Get real-time and historical stock quotes via Alpha Vantage, paid per-call over MPP/Tempo.
What it does
The Alpha Vantage Global Quote endpoint, served through the Locus MPP (Micropayment Protocol) gateway, returns the latest price, volume, and change data for a given stock ticker symbol. It is one of 26 Alpha Vantage endpoints available on this gateway, covering equities, forex, crypto, commodities, economic indicators, technical analysis (SMA, EMA, MACD, RSI, Bollinger Bands), news sentiment, earnings transcripts, and fundamental data (income statements, balance sheets, cash flow).
Each call costs 8,000 base units of pathUSD on Tempo L2 (currency address 0x20c…8b50). Assuming pathUSD uses 6 decimals, that works out to $0.008 (less than one cent) per request. Payment is handled inline via the MPP charge intent — no API key or subscription required; the agent simply settles the micropayment with each POST request.
The Global Quote endpoint accepts a JSON body with a required `symbol` field (e.g., "IBM", "AAPL") and an optional `datatype` field ("json" or "csv"). The upstream data comes from Alpha Vantage (alphavantage.co). Note that the probe returned 404 on HEAD/GET because this endpoint only accepts POST requests, which is consistent with the OpenAPI spec; the endpoint is expected to be live when called with the correct method and a valid payment.

Quality
Full OpenAPI schema with 26 endpoints and clear request schemas are available. However, the probe did not capture a live 402 challenge (HEAD/GET returned 404 because the endpoint is POST-only), no example response body is documented, and the crawl pages all returned generic 404 JSON. The currency decimals for pathUSD are inferred (6 decimals) but not confirmed in the probe data.
Warnings
- —Probe returned 404 on HEAD and GET; endpoint is POST-only per the OpenAPI spec — likely live but not confirmed with a 402 challenge on POST
- —pathUSD decimal count assumed to be 6; price of $0.008 per call is inferred, not verified
- —No example response schema or sample response is provided in the OpenAPI spec
- —Upstream Alpha Vantage data coverage and freshness depend on Alpha Vantage's own availability
