It is part of a broader Alpha Vantage suite exposed through the Locus MPP (Micropayment Protocol) gateway, which wraps the upstream Alpha Vantage API and settles payments via Tempo L2 using pathUSD. Each call costs 8,000 base units of pathUSD (6 decimals), which equals $0.008 per request.\n\nThe endpoint accepts POST requests with a JSON body containing two required fields: `symbol` (the cryptocurrency ticker, e.g., \"BTC\", \"ETH\") and `market` (the fiat or quote currency, e.g., \"USD\"). The response format follows Alpha Vantage's standard Digital Currency Daily output, providing daily time-series data with OHLCV values. Output can be returned as JSON (default) or CSV.\n\nThis specific endpoint is one of 26 Alpha Vantage endpoints available through the Locus MPP gateway, covering equities, forex, crypto, commodities, economic indicators, technical analysis (SMA, EMA, MACD, RSI, Bollinger Bands), fundamentals (income statement, balance sheet, cash flow, earnings), and news sentiment. All endpoints share the same per-call price of $0.008. The probe returned 404 on HEAD/GET, which is expected since the endpoint requires POST; the OpenAPI spec confirms the POST method with a 402 payment challenge.","tags":["finance","stocks","forex","crypto","market-data","technical-analysis"],"capabilities":["crypto-daily-ohlcv","digital-currency-historical","pay-per-call","tempo-l2-settlement","json-csv-output","alpha-vantage-proxy"],"categories":["data","finance","crypto"],"synonyms":["cryptocurrency daily prices","digital currency daily","crypto OHLCV","BTC daily history","ETH daily price","Alpha Vantage crypto","crypto time series","digital asset daily data"],"warnings":["Probe returned 404 on HEAD and GET; endpoint is POST-only so liveness could not be confirmed via the probe's methods","No response schema or example response is provided in the OpenAPI spec","Currency address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD with 6 decimals based on the Tempo settlement method; if decimals differ, the $0.008 price would be incorrect","Upstream Alpha Vantage data coverage and freshness depend on Alpha Vantage's own data pipeline"],"endpointUrl":"https://alphavantage.mpp.paywithlocus.com/alphavantage/digital-currency-daily","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"alphavantage.mpp.paywithlocus.com","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.620","qualityRationale":"Full OpenAPI schema with clear request parameters and payment info is available.
