The Cohere Datasets API provides endpoints for uploading, managing, and retrieving datasets used with other Cohere services such as fine-tuning and embed jobs. Developers can create datasets from files, list existing datasets, retrieve dataset metadata, and delete datasets they no longer need. The API supports various data formats and validates uploaded data against expected schemas.
Every API here is available over the APIs.io API and to AI agents over MCP.
One button, every client — Claude, Cursor, VS Code and the rest.

title: Cohere Chat Datasets API
description: The Cohere Chat API enables developers to integrate large language model text generation capabilities into their applications through a conversational interface. It supports multi-turn conversations, tool use with JSON schema definitions, retrieval-augmented generation, and streaming responses. The API is available via the v2 endpoint and works with Cohere's Command family of models.
