# SpotLens > Cross-exchange crypto spot price analysis for traders: one live fair USD price per coin, the spread between > exchanges and AI trade plans. Not financial advice. ## What it offers - Fair price: one reference USD price per coin, weighted by volume and exchange reliability, so a thin or stale exchange cannot move it. - Exchange spread: how far apart exchanges price the same coin, and each exchange's premium or discount to the fair price, also as a chart overlay. - Exchange ratings: fees, order rules and a reliability rating for every exchange. - AI trading assistant: built on OpenAI GPT technology (the model family behind ChatGPT). It reads the live market for a coin and returns buy, sell or hold with entry, target, stop and a confidence score; plans are saved per coin in a free account. Not financial advice. - Live data from leading spot exchanges; trade, source and LLM servers in the US, Canada, Europe, Dubai and Australia. - Coverage: centralized exchanges with at least $1B of 24h volume (checked hourly against CoinGecko); on each, coins with at least $1M of 24h volume. Halted books, look-alike tokens, mirrored books and prices that stop updating are excluded. - Clean universe: USD and USD-stablecoin spot pairs of established coins; no derivatives, no stablecoins as assets. ## Pages - [Home](https://spotlens.cloud/): venue check, top coins, AI trading assistant, exchanges, FAQ - [Live markets](https://spotlens.cloud/markets): live fair price, spread and volume for the leading coins, with an exchange comparison chart
