Overview - JustRouting Docs

JustRouting SDK

Official client libraries for every JustRouting API family — Directions, Distance Matrix, Map Matching, Trip, Nearest, Geocode, and Fleet Optimization. All SDKs are open source (MIT) and zero third-party dependencies, so they run on Lambda, Cloudflare Workers, and edge environments as-is, with typed errors and built-in 429 retries.

Language	Page	Install	Source
Python 3.9+	Python Client	`pip install justrouting`	py-client
JavaScript / TypeScript	JavaScript Client	`npm install @justrouting/client`	js-client
Go	Go Client	`go get github.com/justrouting/go-client`	go-client

Shared conventions

new Client(apiKey) attaches Authorization: Bearer to every request automatically
Coordinates always use [lng, lat] order
Unreachable matrix cells come back as null (not 0) — you decide how to handle them
Zero dependencies means they run on Lambda, Cloudflare Workers, and edge environments as-is

No SDK? No problem

The SDKs are thin wrappers over plain REST. You can always call the HTTP endpoints directly — every API Reference page has curl examples.
