You can see in the endpoints if you type a country without camelCase there is an 500 error, same for nsfw if you type false without camelCase. But it didn’t take the search, like your search is completely false. With manga from every country if you put your search in camelCase but without error. Maybe I’ve misunderstood smth.

Sorry for yesterday will on maintance, but you can try again, the search key should be use title and alternative title, you can try again, Thank You
