Thank you for your reply~
I add “disable_test_connection=true” but looks the same speed~
another question: why some response body have “possible_typo”:[]?

Hi!

The speed of the API depends on many things. Many results are cached, and will return a response much faster. If the domain is not cached, and unknown, there are multiple checks to verify that it’s either valid, invalid, or a disposable domain.

In general, most results should have an average of about ~0.5 sec, but it really depends on “the uniquness” of the domains.

You can disable some of the more lengthy tests by adding the parameter “disable_test_connection=true”. It will do most of the lookups, and still give a really good result.

Thanks!
