# Introduction

> Lumin APIs let you build document workflows — eSignatures, templates, and automation — directly into your application.

All API endpoints use standard HTTP methods, return JSON responses (except documented file downloads), and follow predictable resource-oriented URL patterns.

## Base URLs

| Environment | Base URL                      |
| ----------- | ----------------------------- |
| Production  | `https://api.luminpdf.com/v1` |
