# Data layer

The 0x\_nodes data layer is a set of analytic tools that provide
 insights into platform performance statistics, market opportunities,
 and the health of 0x\_nodes investment strategies.

The 0x\_nodes autopooling engine draws on data from an internally developed tool,
 “deXcraper”, which continuously monitors the performance of 0x\_nodes strategies
 and compares underlying liquidity pool performance to other candidate pools
 across DEX platforms. deXcraper will soon be released as open-source software
 and has been developed with strong 0x\_nodes community engagement.

0x\_nodes provides open access to its subgraph API endpoints to provide platform
 statistics, such as strategy performance, user positions, and in-depth accounting
 information. Other automated tools include Dune Analytics and Discord bots that
 provide on-demand platform performance reports to the 0x\_nodes community.
