A method for providing a desired portion of a data object document is disclosed. The method comprises receiving, from a client device, an Application Program Interface (API) request for a data object document, where the API request includes a parameter identifying the desired portion of the data object document, and the desired portion is less than all of the data object document. The method continues with transmitting the API request for the data object document to an origin server, and receiving an API response from the origin server that includes the data object document including more than the desired portion of the data object document. The method further includes automatically selecting, from the received data object document, the desired portion of the data object document based on the parameter, and transmitting, to the client device, the desired portion instead of all of the data object document.
