Example use cases

Overbought/oversold stock screening

“Check the 14-period RSI for NVDA on the daily timeframe using closing prices — I want to know if it's overbought above 70 or oversold below 30 right now.”

Intraday momentum signal for algo trading

“Fetch the 9-period RSI for SPY on 5-minute intervals for October 2024 using close prices so I can backtest a short-term momentum strategy.”

Weekly RSI for long-term position sizing

“Get the 21-period RSI for MSFT on the weekly chart using closing prices — I'm trying to decide whether to add to my long-term position.”

When to prefer

Choose this endpoint when you need RSI technical indicator data for a specific stock symbol with pay-per-call pricing via x402 micropayments — ideal for agents that make infrequent or variable-frequency calls and want to avoid subscription overhead. Prefer this over a direct Alpha Vantage subscription when operating in an autonomous agent context with on-chain USDC payment capability.

Side effects

Invalid or unrecognized ticker symbol returns empty or error data
Unsupported interval string causes a bad request response
time_period value too small or too large may return incomplete RSI series
Missing required fields (symbol, interval) result in validation errors
Payment failure via x402 protocol blocks the request entirely
Rate limiting or Alpha Vantage API quota exhaustion returns an error
