Jentic publishes the only available OpenAPI specification for Alpha Vantage API, keeping it validated and agent-ready. Alpha Vantage exposes free and premium market-data endpoints for stocks, options, forex, crypto, commodities, economic indicators, and over 50 technical indicators, all served from a single /query path that selects the dataset via a 'function' parameter. Authentication is by apikey query string, and the catalogue spans realtime quotes, historical OHLC, fundamentals, news sentiment, and macro series. The API is widely used for trading research, dashboarding, and lightweight backtesting.

Use Cases

Patterns agents use Alpha Vantage API API for, with concrete tasks.

★ Trading Research and Backtesting

Quants and retail traders pull historical OHLC, technical indicators, and fundamentals from Alpha Vantage to feed research notebooks and lightweight backtests. Because every dataset routes through the single /query endpoint, the integration is one HTTP client plus a function-parameter dispatcher. The free tier covers most prototyping; production research uses a premium key for higher throughput.

Call GET /query with function=TIME_SERIES_DAILY_ADJUSTED, symbol=AAPL, outputsize=full, and apikey to retrieve adjusted daily bars, then compute returns in the agent.

Forex and Crypto Rate Conversion

Finance and accounting teams use Alpha Vantage to fetch exchange rates for currency conversion in invoicing, expense management, and reporting. The CURRENCY_EXCHANGE_RATE and DIGITAL_CURRENCY_DAILY functions cover both fiat pairs and major crypto pairs, and the realtime quote endpoint is sufficient for end-of-day reporting use cases.

Call GET /query with function=CURRENCY_EXCHANGE_RATE, from_currency=USD, to_currency=EUR, and apikey, then store the rate against today's reporting date.

Economic Indicator Dashboards

Macro analysts pull Alpha Vantage's economic indicator endpoints (CPI, real GDP, treasury yield curve, federal funds rate) into BI dashboards to track US economic conditions. The series come back already cleaned and time-stamped, so dashboards refresh on a single scheduled call per indicator.

Call GET /query with function=CPI, interval=monthly, and apikey, then upsert the latest reading into the macro dashboard's CPI table.

AI Agent Market Research via Jentic

An AI research agent built on Jentic resolves natural-language requests like 'how has TSLA moved this week and what's the news sentiment?' to two Alpha Vantage calls (TIME_SERIES_INTRADAY and NEWS_SENTIMENT) without the agent ever needing to memorise the function-parameter catalogue. Jentic isolates the apikey in MAXsystem.

Search Jentic for 'get a stock price and news sentiment', load the /query schema with function=TIME_SERIES_INTRADAY and function=NEWS_SENTIMENT, and execute both for the requested ticker.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Alpha Vantage apikeys are stored encrypted in the Jentic vault (MAXsystem) and injected into the query string at call time. Agents never see the raw apikey, which prevents leakage through transcripts or shared URLs.

Intent-based discovery

Agents search Jentic by intent (e.g., 'get a stock price' or 'compute RSI for a ticker') and Jentic returns the /query operation prefilled with the appropriate function parameter, so the agent doesn't need to memorise Alpha Vantage's function catalogue.

Time to first call

Direct Alpha Vantage integration: a few hours to map the function catalogue, handle rate-limit notes in JSON bodies, and parse each dataset's distinct response shape. Through Jentic: under an hour to search, load, and execute the first market-data call.

Choose Marketstack for a leaner equities-only feed when forex, crypto, and technical indicators are not needed.

FAQs

Specific to using Alpha Vantage API API through Jentic.

Why is there no official OpenAPI spec for Alpha Vantage API?

Alpha Vantage does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Alpha Vantage API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Alpha Vantage API use?

Alpha Vantage uses an apikey passed as a query string parameter on every /query request. Through Jentic, the key is stored encrypted in the MAXsystem vault and injected into the URL at execution time, so the apikey never appears in agent prompts.

Can I get realtime stock quotes with the Alpha Vantage API?

Yes. Call GET /query with function=GLOBAL_QUOTE and the symbol parameter for a near-realtime snapshot, or function=TIME_SERIES_INTRADAY with interval=1min for live intraday bars on premium tiers.

What are the rate limits for the Alpha Vantage API?

The free tier is documented at 25 requests per day with a per-minute cap; premium tiers raise both daily and per-minute throughput. Plan ingestion against your tier and back off on 429 responses or 'Note' fields in the JSON body that signal soft limits.

How do I pull a stock price through Jentic?

Run pip install jentic, then search with 'get a stock price'. Load the /query schema, set function=GLOBAL_QUOTE and symbol=AAPL, and execute. Jentic handles the apikey injection and URL assembly.

Is the Alpha Vantage API free?

There is a free tier with a low daily quota (25 calls/day). Higher-throughput, lower-latency, and additional premium endpoints (news sentiment, top movers, real-time options) require a paid plan from alphavantage.co.
