Embedding Models
FreeGET /api/embeddingsThe /api/embeddings endpoint returns the curated catalog of production-ready embedding and reranker models. Each entry includes provider, dimensions (null for rerankers), max input tokens, $/1M tokens, MTEB average score, multilingual flag, license, and a one-line note. Filter with ?type=embedding or ?type=reranker.
When to use this endpoint
When your agent needs to pick or compare embeddings for a RAG pipeline. The /api/models endpoint covers chat/completion models; this is the missing peer for embeddings + rerankers.

How current is the embedding catalog?
Editorial. Refreshed on redeploy when providers ship a new version or change pricing. Embedding-model pricing changes rarely (months, not days), so a daily cron does not match the data.
Why is rerank-v3.5 listed at $0?
Because Cohere prices rerank by search (each search = up to 100 documents reranked), not by token. The pricingNote field on each entry has the actual pricing model.
