SDKs

CashXChain is API-first. Official SDKs will be released for common backend environments as the platform matures.

Planned SDKs​

  • TypeScript / Node.js.
  • Python.
  • Go.
  • Java / Kotlin.
  • PHP for platform and ERP integrations.

Current recommendation​

Until an official SDK is available for your language, use HTTPS directly with a mature HTTP client. CashXChain uses simple JSON request and response bodies.

TypeScript example​

const response = await fetch('https://api.sandbox.cashxchain.com/v1/fx/quotes', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.CXC_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    source_currency: 'EUR',
    target_currency: 'USD',
    source_amount: '1000.00',
  }),
});

if (!response.ok) {
  throw new Error(await response.text());
}

const quote = await response.json();

Python example​

import os
import requests

resp = requests.post(
    'https://api.sandbox.cashxchain.com/v1/fx/quotes',
    headers={
        'Authorization': f"Bearer {os.environ['CXC_API_KEY']}",
        'Content-Type': 'application/json',
    },
    json={
        'source_currency': 'EUR',
        'target_currency': 'USD',
        'source_amount': '1000.00',
    },
    timeout=30,
)
resp.raise_for_status()
quote = resp.json()

SDK requirements​

Any official SDK will support:

  • Request signing or bearer authentication.
  • Idempotency key helpers.
  • Pagination helpers.
  • Webhook signature verification.
  • Typed errors.
  • Sandbox and production environment separation.
