About

SpreadRadar started from a simple problem: to see where crypto is cheaper to buy or better to sell, you had to keep a dozen tabs open and compare numbers by hand. We pulled that data into one place and present it so the difference is obvious at a glance.

What the service does

We query the public interfaces of major crypto exchanges and the open APIs of central banks, normalise the numbers and compute the difference between venues. The site shows P2P rates, perpetual futures funding rates, spot market spreads and official FX rates next to the real dollar price in USDT.

Where the data comes from

Sources are the public data of Binance, Bybit, OKX, MEXC, KuCoin, Bitget, Gate, HTX and BingX, plus the National Bank of Ukraine, the European Central Bank, Monobank and PrivatBank. These are the same figures any visitor sees on the exchange website — simply collected together and recalculated.

Data refreshes continuously: P2P and spot every 30 seconds, funding rates once a minute, bank rates several times an hour. If one exchange stops responding the rest keep working, and the status line shows whose data is missing.

Principles

• No sign-up. Every tool opens straight away, no account needed.
• No access to your accounts. We never ask for API keys, passwords or exchange access, and we never handle crypto on anyone's behalf.
• No hidden terms. The service is free, with no paid tiers or usage limits.
• Honest numbers. Next to every price we show the ad limits and available size, because the best price is often available only for a small amount.

Important disclaimer

SpreadRadar is an information service, not a financial adviser. We give no investment recommendations and cannot guarantee that a displayed price difference will still be available when you trade. P2P and spot quotes change by the minute, some offers disappear within seconds, and every venue has its own fees, limits and withdrawal rules. Always check the terms on the exchange before trading. All decisions and risks remain yours.
