# Platform SDK APIs Documentation

This section documents the usage of the 3 main set of APIs the Platform SDK exposes - Data APIs, Log APIs and Metric APIs.

Data APIs

Data APIs provide functions for a Block developer to push and read data from the data queue for a Block.

Log APIs

Log APIs provide functions for a Block developer to publish logs to the log server that provides debug information when the Block executes.

Metric APIs

Metric APIs provide functions for a Block developer to publish various metrics from their Block to the metric server. These metrics can then be visualized in the Pipeline Run Results interface as various charts and graphs like line chart, bar graph, confusion matrix and such.
