5The Batch API lets you process large volumes of requests asynchronously with reduced pricing and higher rate limits. For pricing details, see [Batch API Pricing](/developers/pricing#batch-api-pricing). If you need lower latency on real-time requests instead, see [Priority Processing](/developers/advanced-api-usage/priority-processing).5The Batch API lets you process large volumes of requests asynchronously with reduced pricing and higher rate limits.
