Usage

Basic Example

use polyte_gamma::Gamma;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let gamma = Gamma::new()?;

    // List active markets
    let markets = gamma.markets()
        .list()
        .active(true)
        .limit(10)
        .send()
        .await?;

    for market in markets {
        println!("{}: {}", market.question, market.volume);
    }

    Ok(())
}

Get Market by ID

let market = gamma.markets()
    .get("condition_id_here")
    .send()
    .await?;

println!("Market: {}", market.question);
println!("Volume: {}", market.volume);
println!("Liquidity: {}", market.liquidity);

List Series

let series = gamma.series()
    .list()
    .active(true)
    .send()
    .await?;

for s in series {
    println!("{} - {} events", s.title, s.events.len());
}

Get Tags

let tags = gamma.tags().list().send().await?;

for tag in tags {
    println!("{}: {}", tag.label, tag.slug);
}

let gamma = Gamma::builder()
    .base_url("https://gamma-api.polymarket.com")
    .timeout_ms(30_000)
    .pool_size(10)
    .build()?;
