# CloudMaxi0x OHLCV Data Feed

> CloudMaxi0x OHLCV Data Feed is a paid API for AI agents from cloudmaxi0x.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Returns deterministic, SHA-256 Merkle-anchored OHLCV candlestick data for a specified crypto trading pair, interval, and half-open time range — only closed candles, with exchange decimal strings preserved verbatim.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cloudmaxi0x-ohlcv-data-feed-f4f3fe9c
```

Example prompt: Fetch me the 1-hour OHLCV candles for BTCUSDT from Binance between January 1 2024 00:00 UTC and January 8 2024 00:00 UTC — I need the Merkle root so I can verify the data later.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
