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 list of closed OHLCV candles for the requested symbol and interval within the specified half-open time range, with exchange-native decimal strings preserved byte-for-byte, plus a SHA-256 Merkle manifest root that uniquely and deterministically identifies this exact dataset. The same query parameters always return the same root, enabling cryptographic verification.
Example use cases
Reproducible backtest data pull
“Get me all the 15-minute BTCUSDT candles from Binance for the entire month of March 2024 — I need the Merkle manifest root so my backtesting run is fully auditable and reproducible.”
Quantitative strategy research
“Pull the 4-hour ETHUSDT candles from Binance between November 1 2023 and December 1 2023 so I can run a quant analysis — make sure exchange decimal precision is preserved exactly as returned.”
Pre-trade data integrity check
“Fetch the daily SOLUSDT candles from January 1 2024 to April 1 2024 with the SHA-256 Merkle root so our compliance team can verify we used untampered price data in our model.”
Technical details
Endpoint
GEThttps://cloudmaxi0x.com/v1/data/ohlcvWhen to prefer
Choose this endpoint when you need cryptographically verifiable, reproducible OHLCV data — i.e. when auditability, determinism, and tamper-evidence matter, such as for backtesting audits, compliance workflows, or research that must be independently reproduced. Prefer it over generic market data APIs when you need a Merkle proof to confirm data integrity, or when you need exchange-native decimal precision preserved exactly. Not suitable for real-time streaming or live tick data needs.
Side effects
- start_ms or end_ms not aligned to an exact multiple of the interval — returns 400 error
- end_ms not greater than start_ms — invalid range error
- unsupported symbol or interval enum value — validation error
- requested range too large — potential timeout or payload size limit
- Binance source unavailable or data gap in range — partial or error response
- Missing required query parameters (symbol, interval, start_ms, end_ms) — 400 bad request
- Payment not provided or insufficient — 402 Payment Required
