# Semantic Search API

A production-ready semantic search API built entirely on Cloudflare's free-tier infrastructure, with OpenAPI documentation and separate reader and writer API keys.

Semantic Search API is a document search service deployable to Cloudflare Workers, using a Cloudflare Vectorize index for vector storage and documented with a full OpenAPI specification and Swagger UI. It exposes endpoints to create, update, retrieve, delete and semantically search documents, each carrying arbitrary metadata.

Access is split between writer keys, required for endpoints that create or delete documents, and reader keys, which may only call read and search endpoints; both key types support multiple comma- or newline-separated values so several keys of the same type can be issued at once, letting writer keys stay in trusted server or CI environments while reader keys are safe to embed in public clients. TypeScript, deployed with a one-click option or manually through Wrangler.
