Which Approach is Right for me?

Accurate Append’s APIs are for developers who want to integrate Accurate Append’s data processing capabilities directly into their application(s) in a real-time manner. It specializes on enhancing or appending a single record of data per use. While the end user of your applications do not require technical knowledge, this approach requires developers to program against our technology and isn't intended for direct use.

More information about Real-Time API

Accurate Append's Batch Processing utilizes the same data and the same logic as our API. Batch processing can be a good option if you want to process a large number of requests or don't want to invest developer resources in creating the infrastructure needed to parallelize API calls. It is also appropriate for business processes that involve direct human interaction. However, our Batch Processing solutions are still fully capable of being integrated with your applications and technology solutions. In all cases, Batch Processing will occur on our system and does not operate in a real-time manner.
