CloudMaxi0x EMA Indicator is a paid API for AI agents from cloudmaxi0x.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns a converged, SMA-seeded exponential moving average time series for a given symbol, interval, and date range, with warm-up history pre-fetched and discarded so all returned values are stable.

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 EMA values aligned to closed candle timestamps within the requested half-open range. Each value is SMA-seeded and warm-up-converged, published at the precision level that exactly reproduces the computation. The first returned value is already stable — it does not change when the same dates are recomputed from a longer range.
Example use cases
EMA crossover strategy signal generation
“Pull me the 12-period and 26-period EMA for ETHUSDT on 4-hour candles from March 1 2024 00:00 UTC to April 1 2024 00:00 UTC — I need fully converged values so I can detect crossover signals without warm-up drift.”
Backtesting momentum strategy with EMA
“I'm backtesting a momentum strategy and need a stable 50-period EMA for SOLUSDT on the 1-day interval from January 1 2023 00:00 UTC to January 1 2024 00:00 UTC — make sure the first value is already converged so my backtest results don't vary depending on the lookback window.”
Live trading dashboard EMA overlay
“Get me the 9-period EMA for BTCUSDT on 15-minute candles for the last 24 hours — I want values I can overlay on my chart without them jumping around as new data comes in.”
Technical details
Endpoint
GEThttps://cloudmaxi0x.com/v1/indicators/emaWhen to prefer
Choose this endpoint when you need EMA values that are guaranteed to be stable and convergent — i.e., when the same date range must return identical values regardless of how far back you extend the query. It is specifically useful for backtesting pipelines, charting overlays, and multi-indicator strategies where EMA warm-up artifacts would corrupt results. Prefer it over computing EMA yourself from raw OHLCV data when you need SMA-seeded initialization and reproducible precision.
Side effects
- start_ms or end_ms not an exact multiple of the interval — request rejected with validation error
- Symbol not supported or misspelled — returns error or empty series
- end_ms not strictly greater than start_ms — invalid range error
- Insufficient historical data before start_ms to complete warm-up — may return error or partial series
- Payment failure via x402 protocol — 402 response before any data is returned
- Interval enum value not recognized — schema validation error
