What it does

APIddress is an email validation API for developers: one request returns the full verdict — syntax, domain/MX, disposable, role-based, typo detection, and spam-trap risk — as a transparent checks object, not a black-box score. The private beta is opening soon : request access at apiddress.com and get a key as soon as it opens. Free during beta, no credit packs, and nothing ever expires. Follow here to catch the public launch.

EmailDetective – A Email Validation API2024 · emaildetective.io · ▲6
Hello, I'm Andrew, owner of EmailDetective. I was looking for an API solution for email validation/scoring for multiple mailing lists. I noticed a lot of the email validation services out there: - Do not have an API - Are behind a paywall to try the API - Are priced way to high - Have inconsistent or non-intuitive APIs So I decided to create my own solution. This is my first time announcing EmailDetective, so I am looking for any general feedback, issues you might have run into and if you find this service useful. And yes you can try it out for free without signing up :)

Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
