CoreThink Reasoner API Documentation

Welcome to the CoreThink Reasoner API - an advanced platform for Agentic Reasoning that delivers State-of-the-Art (SOTA) accuracy for complex tasks. Our API augments standard large language models with a proprietary, observable reasoning trace, enabling deep, multi-step problem-solving capabilities.

​

Overview

The CoreThink Reasoner API is designed for seamless integration with existing projects using the OpenAI client SDK. By simply changing the base URL, you gain access to advanced reasoning capabilities that excel at planning, tool-use, and multi-step tasks. The API intelligently analyzes your requests and determines the optimal tool-use strategy through its integrated reasoning trace.
