## AI overview

This article describes how trivago used GraphQL Mesh to unify fragmented internal APIs into a gateway for administration, CRUD operations, reporting, and data exploration. It covers the architecture, implementation challenges encountered over six years in production, and possible future uses involving AI agents.

## Source excerpt

Most GraphQL Gateway discussions focus on public-facing APIs and multi-client architectures. This article explores a different axis--using GraphQL Mesh to stitch internal services into a unified gateway powering admin tooling. We share implementation details, honest challenges from six years in production, and a forward-looking perspective on how AI agents could leverage the unified graph.
