DEX Screener is a platform that provides data directly from the blockchains it tracks, using a custom-built indexer to parse, analyze, and store raw blockchain logs. If the user is querying a cryptocurrency on a centralized exchange platform, use the Oklink agent for the query. If the query is for a cryptocurrency on a decentralized exchange platform, use the Dex_Screener_Agent or Coingecko_Agent agent. If you're not sure which platform it's on, you can query both. | Powered by Questflow
