Provides semantic search across a curated catalog of free public APIs using embedding-based natural language queries to help developers discover APIs by use case, retrieve detailed metadata including authentication and CORS requirements, and match requirements to available capabilities.
Computed from public signals only — stars, package downloads and how many registries list it. It measures how established a project is, not whether it is safe or right for you.
