Use cases
Every workflow below already knows the person and the company. All that is missing is a way to reach them — and a straight answer about how much that address can be trusted.
Every leads tool hands you a person and a company and then goes quiet. This is the call that closes the gap — one lookup per contact, priced per answer, so a list with poor coverage costs you less rather than the same.
Run it after whichever sourcing tool you already use. Send to verified, hold accepts-all for a warmer channel, and treat unverified as a name to confirm another way.
Exports from an old system routinely carry names and companies but empty email columns. Filling them in by hand is a week of work; filling them in blind is a bounce rate that follows your domain around for months.
Because a lookup that finds nothing is free, running a repair pass over a messy export costs you only for the rows it actually fixes.
You have a name, a current employer, and a profile with no contact details. A pattern lookup against the employer's domain is usually the shortest honest path to an inbox.
The verification status matters more here than anywhere: a bounced approach to a passive candidate is a first impression you do not get to retake.
An agent that has researched a company and picked the right person still needs somewhere to send the result. This is that step, callable over MCP or paid per call in USDC with no account at all.
The status field is machine-readable for exactly this reason — an agent can branch on verified versus accepts-all instead of treating every answer as equally good.
An accepts-all result tells you something useful even when it is not a confirmation: this domain will swallow anything you send, so nobody's verification tool can vouch for it.
That is a signal for how you plan the campaign, not a dead end — it just means confidence has to come from somewhere other than an SMTP probe.
Enumerating a domain — sweeping it to discover whoever happens to have a mailbox there. Email Finder answers one named person at one named company, deliberately. If you need a list of everyone at a company, this is not the tool, and we would rather say so than sell you something adjacent.
