How this service works

Financial market data — stock prices, forex, crypto, commodities, economic indicators, technical analysis, and news sentiment.

Output

Returns a JSON object containing a time-series of EMA values keyed by timestamp, along with payment settlement details (settled USDC amount, authorized max USDC) and a request tracking ID. The EMA data is nested under the 'data' field and reflects the computed exponential moving average for the specified symbol, interval, series type, and time period.

Example use cases

EMA crossover signal for trading bot

“Get me the 12-period and 26-period daily EMA for MSFT on closing prices so I can check for a bullish crossover signal.”

Intraday momentum analysis

“Fetch the 9-period EMA for SPY using 5-minute intervals for November 2024 — I want to analyze intraday momentum.”

Trend confirmation for portfolio rebalancing

“What's the 50-period weekly EMA for NVDA based on closing prices? I need to confirm whether it's in an uptrend before rebalancing.”

When to prefer

Choose this endpoint when you need EMA technical indicator data specifically — not raw price data — and want pay-per-call micropayment billing via x402 with no subscription required. It is ideal for algorithmic trading agents, momentum strategy bots, or any workflow that needs programmatic EMA values for any interval from 1-minute intraday to monthly, without managing an Alpha Vantage API key directly.

Side effects

Invalid or unsupported ticker symbol returns empty or error data
Unsupported interval value causes a bad request response
Missing required fields (symbol, interval, time_period) may result in an error
Intraday month filtering only valid for intraday intervals (1min–60min); using with daily/weekly/monthly may fail
Payment failure or insufficient USDC balance blocks the call
Rate limiting from upstream Alpha Vantage may cause delayed or failed responses
