# Overview

## What is GRAPI?

The M-Files API Suite **GRAPI** (GraphQL API) is a modern, high-performance GraphQL service built on .NET 8.0 and HotChocolate that provides a flexible and powerful interface to M-Files vault data.

GRAPI automatically generates strongly-typed GraphQL schemas from your M-Files vault structure, enabling advanced querying capabilities with comprehensive filtering, intelligent sorting, and optimized nested object resolution.

## Key Capabilities

- **Multi-Vault Support**: Query multiple M-Files vaults through a single GraphQL endpoint with vault-specific namespacing
- **Advanced Filtering**: Comprehensive where clause support with nested conditions on all object properties
- **Intelligent Lookup Resolution**: Automatic nested object resolution with smart depth calculation
- **Real-time Data Access**: Direct integration with M-Files via high-performance TRAPI service
- **Type Safety**: Strongly-typed GraphQL schema with proper scalar types and validation
- **Hot Schema Refresh**: Runtime schema updates without service restart
- **Rich Query Capabilities**: Support for complex filtering, sorting, and field selection
- **Performance Optimized**: Intelligent lookup depth calculation, query optimization, and response caching
