Crate polymarket_client 

Unified Polymarket Rust SDK.

Modeled after the official TypeScript SDK (@polymarket/client).

Clients

• PublicClient — read-only discovery, market data, and (with account) portfolio reads
• [SecureClient] — authenticated trading, notifications, rewards, CTF wallet ops, and user websockets

Feature flags

Feature	Enables
(default)	HTTP discovery + CLOB market data
account	Data API reads on PublicClient
websockets	Realtime subscribe() on PublicClient
secure	account + websockets + [SecureClient] trading and wallet ops

Quickstart

use polymarket_client::{Environment, PublicClient};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = PublicClient::new(Environment::production());
    let mut paginator = client.list_markets(polymarket_client::ListMarketsRequest {
        closed: Some(false),
        page_size: Some(5),
        ..Default::default()
    })?;
    let page = paginator.first_page().await?;
    for market in &page.items {
        println!("{}: {}", market.id, market.question.as_deref().unwrap_or(""));
    }
    Ok(())
}

Realtime (websockets)

use futures::StreamExt as _;
use polymarket_client::{Environment, MarketSubscription, PublicClient, SubscriptionSpec};

let client = PublicClient::new(Environment::production());
let mut handle = client.subscribe(vec![SubscriptionSpec::Market(MarketSubscription {
    token_ids: vec!["123".into()],
    custom_feature_enabled: false,
})])?;
if let Some(Ok(event)) = handle.next().await {
    println!("{event:?}");
}
handle.close();
