This part of the documentation will show how to make use of our meta API endpoints. Meta API endpoints are special API endpoints that you can call to get some meta information about the resource or entity you would like to request. These endpoints are totally free to use. You can use them to implement a decision system and to save credits with it in cases where a cached resource might be sufficient for your needs. You wouldn't have to create a new crawling task in our engine then to obtain the current or newest version of the resource. It's like a small and free preview of the resource you can get. It also might be that we will extend this endpoints in the future to provide more meta data. You can find a best practice algorithm we recommend here.
