# CloudMaxi0x ADX Indicator

> CloudMaxi0x ADX Indicator is a paid API for AI agents from cloudmaxi0x.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-16).

Returns converged Average Directional Index (ADX) with +DI and -DI values for a given symbol, interval, and time range, with warm-up pre-fetched so the first returned value is already fully converged.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-adx-indicator-25e4dab1
```

Example prompt: Pull the ADX (period 14) with +DI and -DI for BTCUSDT on the 4-hour chart from January 1 2025 00:00 UTC to February 1 2025 00:00 UTC — I need fully converged values with no warm-up bias.

## When to prefer this

Use this endpoint when you need numerically reproducible, warm-up-converged ADX values — especially for backtesting or strategy validation where cold-start bias would cause your computed values to diverge from a longer reference run. Prefer this over computing ADX yourself if you need guaranteed precision and convergence without managing warm-up data fetching manually.

## Known failure modes

- Invalid symbol returns an error — symbol must be a valid exchange pair like BTCUSDT
- start_ms or end_ms not an exact multiple of the interval causes a validation error
- end_ms not strictly greater than start_ms results in an invalid range error
- Requesting a future range with no available candle data returns empty or error
- Network or payment failure returns 402 or connection error

## 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 of ADX, +DI, and -DI values at the precision that accurately reproduces the computation, covering the exact requested range with the first value already converged (warm-up bars are pre-fetched and discarded server-side).
