NeverBounce API v4 is one of 5 APIs that [NeverBounce](https://apis.io/providers/neverbounce/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Email Verification, REST, JSON, and Deliverability. The published artifact set on APIs.io includes API documentation and an API reference.

RESTful JSON API for email verification. Provides single email verification (`/single/check`), bulk job verification (`/jobs/create`, `/jobs/parse`, `/jobs/start`, `/jobs/status`, `/jobs/results`, `/jobs/search`, `/jobs/delete`, `/jobs/download`), account credit info, and Proof-of-Engagement (`/poe/confirm`) endpoints. GET and POST are interchangeable; PUT and DELETE are unsupported. Authentication uses a per-integration API key (`secret_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx`) passed via the `key` query/body parameter.
