spectracost

AI cost observability SDK for Rust. Wrap your OpenAI or Anthropic calls with one method and every request is tracked automatically.

cargo add spectracost tokio --features=tokio/full

OpenAI

use spectracost::{Spectracost, Options, openai::ChatRequest};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let sc = Spectracost::new(Options {
        api_key: "sprc_...".into(),
        openai_api_key: Some("sk-...".into()),
        team: Some("search".into()),
        ..Default::default()
    });

    let response = sc.openai_chat(ChatRequest {
        model: "gpt-4o-mini".into(),
        messages: vec![
            ("user".into(), "Say hello!".into()).into(),
        ],
        max_tokens: Some(50),
    }).await?;

    println!("{}", response.first_message().unwrap_or_default());
    Ok(())
}

Anthropic

use spectracost::{Spectracost, Options, anthropic::MessagesRequest};

let sc = Spectracost::new(Options {
    api_key: "sprc_...".into(),
    anthropic_api_key: Some("sk-ant-...".into()),
    ..Default::default()
});

let response = sc.anthropic_messages(MessagesRequest {
    model: "claude-haiku-4-5-20251001".into(),
    max_tokens: 50,
    messages: vec![
        ("user".into(), "Say hello!".into()).into(),
    ],
}).await?;
