Welcome to the Codex API docs.

This API provides accurate, enriched, real-time and historical blockchain data. You can retrieve enhanced data, including USD pricing, real-time aggregates and much more.

Codex was previously named the Defined API, so you may come across references to Defined while we transition to our new name.

Here are a few notable groups of endpoints to get you started:

List all networks supported on Codex or check on a network's status.

Get metadata, prices, events, detailed stats, or search and filter through the millions of tokens listed on Codex.

Get collection/asset metadata, events, detailed stats, or search through the over one billion NFTs listed on Codex.

Get alerted when anything happens on-chain. (Available for enterprise users only)

Handy when you want to see the detailed set of GraphQL types and fields that are available for an endpoint you're building with.
