Free email finder
Search public LinkedIn profiles and get one verified work email per person. 3,000 credits a month with no card, you pay only on a hit, and credits roll over instead of resetting each month.
What a free email finder should actually do
A free email finder should hand you an address that receives mail, not a guess dressed up as a fact. This one searches public, logged-out LinkedIn profiles by job title, company, or keyword, then finds and checks one work email for each person it returns. No LinkedIn account, no cookie, no browser plugin.
Every address gets a live check before it comes back. If it passes, you get it. If no address verifies, or the domain accepts everything so a real check is impossible, the email field returns null and the profile data still comes through. A short list of addresses that actually receive mail beats a long list of maybes, because bounced sends hurt your sender reputation.
One thing to be clear about: these emails come from public LinkedIn person data. Google Maps records carry a business name, phone, website, and address, but Maps has no email field, so no Maps result from any tool includes one.
One request, and what comes back
Here is a search and the same rows shown as CSV first, then JSON. The people are masked to protect real humans, so first name plus last initial, with starred profile URLs and domains. The shape is real.
The second row is the point. No address verified for that person, so the email is null and the profile still comes back. Each row carries these fields:
Free credits that keep, not credits that expire
Most email-finder plans, Hunter among them, run on a monthly credit allowance where anything you did not use resets at the end of the month. CrustAPI credits work the other way. They roll over and never expire, so a slow month is not money burned.
| Monthly-reset plans | CrustAPI | |
|---|---|---|
| Unused credits | reset each month | roll over, never expire |
| Free tier | varies by provider | 3,000 every month, no card |
| Charged for | each lookup on the plan | results only, empty search is free |
| Email quality | found or guessed, depends on tool | one verified work email, or null |
| Data source | database plus lookups | live public LinkedIn person data |
Same key runs the rest of the set: people search · the LinkedIn email finder · the email scraper.
Free to start, cheap to scale
Every account gets 3,000 free credits a month, no card. When you outgrow that, packs are prepaid and self-serve: 25k for $49, 100k for $149, 500k for $549, and 2.5M for $1,999, all ex-tax. That entry pack works out to about $1.96 per 1,000. You are billed only when a search returns results, an empty search costs nothing, and credits never expire.
When another tool is the better call
You want a full app, not an API: if you need a browser extension, a large built-in contact database to browse, and a sequencer to send from inside one product, tools like Hunter, Apollo, and Lusha are built for exactly that and do it well. CrustAPI is the data layer. You bring the workflow, we return one verified email per person, and you keep every row you pull.
CrustAPI is a one-person company. If a result ever looks wrong, email support@crustapi.com and the person who built it will answer.

Point it at your real market
Search the titles you actually sell to and see how many verified emails come back. The free tier covers a real test, and the JSON decides, not this page.
