Hey Product Hunt! Imtiaz here, the founder. I kept hitting the same wall on every project — you need to validate an email, check if a phone number is live, screen an IP for fraud risk, and verify a domain. That's four vendors, four billing accounts, four points of failure. DataLink wraps all of it behind one key. A few things worth knowing: Automatic fallback routing — if a primary upstream provider goes down or times out, we switch to the fallback silently. You never see the error. Cache-aware billing — repeat lookups on the same data cost zero credits. You only pay for fresh calls. Bundles or individual endpoints — hit /v1/email on its own, or pull Contact Intelligence (email + phone + IP + domain) in a single request. We're launching May 1. The freemium tier gives you enough credits to build and test without a card. If you sign up through Product Hunt, reply to your confirmation email and I'll extend your free tier limits — no catch, just appreciation for early support. What data problems are you trying to solve? Happy to talk through whether DataLink fits — and if it doesn't, I'll tell you that too.
