Overview

Nexchange is an automated cryptocurrency exchange service API that lets you programmatically create and track currency swap orders. It supports a wide range of trading pairs and requires no authentication for basic queries. This makes it a simple and accessible API for beginners exploring crypto exchange integrations.

Beginner Tip

No API key is needed to use Nexchange for basic order and price queries, so you can test it directly from the command line. Start by exploring available trading pairs using the /api/v1/pairs/ endpoint.
