Crypto Pay API Client for Rust 🦀

A type-safe Rust client for the Crypto Bot API with async support.

Features ✨

• 🔒 Complete type safety
• 🚀 Async support
• 💡 Comprehensive error handling
• 🛠 Built-in parameter validation
• 📦 Zero configuration
• 🔌 Webhook support
• 📚 Full API coverage
• 🧪 Complete test coverage

Quick Start 🚀

Add to your Cargo.toml:

[dependencies]
crypto-pay-api = "0.1.1"

Basic Example with tokio

use crypto_pay_api::prelude::*;

#[tokio::main]
async fn main() -> Result<(), CryptoBotError> {
    // Initialize client
    let client = CryptoBot::builder().api_token("YOUR_API_TOKEN").build()?;

    // Create an invoice
    let params = CreateInvoiceParamsBuilder::new()
        .asset(CryptoCurrencyCode::Ton)
        .amount(dec!(10.5))
        .description("Test payment".to_string())
        .build(&client)
        .await?;

    let invoice = client.create_invoice(&params).await?;
    println!("Payment URL: {}", invoice.pay_url);

    Ok(())
}

API Coverage 📋

Invoices

• ✅ Create invoice (create_invoice)
• ✅ Get invoices (get_invoices)
• ✅ Delete invoice (delete_invoice)

Transfers

• ✅ Transfer (transfer)
• ✅ Get transfers (get_transfers)

Checks

• ✅ Create check (create_check)
• ✅ Get checks (get_checks)
• ✅ Delete check (delete_check)

Other Features

• ✅ Get balance (get_balance)
• ✅ Get exchange rates (get_exchange_rates)
• ✅ Get currencies (get_currencies)
• ✅ Get app info (get_me)
• ✅ Get statistics (get_stats)

Advanced Usage 🔧

Webhook Handling

use crypto_pay_api::prelude::*;

#[tokio::main]
async fn main() -> Result<(), CryptoBotError> {
    let client = CryptoBot::builder().api_token("YOUR_API_TOKEN").build()?;
    let mut handler = client.webhook_handler(WebhookHandlerConfigBuilder::new().build());

    // Register payment callback
    handler.on_update(|update| async move {
        println!("Invoice paid: {:?}", update.payload);
        Ok(())
    });

    // Start webhook server
    // ... integrate with your web framework
}

See examples/axum_webhook.rs for an example using axum.

Custom Configuration

let client = CryptoBot::builder()
    .api_token("YOUR_API_TOKEN")
    .base_url("https://pay.crypt.bot/api")
    .timeout(Duration::from_secs(30))
    .build();

Error Handling ⚠️

The library provides detailed error types:

match client.get_balance().await {
    Ok(balances) => {
        for balance in balances {
            println!("{}: {}", balance.currency_code, balance.available);
        }
    }
    Err(CryptoBotError::ValidationError { kind, message, field }) => {
        eprintln!("Validation error: {} (field: {:?})", message, field);
    }
    Err(e) => eprintln!("Other error: {}", e),
}
