This project provides a set of functions to receive data from the the yahoo! finance website via their API. This project is licensed under Apache 2.0 or MIT license (see files LICENSE-Apache2.0 and LICENSE-MIT).
Since version 0.3 and the upgrade to reqwest
0.10, all requests to the yahoo API return futures, using async
features.
Therefore, the functions need to be called from within another async
function with .await
or via functions like block_on
. The examples are based on the tokio
runtime applying the tokio-test
crate.
Use the blocking
feature to get the previous behavior back: i.e. yahoo_finance_api = {"version" = "1.0", features = ["blocking"]}
.
```rust use yahoofinanceapi as yahoo; use std::time::{Duration, UNIXEPOCH}; use time::OffsetDateTime; use tokiotest;
fn main() { let provider = yahoo::YahooConnector::new(); // get the latest quotes in 1 minute intervals let response = tokiotest::blockon(provider.getlatestquotes(\"AAPL\", \"1d\")).unwrap(); // extract just the latest valid quote summery // including timestamp,open,close,high,low,volume let quote = response.lastquote().unwrap(); let time: OffsetDateTime = OffsetDateTime::from(UNIXEPOCH + Duration::from_secs(quote.timestamp)); println!(\"At {} quote price of Apple was {}\", time, quote.close); } ```
```rust use yahoofinanceapi as yahoo; use std::time::{Duration, UNIXEPOCH}; use time::{macros::datetime, OffsetDateTime}; use tokiotest;
fn main() { let provider = yahoo::YahooConnector::new(); let start = datetime!(2020-1-1 0:00:00.00 UTC); let end = datetime!(2020-1-31 23:59:59.99 UTC); // returns historic quotes with daily interval let resp = tokiotest::blockon(provider.getquotehistory(\"AAPL\", start, end)).unwrap(); let quotes = resp.quotes().unwrap(); println!(\"Apple's quotes in January: {:?}\", quotes); } ```
Another method to retrieve a range of quotes is by requesting the quotes for a given period and lookup frequency. Here is an example retrieving the daily quotes for the last month: ```rust use yahoofinanceapi as yahoo; use std::time::{Duration, UNIXEPOCH}; use tokiotest;
fn main() { let provider = yahoo::YahooConnector::new(); let response = tokiotest::blockon(provider.getquoterange(\"AAPL\", \"1d\", \"1mo\")).unwrap(); let quotes = response.quotes().unwrap(); println!(\"Apple's quotes of the last month: {:?}\", quotes); } ```
```rust use yahoofinanceapi as yahoo; use tokio_test;
fn main() { let provider = yahoo::YahooConnector::new(); let resp = tokiotest::blockon(provider.search_ticker(\"Apple\")).unwrap();
let mut apple_found = false;
println!(\"All tickers found while searching for 'Apple':\");
for item in resp.quotes
{
println!(\"{}\", item.symbol)
}
}
``
Some fields like
longnameare only optional and will be replaced by default
values if missing (e.g. empty string). If you do not like this behavior,
use
searchtickeroptinstead which contains
Optionfields,
returning
None` if the field found missing in the response.
