How this service works
Deterministic, verifiable crypto market data and honest backtest audits. Use GET /v1/data/ohlcv for exact OHLCV over a half-open range with a SHA-256 Merkle manifest - only closed candles are returned, exchange decimal strings are preserved byte for byte, so the same query always yields the same root. Use GET /v1/data/proof to verify one candle against a root you already hold. Use POST /v1/validate/trades to find out whether a list of trade returns can be distinguished from luck, and POST /v1/validate/filter to test a trade filter against a permutation null. GET /, /v1/schema and /v1/data/sources are free.
Output
A time series of RSI values (Wilder-smoothed, converged) for the requested symbol and interval over the specified epoch-ms date range, at the precision that accurately reproduces the indicator. Warm-up candles are fetched internally and discarded, so the first returned value is already converged and consistent with what a longer range computation would produce.
Example use cases
Backtest RSI overbought/oversold strategy
“Pull the 14-period RSI for ETHUSDT on the 4h interval from July 1, 2023 00:00 UTC to December 31, 2023 00:00 UTC — I need fully converged values so my backtest results don't drift when I extend the date range.”
Live trading signal dashboard
“Fetch the current RSI for SOLUSDT on the 15m interval for the last 7 days — I want to see if it's crossed above 30 or below 70 recently to trigger a buy or sell signal.”
Multi-symbol RSI screener
“Get me the RSI with period 9 for BNBUSDT on the daily interval from March 1, 2024 to April 1, 2024 — I'm screening for assets with RSI under 35 to find oversold opportunities.”

Endpoint
GEThttps://cloudmaxi0x.com/v1/indicators/rsiWhen to prefer
Choose this endpoint when you need fully converged RSI values for a specific date range without implementing your own warm-up logic. It is particularly valuable for backtesting, where naïve RSI computed only over the requested window produces different (incorrect) values than RSI computed from a longer history — this endpoint handles that automatically. Prefer it over rolling your own RSI when you need reproducible, consistent indicator values across different range queries on the same dates.
Side effects
- Invalid symbol returns an error (e.g. unrecognized trading pair)
- start_ms or end_ms not aligned to exact multiples of the requested interval causes a validation error
- end_ms is exclusive but treated as inclusive leads to off-by-one errors in range selection
- Requesting a very short range relative to the period may return fewer bars than expected
- Payment failure via x402 protocol results in 402 response and no data returned
- Rate limits may apply for rapid sequential calls
