# API Documentation

This page provides links to the detailed API documentation for all components of the QuantileFlow package.

## Sketch Algorithms

QuantileFlow provides three main algorithms for quantile estimation:

- [DDSketch](api/ddsketch.md) - Distributed and Deterministic Sketch with configurable relative error
- [MomentSketch](api/momentsketch.md) - Moment-based quantile sketch using maximum entropy optimization
- [HDRHistogram](api/hdrhistogram.md) - High Dynamic Range Histogram for tracking values across multiple orders of magnitude

## API Reference

For a comprehensive list of all classes and methods, see the [API Reference](api/index.md).
