Alpha Vantage

Cargo Docs

docs.rs/finance-query — Provider::AlphaVantage

Feature flag required

finance-query = { version = "...", features = ["alphavantage"] }

Alpha Vantage provides financial data with best-in-class technical indicator coverage (50+ indicators), plus economic indicators, forex, crypto, and commodities. Free tier: 25 requests per day.

Setup

Set the API key via environment variable:

export ALPHAVANTAGE_API_KEY="your-alphavantage-key"

No manual init call needed — the provider reads the key during TickerBuilder::build().

Usage

use finance_query::{Capability, Fetch, Provider, Providers, Raw};

let providers = Providers::builder()
    .route(Capability::QUOTE, &[Provider::AlphaVantage, Provider::Yahoo])
    .fetch(Fetch::Sequential)
    .build()
    .await?;
let ticker = providers.ticker("AAPL").build().await?;
let quote = ticker.quote::<Raw>().await?;
