# Language SDKs

To make integrating with the Ziptax Sales Tax API as seamless as possible, we
provide dedicated SDKs for the most widely used programming languages. Each
SDK is designed to offer idiomatic usage patterns, built-in authentication
helpers, streamlined request/response handling, and first-class support for
our full tax-calculation, jurisdiction, and lookup workflows.

Whether you're building a high-throughput backend service, a serverless
function, or a lightweight script, these libraries help you implement
accurate sales tax logic with minimal effort.

## Available SDKs

#### [Go SDK](go-sdk)

Fast, type-safe client for high-performance backend services, microservices,
and concurrent pipelines.

#### [Python SDK](python-sdk)

Simple, intuitive client for scripts, data pipelines, Lambda, FastAPI, and
Django applications.

#### [Node SDK](node-sdk)

JavaScript / TypeScript client for Node.js backends, edge functions, and
frontend server code.
