How this service works
US stock market data, sold per request over x402. Every path here answers 402 with the payment terms in the PAYMENT-REQUIRED header, and answers with the data once the payment settles. No account, no API key, no subscription.
Output
Returns a JSON object containing an array of SMA values each with a computed value and Unix millisecond timestamp, along with underlying aggregate OHLC bars used in the calculation, a next_url cursor for pagination, a request ID, and a status field. Payment is settled automatically via x402 before data is returned.
Example use cases
Daily SMA for portfolio monitoring
“Pull the 50-day SMA for NVDA using daily close prices, give me the last 20 values in descending order — I want to see if it's trending above or below its average.”
Technical analysis with custom window
“Get me a 200-day moving average for SPY based on daily close prices, most recent 10 results, split-adjusted, so I can check the long-term trend.”
Intraday SMA on hourly bars
“Fetch the 10-period SMA for TSLA on an hourly timespan using close prices, limit to 5 results in ascending order, from 2024-01-15 onward.”

Endpoint
GEThttps://agent.massive.com/v1/indicators/sma/%7BstockTicker%7DWhen to prefer
Choose this endpoint when you need on-demand, pay-per-call SMA data for US stocks without signing up for a subscription or managing API keys. It is ideal for AI agents that make infrequent or variable-volume requests to technical indicator data and can settle micropayments via x402. Prefer this over subscription-based financial data APIs when cost should scale strictly with usage, or when operating in a wallet-enabled agent environment.
Side effects
- 402 Payment Required if x402 payment header is missing or payment fails — response includes payment terms in PAYMENT-REQUIRED header
- Invalid or unknown ticker symbol returns an error or empty results
- Out-of-range limit (above 5000) rejected by schema validation
- Invalid timespan or series_type enum value returns a bad request error
- Malformed timestamp format (not YYYY-MM-DD or millisecond epoch) causes query failure
- No data available for the requested date range returns empty values array
