Case Study: OpenRouter powers model-agnostic web search with Exa's semantic search

OpenRouter - Customer Case Study

OpenRouter, a major model-agnostic AI routing layer, faced the challenge of integrating live web search functionality across its platform. Their hundreds of thousands of users needed answers with fresh sources, but building a solution in-house required state-of-the-art search, a unified interface, no extra infrastructure for customers, predictable costs, and a production rollout in under a week.

Exa implemented its semantic search technology as the sole search engine powering OpenRouter's new web plugin. This provided LLM-ready retrieval for all 400+ models on the platform with a simple integration. The solution was deployed in under a month and has since powered over 2.36 million queries, grounding AI responses in real-world data for OpenRouter's users.
