# Introduction **Current Version: 1.8** Welcome to the RealTrex API. This service provides access to broker price opinions through specialized endpoints. All endpoints target `api.realtrex.com`. ## API Versioning The RealTrex API follows semantic versioning to ensure stability and backward compatibility for our clients: ### Minor Releases (Non-Breaking Changes) Minor version updates (e.g., 1.1, 1.2, 1.3, 1.4) **only add new functionality** and do not remove existing features. These updates are designed to be fully backward compatible, meaning your existing integrations will continue to work without any changes. ### Major Releases (Breaking Changes) When a major version update is released (e.g., 2.0), it may include breaking changes such as removed or significantly modified endpoints. However, we ensure continuity by: * Keeping the previous major version available and supported for an extended period * Providing complete documentation for the previous major version * Giving advance notice before any major version changes This approach ensures your applications remain stable and functional, regardless of which API version you're using. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
