# Aggregator Investment API For corporate entities offering digital services with interest in providing ending services to their customers or staffs, this section is a guide on the stepwise journey in accomplishing your corporate lending goal. We provide REST APIs, and recommend testing our APIs using a rest client tool such as [postman](https://www.postman.com/). This needs to be done before going ahead with the integration using your preferred programming language. {% content-ref url="/pages/y0YFXQQK5ZJBHu2yccMu" %} [Aggregator Investment](/aggregator-investment-api-integration/aggregator-investment-api-for-metal.md) {% endcontent-ref %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
