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 value (or series of RSI values) for the requested symbol, computed over the specified interval and time period. Typical output includes the symbol, indicator name, timestamps, and RSI numeric values indicating momentum strength (values above 70 suggest overbought, below 30 suggest oversold).
Example use cases

“What's the current RSI for TSLA on the daily chart using a 14-period time period? I'm trying to gauge momentum ahead of their earnings report.”
Forex technical signal for algo strategy

Endpoint
GEThttps://tw3lvtrexdata.vercel.app/api/rsi/%7Bsymbol%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need RSI specifically as a technical indicator for stocks, forex, or crypto. Prefer it over general price endpoints when you need momentum/overbought/oversold signals for trading decisions, backtesting, or algorithmic strategies. It is well-suited for agents that need a single computed indicator value rather than raw OHLCV price data.
