Introduction

GoGoDuk is a developer-first Vietnam map platform: geocoding, address search, POI search, admin boundaries, and reverse-geocoding. Simple REST + JSON, generous free tier, no SDK required.

What you can build

• Address autocomplete inputs in apps and websites.
• Reverse-lookup of GPS coordinates → ward / district / province.
• POI search around a point, by category, or inside a bounding box.
• Map-based dashboards backed by clean Vietnamese address data.

Three steps to your first call

1. Sign up and grab an API key from the dashboard.
2. Pass it as X-API-Key on every request.
3. Hit any endpoint — start with /v1/suggest.

Where to next

• Quickstart — first call in under a minute.
• Authentication — how API keys work.
• Rate limits — per-plan quotas + 429 behavior.
• Errors — the consistent error format.
