HOW IT WORKS

Junk is free
Duplicates and rows that are not a domain never enter the bill.
Free sample
A slice of your file is verified on the quote. Floor of 3, 5 percent of billable rows, cap of 25. A one-row file is the exception.
Unknowns refunded
If we cannot answer, that share comes back. If the job stops short, the remainder comes back too.

QUESTIONS

What does the check return?
Whether each domain is free to register, its mail provider, and its registrar.
Can I check availability for a whole list?
Yes. parse_available is true when the name is unregistered. One filter turns a name list into a buy list.
Can I drop URLs?
Yes. A full URL resolves to its host, so https://www.stripe.com/about checks stripe.com.
Do you charge for duplicates?
No. The bill counts unique domains. Duplicates, URLs on the same host, and malformed rows are free.
What files can I drop?
Excel, Numbers, CSV, TSV, or a plain text list. A Google Sheets export works too. Spreadsheets convert in the browser when you drop them.
