How this service works
Relative strength index (RSI) for an asset slug.
Output
Returns the RSI (Relative Strength Index) value for the specified cryptocurrency asset slug. RSI is a momentum oscillator ranging from 0 to 100, where values above 70 typically indicate overbought conditions and values below 30 indicate oversold conditions. The response includes the computed RSI figure and likely associated metadata such as the asset slug and timestamp.
Example use cases
Crypto overbought/oversold check
“Can you pull the RSI for Ethereum right now and tell me whether it's in overbought or oversold territory?”
Trading signal for altcoin
“I'm considering buying Solana — what does CoinCap's RSI say about it? Is the momentum favorable?”
Automated portfolio rebalance trigger
“Check the RSI for Cardano and let me know if it's dropped below 30, which would signal an oversold condition I want to act on.”

Endpoint
GEThttps://rest.coincap.io/v3/agentFriendly/ta/bitcoin/rsiWhen to prefer
Choose this endpoint when you need a pre-computed RSI technical indicator for a specific cryptocurrency without doing your own time-series math. It is ideal for trading bots, portfolio monitoring agents, or financial dashboards that need momentum signals quickly. Prefer this over raw price history endpoints when you want a ready-to-use RSI value rather than computing it yourself from OHLCV data.
Side effects
- Invalid or unknown asset slug returns an error or empty result
- Network timeout if CoinCap servers are temporarily unavailable
- Insufficient historical price data for a newly listed asset may prevent RSI computation
- Payment failure (x402) if USDC balance is insufficient or payment is not properly submitted
- Rate limiting if too many requests are made in a short window
