Getting Started with QYX20

Welcome to the QYX20 developer documentation. QYX20 exposes a unified REST API that gives you programmatic access to every module of the financial OS: identity, accounts, wallets, assets, payments, settlement, compliance, and AI agents.

Before You Begin

• Create a QYX20 account at app.qyx20.com/create-account
• Generate an API key from the Developer module in the sidebar
• All requests must use HTTPS — HTTP requests are rejected
• API keys carry full access — store them in a secret manager, never in code

Base URL

Production:  https://api.qyx20.com/v1
Sandbox:     https://sandbox.qyx20.com/v1

Request Format

All requests should include the following headers:

Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
X-Idempotency-Key: <uuid>  // Required for POST/PATCH mutations

Response Envelope

All API responses follow a standard envelope format:

{
  "ok": true,
  "data": { ... },
  "meta": {
    "request_id": "req_01HXYZ...",
    "timestamp": "2026-08-02T00:00:00Z",
    "version": "v1"
  }
}
