: Logging into the game daily gives you a chance to receive a coupon for up to 75% off your next Platinum purchase (PC) or a bonus on console purchases.
If you're interested in obtaining more Platinum for in-game transactions, you can do so through the in-game market or on the Warframe website. This is the safest and most straightforward method to acquire Platinum.
If you’re looking to build a legitimate tool for Warframe — such as a price-check assistant for trading, a riven calculator, or a drop tracker — I’d be glad to help you design that instead. Just let me know what kind of feature you actually want to create.
