Implementations

impl Indexes

pub async fn get_index_list(&self) -> Result<Vec<IndexSymbol>>

Get list of available market indexes

Returns all available market index symbols (S&P 500, Nasdaq, Dow Jones, etc.).

Example

let client = FmpClient::new()?;
let indexes = client.indexes().get_index_list().await?;
for index in indexes.iter().take(10) {
    println!("{}: {}", index.symbol, index.name.as_deref().unwrap_or("N/A"));
}

pub async fn get_index_quote(&self, symbol: &str) -> Result<Vec<IndexQuote>>

Get real-time index quote

Returns current level and market data for an index.

Arguments

• symbol - Index symbol (e.g., “^GSPC” for S&P 500, “^DJI” for Dow Jones)

Example

let client = FmpClient::new()?;
let quote = client.indexes().get_index_quote("^GSPC").await?;
if let Some(q) = quote.first() {
    println!("S&P 500: {:.2}", q.price.unwrap_or(0.0));
    println!("Change: {:+.2}%", q.changes_percentage.unwrap_or(0.0));
}

pub async fn get_index_historical( &self, symbol: &str, from: Option<&str>, to: Option<&str>, ) -> Result<Vec<IndexHistorical>>

Get historical index data

Returns daily historical data for an index.

Arguments

• symbol - Index symbol (e.g., “^GSPC”)
• from - Start date (optional, format: YYYY-MM-DD)
• to - End date (optional, format: YYYY-MM-DD)

Example

let client = FmpClient::new()?;
let history = client.indexes().get_index_historical("^GSPC", None, None).await?;
for day in history.iter().take(5) {
    println!("{}: {:.2}", day.date, day.close);
}

pub async fn get_index_constituents( &self, symbol: &str, ) -> Result<Vec<IndexConstituent>>

Get index constituents

Returns all component stocks that make up an index (e.g., S&P 500 companies).

Arguments

• symbol - Index symbol (e.g., “^GSPC” for S&P 500 constituents)

Example

let client = FmpClient::new()?;
let constituents = client.indexes().get_index_constituents("^GSPC").await?;
println!("S&P 500 has {} components", constituents.len());
for stock in constituents.iter().take(10) {
    println!("{}: {} ({})",
        stock.symbol,
        stock.name.as_deref().unwrap_or("N/A"),
        stock.sector.as_deref().unwrap_or("N/A"));
}
