Intraday stock price data from Alpha Vantage, pay-per-call via MPP/Tempo.
What it does
This endpoint provides intraday time-series data for equities through Alpha Vantage, proxied via the Locus MPP (Micropayment Protocol) gateway. You send a POST request with a stock ticker symbol and a time interval (1min, 5min, 15min, 30min, or 60min), and receive OHLCV (open, high, low, close, volume) price data. Additional options include adjusted prices, extended-hours (pre/post-market) data, historical month selection (YYYY-MM format), output size (compact for latest 100 data points or full for 20+ years), and JSON or CSV output format.
This is one endpoint in a broader Alpha Vantage suite available through the same Locus MPP gateway. Sibling endpoints cover daily/weekly/monthly time series, global quotes, symbol search, market status, top gainers/losers, news sentiment, earnings call transcripts, company fundamentals (overview, income statement, balance sheet, cash flow, earnings), forex and crypto exchange rates, commodity prices, economic indicators, and technical indicators (SMA, EMA, MACD, RSI, Bollinger Bands). All endpoints share the same pricing.
Payment is per-call via the Tempo method (settling in pathUSD on Tempo L2). The advertised amount is 8,000 base units of pathUSD (6 decimals), which equals $0.008 per request. The endpoint is a POST-only route; HEAD and GET probes returned 404, which is expected since the OpenAPI spec defines only POST. The full OpenAPI schema is available and well-documented with parameter descriptions and required fields.
Capabilities
Use cases
- —Fetching 1-minute or 5-minute candle data for algorithmic trading strategies
- —Building real-time stock dashboards with intraday price updates
- —Backtesting trading models using historical intraday data for specific months
- —AI agents autonomously purchasing market data on a per-call basis without API key management
- —Comparing pre-market and post-market price action using extended-hours data
Fit
Best for
- —AI agents needing pay-per-call stock data without subscription commitments
- —Developers building financial tools who want micropayment-based access to Alpha Vantage
- —Backtesting workflows requiring granular intraday historical data
Not for
- —High-frequency trading requiring sub-second latency (HTTP overhead + payment negotiation adds latency)
- —Bulk data downloads where a direct Alpha Vantage subscription would be more cost-effective
- —Real-time streaming price feeds (this is request/response, not WebSocket)

}Endpoint
Quality
Full OpenAPI schema with detailed parameter descriptions and clear pricing. However, the probe returned 404 on HEAD/GET (expected for POST-only), no actual 402 challenge was captured for this specific endpoint, no response schema or example response is documented, and crawled pages yielded no additional documentation.
Warnings
- —No 402 MPP challenge was captured during probing — the endpoint only accepts POST, and the probe used HEAD/GET. Liveness not directly confirmed for this specific path.
- —Response schema is not documented in the OpenAPI spec; only '200: Successful response' is stated without a body schema.
- —Currency address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD with 6 decimals based on the Tempo method context; this is not explicitly confirmed in the probe data.
- —No example responses available from crawl or probe data.
