Every developer’s journey with ZBD starts in the sandbox. It’s your risk-free playground where you can test payments, break things, and perfect your integration before touching real money.
Default Environment: All new projects start as sandbox projects. This protects you from accidentally spending real Bitcoin while learning the platform.

​
What Makes Sandbox Special

Fake Bitcoin

10,000 free satoshis to start, top up anytime

Test Users

Pre-created users with wallets for end-to-end testing

​
Visual Indicators

Sandbox projects are clearly marked to prevent confusion:
Sandbox Project Created

Sandbox projects show clear labeling in the dashboard

Look for:
  • 🧪 “Sandbox” label on project cards
  • 🎮 Test Bitcoin balance (not real money!)
  • 👥 Test Users tab only in sandbox
  • 🔑 Sandbox API endpoints in documentation

Sandbox API Endpoints

Sandbox uses separate endpoints to ensure you never accidentally mix test and production: 
Base URL: https://sandbox.api.zebedee.io

Example endpoints:
- /v0/gamertag/send
Currently Limited: Only the Send to Gamertag API is available in sandbox. More endpoints coming soon. For full API testing, complete verification for production access.

​
Testing Payments in Sandbox

Let’s send your first test payment:

​
1. Get Your Sandbox API Key

  -H "apikey: YOUR_SANDBOX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "gamertag": "SandboxUser1#7823",
