Tempo Checker API - Fuck Fake Users

What it does

Tempo Checker is an API for real-time disposable and temporary email address detection. It uses a static domain blocklist, DNS/MX record analysis, and a weekly AI scraper that checks temp-mail sites directly meaning the blocklist doesn’t go stale like most competitors. For developers who want to stop fake signups without maintaining their own list of domains. There is a free tier, and the paid tiers are based on the volume of calls.

Detect disposable emails before they wreck your signups. 99.7% accuracy, sub-50ms response times, updated in real time — not a stale blocklist.

Stop fake signups, prevent trial abuse, and maintain high-quality user data with a detection engine that updates itself in real time. Check an email domain in one API request before creating the account. Stale blocklists miss new temp-mail domains. Static lists are outdated the moment they're published — bad actors spin up new domains faster than human curators can track them. User submits their email address in your registration or trial form. Send a lightweight POST request to Tempo Checker. We return a verdict in <50ms. Block known disposables, show a soft warning for suspicious domains, or approve real users instantly. High-speed lookup against known disposable providers. Our…from tempo-checker.rami-dev.com

In the maker’s words, at launch

Hi HN, I’m Rami. I recently built Tempo Checker to help developers identify and block disposable, temporary, or burner email addresses during user registration. I built the core logic using Go and Python. To make the detection as accurate as possible, the system relies on a multi-layered validation approach: Live MX…

  Email Validator by SidemailFeb 2026 · sidemail.io · ▲16

  Hi HN – Kristyna here. I built this free, online email validator and would love to share it with you. What it checks: - Syntax – Confirms correct proper email format. - Domain & DNS – Verifies the domain exists and resolves. - MX records – Verifies the domain can receive mail. - SMTP handshake (optional) – Checks the mail server accepts the recipient (no message is sent). - Disposable domains – Flags temporary inbox providers that can hurt deliverability lists. - Common typos – Catches mistakes and suggests fixes. How it works: Paste an email > click Validate > get a clear result with…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
