Embeddings & Search APIs
Embeddings and search APIs transform text, images, and other data into dense vector representations that power semantic search, recommendation systems, and retrieval-augmented generation workflows. An embeddings API converts your content into high-dimensional vectors that capture meaning, enabling similarity matching that goes far beyond traditional keyword search.
Vector search APIs provide the infrastructure for storing, indexing, and querying millions of embeddings with sub-millisecond latency. Combined with embedding models from providers like OpenAI, Cohere, and open-source alternatives, these services form the foundation of modern AI-powered search experiences that understand user intent rather than just matching keywords.
Use cases span from semantic document search and duplicate detection to product recommendations, question-answering systems, and RAG pipelines that ground large language model responses in your proprietary data. Compare embeddings and vector search providers based on model quality, index performance, scalability, and cost.
