# Introduction

Welcome to the Sequestor API documentation. This API suite offers our most advanced carbon project data capabilities, including:

* Project filtering with standardised parameters, natural language, and advanced metadata.
* Intelligent document search with natural language.
* Comprehensive metadata for carbon projects, including both standard metadata and bespoke metadata extracted and processed from project documentation.
* Project comparisons / batch processing across metadata or document content. 

We currently offer full support for all projects in the Verra registry and limited capabilities for projects under Gold Standard and Puro.Earth.
