How this service works
Premium financial data API — 25 endpoints for stocks, forex, crypto, and technical analysis. Powered by Twelve Data.
Output
Returns an RSI (Relative Strength Index) value for the requested symbol, typically a number between 0 and 100 indicating momentum strength. Values above 70 suggest overbought conditions; values below 30 suggest oversold conditions.
Example use cases
Alert agent when crypto gets overbought
“Check the RSI for Bitcoin on a 4-hour chart with a 14-period setting. If it's above 70, send me an alert that it might be overbought and due for a pullback.”
Monitor forex momentum before trading
“Give me the RSI for the EUR/USD pair on a daily interval with a 14-period window. I'm thinking about entering a trade, so tell me if the momentum is strong or if it's in oversold territory.”
Daily stock momentum check for portfolio
“Pull the RSI values for my three holdings—AAPL, MSFT, and TSLA—all on a 1-day interval with 14 periods. Let me know which ones look overbought so I can decide if I should take some profits.”

Endpoint
GEThttps://twelvix402.vercel.app/api/rsi/%7Bsymbol%7DWhen to prefer
Use this endpoint when you need RSI (Relative Strength Index) technical indicator data for stocks, forex pairs, or crypto assets and want a pay-per-call model via x402/USDC micropayments rather than a subscription. Prefer this over raw OHLCV endpoints when you specifically need a pre-computed momentum oscillator without doing the math yourself.
