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
Returns a time series of Bollinger Band values for each candle in the requested range, including the middle band (SMA), upper band (SMA + 2 std dev), and lower band (SMA - 2 std dev). Values are already converged because warm-up bars are fetched before the range and discarded, ensuring consistency regardless of the window requested. Precision matches the level that actually reproduces the computation.
Example use cases
Crypto volatility squeeze detection
“Pull the Bollinger Bands for ETHUSDT on the 4-hour interval from March 1 2025 00:00 UTC to March 31 2025 00:00 UTC so I can find where the bands squeezed and then expanded.”
Algorithmic trading signal generation
“I need Bollinger Band data for SOLUSDT on the 15-minute interval from April 10 2025 00:00 UTC to April 11 2025 00:00 UTC — I want to flag candles where the close touched or crossed the upper or lower band.”
Backtesting mean-reversion strategy
“Fetch the 20-period Bollinger Bands for BTCUSDT on the daily interval from January 1 2024 00:00 UTC to December 31 2024 00:00 UTC so I can backtest a mean-reversion strategy that buys at the lower band and sells at the middle.”
Technical details
Endpoint
GEThttps://cloudmaxi0x.com/v1/indicators/bollingerWhen to prefer
Choose this endpoint when you need Bollinger Band values that are guaranteed to be converged from the first returned bar, critical for backtesting and algorithmic trading where inconsistent warm-up handling causes look-ahead bias or result discrepancies. Prefer this over self-computed BB when you need reproducible precision and don't want to manage warm-up history fetching yourself. Especially useful when comparing BB values across different date ranges and requiring consistency.
Side effects
- start_ms or end_ms not an exact multiple of the interval — returns 400 error
- Symbol not found or unsupported exchange — returns 404 or empty data
- End timestamp not exclusive multiple of interval — misaligned range error
- Network timeout for long historical ranges
- Payment failure via x402 protocol — 402 response if USDC payment not attached
- Period value too large relative to available history before start_ms
