Hosted in the EU. Full stop.
Many verification APIs run out of US data centers. Every request here runs on servers in Germany, so your data never leaves the EU.
Honest results in real time: syntax, MX, SMTP, catch-all, typos. EU-hosted, zero retention. And when a mailbox is uncertain, we tell you.
No credit card. 1,000 tokens included.
Every verification, scored and tracked in real time. This is the exact overview you get once you're in, filled with sample activity.
Enable only the checks you need. You only pay for what you enable.
Create an account, grab your key. No credit card required to start.
One API call per email, or drop a CSV. Get a 0–100 deliverability score.
Your code and your agents call the same endpoint and get the same honest verdict: valid, invalid, risky, or unknown, never a guess dressed up as certainty.
Drop it into any MCP client's toolbox. No wrapper, no glue code.
Metered per verification, so an agent running unattended only spends what it actually checks.
Syntax, MX, then a real SMTP negotiation with the receiving server: the verdict lands live, never from a frozen list.
Disposable, catch-all, role addresses: all flagged, so a technically valid address never passes as safe.
gmial.com corrected to gmail.com, before the email ever bounces.
Every check rolls into a single 0-to-100 score, ready to wire into your business logic.
Pick a monthly plan and choose which checks to run. You pay for the checks, not the email count.

No inflated accuracy claims, no data hoarding, no fabricated guesses. Just an API built the way developers actually want it.
Many verification APIs run out of US data centers. Every request here runs on servers in Germany, so your data never leaves the EU.
The usual approach keeps your lists on file, and sometimes resells them. We keep only an irreversible hash, used for deduplication and aggregate stats. Nothing to resell, nothing to leak.
Many tools return a confident valid even when they can't actually know. A mailbox that can't be conclusively probed comes back risky or unknown here, documented, never a fabricated pass.
The usual approach locks you into a dashboard with no real API underneath. One authenticated POST to /api/verify returns JSON, and every error carries a typed key, never a localized surprise.
Every address runs through syntax, MX, SMTP mailbox probing, disposable-domain detection, role and free-provider flags, catch-all detection, and typo correction. Large providers like Gmail, Outlook, and Yahoo block direct mailbox probing to prevent enumeration, so those addresses get a valid verdict with a capped score instead of a fabricated guess. When we are not sure, we say so.
