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 Merkle inclusion proof demonstrating whether the specified candle (identified by open_time) is authentically part of the dataset for the given symbol, interval, and time range. The proof allows independent verification against the SHA-256 Merkle root without re-fetching the full OHLCV dataset.
Example use cases
Backtest data integrity audit
“I ran a backtest on ETH/USDT 15-minute candles from 1698768000000 to 1698854400000 and got a Merkle root — can you prove that the candle at open_time 1698771600000 is legitimately part of that dataset?”
Regulatory compliance candle attestation
“For our compliance report, I need a cryptographic proof that the BTC/USDT 1-day candle with open_time 1697760000000 within the range 1697760000000 to 1697846400000 matches the root we recorded last month.”
Third-party data verification
“A counterparty sent me OHLCV data for SOL/USDT at the 4-hour interval — can you verify that the candle at open_time 1699920000000 in the range 1699920000000 to 1699948800000 is legitimate and matches the Merkle root they also provided?”
Technical details
Endpoint
GEThttps://cloudmaxi0x.com/v1/data/proofWhen to prefer
Use this endpoint when you already hold a Merkle root from a prior OHLCV query and need to cryptographically verify a single candle without re-downloading the full dataset. Ideal for audit trails, compliance attestations, and third-party data validation where tamper-evidence is required. Prefer this over re-fetching full OHLCV data when you only need to prove one specific candle's authenticity efficiently and cheaply.
Side effects
- Candle open_time falls outside the specified start_ms/end_ms range — returns error indicating candle not in range
- Symbol or interval not supported — returns 404 or validation error
- Malformed timestamp integers — returns 400 bad request
- open_time points to an unclosed candle — not included in proof
- Network or payment failure — 402 if payment not provided, 503 on service unavailability
