Catsu — Unified Embedding API Client

Catsu provides a single, consistent interface for generating embeddings across 11 providers and 35+ models. Built-in retry logic, cost tracking, and model discovery eliminate the need for provider-specific SDKs.

When to Use This Skill

Use this skill when users want to:

• Generate embeddings from any provider through a unified API
• Compare embedding models across providers (cost, quality, dimensions)
• Add embeddings to a RAG pipeline, search system, or recommendation engine
• Switch between providers without changing application code
• Track token usage and costs across embedding calls
• Use Matryoshka embeddings (reduced dimensions) for storage optimization
