Is there database of orphaned blocks? Is there database of orphaned blocks?

https://blockchain.info/orphaned-blocks does not work right now

Does anybody keep them?

Also I am looking for those transactions which were not included in blocks (non-standard, double-spends, not enough fees, etc)
Do you need a user interface or to find them via API? We do not have UI at the moment for this (we will very soon) but you can definitely use our REST API to get them.

If the API is what you need then you can just use the following API call to filter ORPHANED blocks only. 


  https://api.biteasy.com/blockchain/v1/blocks?type=ORPHANED


If the transactions weren't included in the main chain then they will either be DEAD or PENDING and you can fetch them with the following API call:


  https://api.biteasy.com/blockchain/v1/transactions?confidence=DEAD


and 


  https://api.biteasy.com/blockchain/v1/transactions?confidence=PENDING


Check out the link to our documentation and also you can use our testing tool which you can find here https://www.biteasy.com/developers/sandbox
