API requests links but not getting all of them

Hello, when i request API with /count, i get 214k links.
But when i request 25 per 25 with a loop on Talend and the last parameter, i get 200299 links exactly, and it finishes by the right link (the last one of them all).
I do an orderBy updatedAt, and sometimes i notice that some links are bypassed, when for example they have the same updateDate exactly.

Do you have some solutions ?
Thanks,
Nathan
