Check the open/closed status of global financial markets via Alpha Vantage, paid per call over MPP.
What it does
This endpoint returns the current trading status of global financial markets (open, closed, pre-market, etc.) via Alpha Vantage's Market Status API, proxied through the Locus MPP (Micropayment Protocol) gateway. It is one of 26 endpoints in the Alpha Vantage MPP service covering stock time series, forex, crypto, commodities, economic indicators, technical analysis, news sentiment, and fundamental data.
The market-status endpoint requires no request body — it is a simple POST call. Each call costs 8,000 base units of pathUSD on Tempo L2 (currency address 0x20c000000000000000000000b9537d11c60e8b50). Assuming pathUSD uses 6 decimals, that equates to $0.008 per request. Payment is settled per-call (intent: "charge", method: "tempo"). The endpoint is defined as a POST in the OpenAPI spec; the probe attempted HEAD and GET and received 404, which is expected given the POST-only routing.
The broader Alpha Vantage MPP service exposes endpoints for intraday/daily/weekly/monthly time series, global quotes, symbol search, top gainers & losers, news sentiment, earnings call transcripts, company overview, income statements, balance sheets, cash flow, earnings, currency and crypto exchange rates, FX daily, digital currency daily, commodity prices, economic indicators, and technical indicators (SMA, EMA, MACD, RSI, Bollinger Bands). All share the same per-call price. Full upstream API documentation is available at alphavantage.co/documentation/.

Quality
The OpenAPI spec is well-structured with 26 endpoints and clear schemas, and pricing is explicit. However, the specific market-status endpoint returned 404 on HEAD/GET (expected since it's POST-only), no actual 402 challenge was captured for this endpoint, no response schema or example response is documented, and crawled pages returned only generic 404 JSON. The upstream Alpha Vantage docs exist but were not crawled.
Warnings
- —Probe did not capture a 402 MPP challenge — HEAD and GET returned 404; the endpoint is POST-only per the OpenAPI spec, so liveness could not be confirmed via the probe methods used.
- —No response schema is provided in the OpenAPI spec; response structure is undocumented.
- —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.
