mailboxlayer API mentions (5)

  • What's the easiest way to check if an email exist?
    I've found a few "free" APIs which tell you if the email address exists or not, they have a free tier for certain amount of queries. Try https://mailboxlayer.com and https://www.zerobounce.net. Source: almost 4 years ago
  • How to build email validation service with AWS products?
    What I mean by valid is whether it is deliverable or not. Like this https://mailboxlayer.com/. Source: almost 4 years ago
  • Laravel validation and custom rules in Inspector
    In Inspector we use the mailboxlayer.com API to validate emails. The service is also able to detect fake email addresses, temporary addresses, and the actual existence of an email address using MX-Records and SMTP. - Source: dev.to / over 4 years ago
  • How do you validate registration emails in order to avoid fake users?
    You can look into APIs ( example https://mailboxlayer.com/ ) they provide info whether email is from a disposable domain. Source: almost 5 years ago
  • Free for dev - list of software (SaaS, PaaS, IaaS, etc.)
    Mailboxlayer.com โ€” Email validation and verification JSON API for developers. 1,000 free API requests/month. - Source: dev.to / about 5 years ago

OpenRouter mentions (37)

  • Databricks drove down AI coding spend 70%
    Omniagent looks quite similar to OpenRouter (https://openrouter.ai/). - Source: Hacker News / 7 days ago
  • GLM-5.2 is the step change for open agents
    It's very easy to use other providers. See https://openrouter.ai/ which also let's you filter by where the provider is hosted and their data retention policy. - Source: Hacker News / about 2 months ago
  • Testing GLM-5.2 on OpenCode: I'm impressed!
    If you want to try it yourself: grab OpenCode, point it at OpenRouter, select GLM 5.2, and give it a real task instead of a benchmark. The z.ai docs have the rest of the details. - Source: dev.to / about 2 months ago
  • AI Gateways in 2026: a field guide to the 106 cost problem
    Hosted, minimal ops. You want to be calling models in five minutes and you are fine paying a small fee for it. OpenRouter is the marketplace default โ€” 400+ models, ~5.5% on credits. Vercel AI Gateway and Cloudflare AI Gateway go further and charge 0% markup, billing you at provider list price while adding routing and caching on top. - Source: dev.to / 2 months ago
  • Self-hosting OpenClaw: a money trap and two silent failures
    I use OpenRouter as the single door to a pile of models. Its BYOK (bring-your-own-key) feature has a trap. You add your own OpenAI key for a model, flip on "Always use for this provider," and read that as never spend OpenRouter credits. It doesn't mean that. - Source: dev.to / 2 months ago
