Daily OHLCV stock price data from Alpha Vantage, pay-per-call via MPP/Tempo.
What it does
This endpoint provides daily time-series stock price data (open, high, low, close, volume) sourced from Alpha Vantage, accessed through the Locus MPP (Micropayment Protocol) gateway. It accepts a POST request with a stock ticker symbol and returns historical daily price data. You can choose between "compact" output (latest 100 data points) or "full" output (20+ years of history), and select JSON or CSV format.
The endpoint is part of a broader Alpha Vantage MPP service that exposes 26 financial data endpoints covering intraday/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 analysis indicators (SMA, EMA, MACD, RSI, Bollinger Bands). All endpoints share the same per-call pricing.
Payment is handled via the Tempo method on the MPP protocol with a charge intent. Each call costs 8,000 base units of pathUSD (currency address 0x20c0...b9537d11c60e8b50). Assuming pathUSD uses 6 decimals, this equates to $0.008 (less than one cent) per request. The endpoint is a POST-only route; HEAD and GET probes return 404, which is expected behavior for this API design.

Quick start
curl -X POST https://alphavantage.mpp.paywithlocus.com/alphavantage/time-series-daily \
-H "Content-Type: application/json" \

"outputsize": "compact"
}Endpoint
Quality
Full OpenAPI schema with detailed request parameters and payment info is available. However, the probe returned 404 because HEAD/GET were used on a POST-only endpoint, so liveness via 402 challenge was not directly confirmed. No response schema or example response is documented. Crawled pages all returned generic 404 JSON, providing no additional documentation.
Warnings
- —Endpoint returned 404 on HEAD and GET probes; it is POST-only, so liveness could not be confirmed via the standard MPP 402 challenge
- —No response schema is documented in the OpenAPI spec — only '200: Successful response' with no body definition
- —Currency address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD with 6 decimals; if decimals differ, the stated price of $0.008 would be incorrect
- —No example responses available from probe or crawl data
