Bollinger Bands technical indicator via Alpha Vantage, pay-per-call over MPP/Tempo.
What it does
This endpoint computes Bollinger Bands (BBANDS) for a given stock ticker symbol through the Alpha Vantage API, proxied via the Locus MPP (Micropayment Protocol) gateway. Bollinger Bands consist of a middle SMA band and upper/lower bands offset by a configurable number of standard deviations, commonly used to identify overbought/oversold conditions and volatility.
The endpoint accepts POST requests with required parameters: symbol, interval (1min through monthly), time_period (number of data points, e.g. 20), and series_type (close, open, high, low). Optional parameters include nbdevup/nbdevdn (standard deviation multipliers, default 2), matype (moving average type from SMA to MAMA, 9 options), month (for historical intraday slicing), and datatype (json or csv). Payment is settled per-call via the Tempo method at $0.008 per request (8000 base units of pathUSD with 6 decimals).
This is one of 26+ endpoints in the Alpha Vantage MPP service, which also covers time series (intraday, daily, weekly, monthly), fundamentals (income statement, balance sheet, cash flow, earnings), forex, crypto, commodities, economic indicators, news sentiment, and other technical indicators (SMA, EMA, MACD, RSI). All endpoints share the same per-call price. The upstream data source is Alpha Vantage (alphavantage.co). Note that the probe returned 404 on HEAD/GET — this endpoint requires POST requests as specified in the OpenAPI schema.
Capabilities
Use cases
- —Computing Bollinger Bands for a stock to detect overbought/oversold signals in a trading bot
- —Overlaying volatility bands on price charts in a financial dashboard
- —Screening multiple tickers for Bollinger Band squeezes indicating upcoming breakouts
- —Backtesting trading strategies that rely on Bollinger Band crossovers
- —Feeding Bollinger Band data into an AI agent for automated portfolio analysis
Fit
Best for
- —Agents and bots needing on-demand technical analysis without API key management
- —Pay-per-call access to Bollinger Bands without a subscription commitment
- —Programmatic access to configurable BBANDS across multiple timeframes and MA types
Not for
- —High-frequency trading requiring sub-second latency (per-call payment adds overhead)
- —Bulk historical data downloads where a direct Alpha Vantage subscription would be cheaper
- —Real-time streaming price data (this is a request-response endpoint)
Quick start
curl -X POST https://alphavantage.mpp.paywithlocus.com/alphavantage/bbands \
-H "Content-Type: application/json" \
-d '{"symbol": "AAPL", "interval": "daily", "time_period": 20, "series_type": "close"}'Example
Request
{
"matype": 0,
"symbol": "AAPL",
"nbdevdn": 2,
"nbdevup": 2,
"interval": "daily",
"series_type": "close",
"time_period": 20
}Endpoint
Quality
Full OpenAPI schema with detailed request parameters and payment info is available. However, the probe returned 404 on HEAD/GET (expected since the endpoint requires POST), no actual 402 challenge was captured for this specific path, no response schema or example response is documented, and all crawled pages returned generic 404 JSON. Price is clear from x-payment-info.
Warnings
- —Probe did not capture a 402 MPP challenge — endpoint requires POST but probe only tried HEAD and GET
- —No response schema documented; response format must be inferred from Alpha Vantage upstream docs
- —Currency address 0x20c000000000000000000000b9537d11c60e8b50 assumed to be pathUSD (6 decimals) based on Tempo method context; not independently verified
- —No example response available in the OpenAPI spec or crawled content
