Blocktrail - Good to receive payments, but take many fees (For a transaction of 5$ i lose 10$ !)
How is that even possible ? Seems irrelevant logically.You should probably report the issue to their support.
Can someone suggest me any trusted alternative solution please ?
For that,you need to tell us a few things about your project
-How many transactions you send/receive on daily basis ?
-Are you taking the transaction fees from your customers or paying them yourself ?
-Is that big/medium/small sized project ?
If you think you need not depend on an API given their restrictions,start writing code from scratch or fork one of the open source repos.
