Environments & Supported Chains
This page covers API base URLs and the blockchain networks returned by GET /v1/wallet/networks (active networks and active MYRC tokens only). Always prefer that endpoint over hard-coding IDs.
API Environments
| Environment | Base URL |
|---|---|
| Sandbox | https://api.sandbox.blox.my |
| Production | https://api.blox.my |
Hostnames: production https://api.blox.my, sandbox https://api.sandbox.blox.my. There is one merchant surface — Wallet, Onramp and Payout all live under /v1.
Quick health check
curl "https://api.sandbox.blox.my/v1/health" \
-H "blox-api-key: $BLOX_API_KEY"{
"success": true,
"message": "API key is valid",
"account": {
"id": "…",
"name": "Your Business Name",
"type": "BUSINESS",
"status": "ACTIVE"
}
}Tip: Never commit production keys. Use a secret manager or CI/CD secrets.
