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 array of SMA values aligned to closed candles within the requested half-open range [start_ms, end_ms), at the requested interval. Each data point includes the timestamp and the SMA value at full precision. The first returned value is already converged because warm-up bars are fetched prior to start_ms and silently discarded, ensuring consistency regardless of range width.
Example use cases
Crypto trend detection for a trading bot
“Get me the 50-period daily SMA for ETHUSDT from December 1 2024 to March 1 2025 — I need every value to be fully converged so my bot can check whether price is above or below the moving average at each candle.”
Backtesting SMA crossover strategy
“I'm backtesting a 20-and-50 SMA crossover on SOLUSDT with 4-hour bars. Fetch the 20-period SMA from July 1 2024 00:00 to September 1 2024 00:00 — the first value must already be converged, not in warm-up.”
Dashboard display of current SMA trend
“Pull the 20-period 1-hour SMA for BTCUSDT for today — from midnight UTC to now — so I can display the current moving average trend line on my trading dashboard.”
Technical details
Endpoint
GEThttps://cloudmaxi0x.com/v1/indicators/smaWhen to prefer
Use this endpoint when you need a Simple Moving Average that is guaranteed to be converged at the first returned bar — critical for backtesting, strategy evaluation, or any comparison across different date ranges where consistency matters. Prefer this over computing SMA locally when you want server-side warm-up management and reproducible precision. Choose SMA over EMA when you need equal-weight averaging without exponential decay.
Side effects
- start_ms or end_ms not an exact multiple of the interval — request rejected
- symbol not supported or misspelled — no data returned
- start_ms >= end_ms — invalid range error
- interval enum value not in allowed list — validation error
- Payment not attached or insufficient — 402 Payment Required
- No candles available in the requested range — empty result or error
