Evendeals

Fetch discount data directly from the Evendeals API — client-side or server-side.

API mode gives you full control. Call the Evendeals API directly from your frontend or backend — no script tag needed.

Best for: Server-rendered pricing pages, checkout flows, email personalization, mobile apps, or any scenario where you need discount data outside a browser.

When to use the API vs Custom (CSS)

You want to…	Use
Only show discount %, coupon code, country, flag in static text	Custom mode — add CSS classes; no API or extra JS.
Set checkout link to include `?coupon=...` (or append to existing query string)	API — fetch discount, then set `element.href` (or build the URL) in your code.
Show slashed original price and the discounted price on the card	API — parse `discountAmount`, compute new price, update the DOM.
No-code HTML widget (Swipepages, Webflow embed, etc.) with prices + coupon in buttons	Client API — one scoped block (HTML + CSS + fetch + DOM updates) avoids script-tag timing and builder CSS conflicts.

Rule of thumb: Static display → Custom. Dynamic (URLs, price math) → API. See Choosing a display mode for the full guide.

Two endpoints, one API

Endpoint	Auth	Use case
Client-side	None (IP auto-detected)	Browser-based custom integrations
Server-side	API key	Backend, checkout, emails, mobile

Client-side

This is the same endpoint banner.js calls under the hood. You can call it directly for fully custom client-side integrations.

Endpoint

GET https://www.evendeals.com/api/discount?url={pageUrl}

Query parameters

Parameter	Type	Required	Description
`url`	string	Yes	The full URL of the page the visitor is on

The visitor's IP and country are detected automatically from request headers.

Example

const res = await fetch(
  `https://www.evendeals.com/api/discount?url=${encodeURIComponent(window.location.href)}`
);

if (res.status === 200) {
  const data = await res.json();
  if (data.discount) {
    console.log(`${data.discount.countryName}: ${data.discount.discountAmount} off`);
    console.log(`Use code: ${data.discount.couponCode}`);
  }
}

Response (200)

{
  discount: {
    countryCode: string;        // "IN"
    countryName: string;        // "India"
    discountAmount: string;     // "30%"
    couponCode: string;         // "PPP_IN_30"
  };
  settings: {
    blockVpn: boolean;
    autoRefreshEnabled: boolean;
  };
  isVpn: boolean;
  productId: string;
}

Other status codes

Status	Meaning
204	No discount available (no matching product, country, or IP)
422	Invalid parameters

CORS

Returns Access-Control-Allow-Origin: * — callable from any domain.

When to use this vs `banner.js`

If you're already loading banner.js (even with showBanner: false), use Custom mode instead — the script already fetches the data for you. Use the client-side API directly only when you don't want the script tag at all.

Tips (client-side)

No-code widgets: Put one <style>, one wrapper <div class="your-root">, and one <script> that fetches the API and updates only elements inside that wrapper. Scope all CSS under .your-root so the host page’s styles don’t break your layout.
Price math: discountAmount is a string like "30%". Use parseFloat(discountAmount) to compute discounted price and set both the slashed original and the new price in the DOM.
Checkout links: Build the URL as baseUrl + (baseUrl.includes('?') ? '&' : '?') + 'coupon=' + encodeURIComponent(couponCode) so it works on file:// and any base URL.

Server-side

Call from your backend with an API key. You provide the visitor's IP — no browser needed.

Endpoint

GET https://www.evendeals.com/api/discount?ip={visitorIp}&productId={productId}

Authentication

Include your API key in the x-api-key header. Generate keys in Dashboard → Settings → API Keys.

x-api-key: your-api-key-here

Query parameters

Parameter	Type	Required	Description
`ip`	string	Yes	Visitor's IP address
`productId`	string	Yes	Your Evendeals product ID

Examples

cURL

curl "https://www.evendeals.com/api/discount?ip=103.1.168.1&productId=prod_abc123" \
  -H "x-api-key: your-api-key-here"

Node.js / Next.js

const response = await fetch(
  `https://www.evendeals.com/api/discount?ip=${visitorIp}&productId=${productId}`,
  { headers: { "x-api-key": process.env.EVENDEALS_API_KEY! } }
);

if (response.ok) {
  const data = await response.json();
  if (data.discount) {
    // Auto-apply coupon at checkout, show in pricing page, etc.
    console.log(`${data.discount.discountAmount} off: ${data.discount.couponCode}`);
  }
}

Python

import requests

response = requests.get(
    "https://www.evendeals.com/api/discount",
    params={"ip": visitor_ip, "productId": product_id},
    headers={"x-api-key": api_key},
)

if response.ok:
    data = response.json()
    if data.get("discount"):
        print(f"{data['discount']['discountAmount']} off: {data['discount']['couponCode']}")

Response (200)

{
  discount: {
    countryCode: string;
    countryName: string;
    discountAmount: string;
    couponCode: string;
  } | null;
  settings: {
    blockVpn: boolean;
    autoRefreshEnabled: boolean;
  };
  isVpn: boolean;
  productId: string;
}

Error codes

Status	Reason
401	Missing or invalid `x-api-key` header
404	Product not found, or country couldn't be determined from IP
422	Invalid query parameters

Use cases

Server-rendered pricing — show the discounted price before the page loads
