Node SDK

The Node SDK provides a first-class JavaScript / TypeScript client for the Ziptax API, with idiomatic patterns for Node.js backends, edge functions, and server-rendered frontends. It includes built-in authentication, automatic retries, TypeScript type definitions, and helpers for the full tax-calculation and jurisdiction-lookup workflow. It ships both CommonJS and ES Module builds and requires Node.js 18 or later.
