IDRX Transaction API

openapi: 3.1.0
info:
  title: IDRX Onboarding Transaction API
  version: '1.0'
  description: IDRX is a stablecoin pegged 1:1 to the Indonesian Rupiah (IDR). This REST API lets business (organization) accounts onboard users, manage bank accounts, and process mint (fiat IDR -> IDRX / USDT on-chain), redeem (IDRX -> fiat IDR to a bank account), and bridge (move IDRX across supported EVM/Solana chains) transactions, plus query rates, fees, bank methods, and transaction history. All requests are authenticated with an API key plus an HMAC-SHA256 request signature. A custom `User-Agent` header is required (generic agents are blocked at the edge with HTTP 403 / Cloudflare 1010).
