When to Use

• Technical analysis -- User asks for RSI, MACD, Bollinger Bands, or trend direction for a token.
• Arbitrage hunting -- User wants to find price discrepancies across DEXes for profitable trades.
• Yield farming -- User asks for the best DeFi yields for a specific asset or chain.
• Whale tracking -- User wants to monitor large wallet movements or see top holders.
• Token safety -- User asks whether a token is safe, wants honeypot detection, or contract audit.
• Strategy testing -- User wants to backtest a trading strategy against historical data.
• Pool analysis -- User wants to find top liquidity pools or analyze pool metrics.
• Gas optimization -- User needs gas prices to time transactions for lower costs.
• Funding rates -- User wants to see perpetual funding rates or funding rate arbitrage.
• Market overview -- User asks for overall market conditions, fear/greed, or correlation data.

Best Practices

• Start with quick checks -- Use /token-audit/quick and /technical-analysis/summary for fast screening before committing to deeper (and more expensive) analysis.
• Combine technical and on-chain data -- Use technical analysis alongside whale monitoring and volume analysis for more informed trading decisions.
• Filter yields by TVL -- Always set a min_tvl when searching for yields to avoid low-liquidity pools that may carry higher risk.
• Set minimum profit for arbitrage -- Use min_profit_pct to filter out marginal opportunities that would not cover gas costs.
• Use gas endpoint before trading -- Check gas prices before executing swaps or arbitrage to ensure profitability.
• Backtest before deploying -- Use the backtesting endpoint to validate strategies on historical data before risking real capital.
