✨Introduction

Nansen API offers programmatic access to high-quality onchain data and advanced blockchain analytics across numerous networks. The API aims to equip users with the necessary data to gain a competitive edge, identify opportunities, perform due diligence, and make informed decisions within the dynamic crypto market. It effectively translates the complexity of raw blockchain data into actionable intelligence, accessible through a structured API interface.

Key Capabilities

• Proprietary Data Labeling: Nansen applies unique, human-readable labels to hundreds of millions of blockchain addresses. These labels identify specific entities such as exchanges, funds, market makers, notable individual investors that allows users to understand who is behind onchain activities, providing crucial context that raw, pseudonymous data lacks. Accessing this labelled data via the API is a core component of Nansen's offering.

• Unique Datasets and Insights: The API provides access to data points and analytics not readily available elsewhere, such as Smart Money analytics.

• Comprehensive Multi-Chain Coverage: The API consolidates data from multiple blockchain networks, allowing users to track assets and activities across different ecosystems through a single integration point.

These features collectively enable the API to deliver not just data, but contextualized intelligence, transforming raw onchain events into a clearer picture of market dynamics and participant behavior.

Available Plans

Access to all API endpoints is available via the Professional Plan. You can request API access if you're on a 6-month or 12 month Professional Plan or sign up to one of the plans to get access to the API.
