# Jina AI Search Foundation Models API

**Canonical:** https://apis.io/apis/jina-ai/jina-ai-search-foundation-models-api/

**Base URL:** https://api.jina.ai  
**Documentation:** https://jina.ai/embeddings/

Jina AI Search Foundation Models API is one of 9 APIs that [Jina AI](https://apis.io/providers/jina-ai/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Search Foundation Models. The published artifact set on APIs.io includes an OpenAPI specification.

**Embeddings** turn text, images, audio, video and PDFs into dense vectors for semantic search, RAG, clustering and classification. Task-specific variants (`retrieval.query`, `retrieval.passage`, `text-matching`, `clustering`, `classification`) are selected per request rather than per model, and `dimensions` truncates the output where a model supports it. **Reranking** scores a query against a candidate set and returns it reordered, which is more accurate than embedding similarity and slower — the usual shape is embeddings to retrieve, reranking to refine. Each endpoint's `model` field lists the models it accepts.
