SMS verification API

Two APIs share one key: a REST API with JSON, and the SMS activation format that many tools already use. Create the key on the API key page of the console; it is shown once. Limit: 300 requests per minute per key. Each order has a 20 minute code window, the same as in the console.

# REST API (JSON)
curl https://virtualsns.com/api/v1/balance -H "Authorization: Bearer YOUR_KEY"

# SMS activation format
curl "https://virtualsns.com/stubs/handler_api.php?api_key=YOUR_KEY&action=getBalance"

Service codes are the names in our service page addresses, for example kakaotalk, line, wechat, zalo, naver, shopee and whatsapp. Country codes are ISO codes in lower case: kr, jp, id, ph, vn, th, us. GET /services and GET /countries return the full lists.

1. Order a number with the service and the country. Save the id.
2. Enter the number in the app and ask it to send the SMS.
3. Read the order every 4 seconds until a code is there.
4. Need one more SMS? Ask for another code, then read again. Done: finish the order.
5. No code? Cancel for a full refund. Without a call, the refund happens by itself when the window ends.

Python

import os, time, requests

API = "https://virtualsns.com/api/v1"
H = {"Authorization": f"Bearer {os.environ['VIRTUALSNS_KEY']}"}

order = requests.post(f"{API}/orders", headers=H,
    data={"service": "kakaotalk", "country": "kr"}).json()["order"]
print("Use this number:", order["phone"])

while True:
    o = requests.get(f"{API}/orders/{order['id']}", headers=H).json()["order"]
    if o["code"] or o["status"] in ("refunded", "canceled"):
        break
    time.sleep(4)
print("Code:", o["code"])

Node.js

const API = "https://virtualsns.com/api/v1";
const H = { Authorization: `Bearer ${process.env.VIRTUALSNS_KEY}` };

const { order } = await fetch(`${API}/orders`, {
  method: "POST", headers: H,
  body: new URLSearchParams({ service: "line", country: "jp" }),
}).then((r) => r.json());
console.log("Use this number:", order.phone);

let o = order;
while (!o.code && !["refunded", "canceled"].includes(o.status)) {
  await new Promise((r) => setTimeout(r, 4000));
  ({ order: o } = await fetch(`${API}/orders/${order.id}`, { headers: H }).then((r) => r.json()));
}
console.log("Code:", o.code);
