BLOX Developer Documentation

Build MYRC-native applications with BLOX APIs. Our APIs allow you to integrate fiat-to-MYRC and MYRC-to-fiat functionality directly into your platform.

API Products

Quick Start

1. Get API Credentials

Contact the BLOX team to obtain your API credentials:

• Sandbox Keys - For development and testing
• Production Keys - For live applications

API keys are managed through the Business Portal .

2. Understand Authentication

All API requests require:

• API Key - Via blox-api-key header
• Request Signature - RFC 9421 HTTP Message Signature for POST/PUT/PATCH/DELETE requests

curl https://api.blox.my/v1/health \
  -H "blox-api-key: YOUR_API_KEY"

{
  "success": true,
  "message": "API key is valid",
  "account": {
    "id": "acc_...",
    "name": "Your Business Name",
    "type": "BUSINESS",
