `user@gmail.com`).
- **Bulk CSV List Cleaning**: Upload CSV/TXT files (comma, semicolon, or tab-delimited) in the web dashboard or via `POST /api/validate-bulk` to validate up to 5,000 emails per batch while preserving original CRM columns.
