# Market API Rust example

> End-to-end Rust example: call the Velora Market API to quote 1 ETH → USDC via reqwest.

A minimal Rust program that calls `GET /prices` and prints the quoted `destAmount`. Uses `reqwest` with `tokio`.

## File tree

```text theme={null}
my-app/
├─ Cargo.toml
└─ src/
   └─ main.rs
```

## Install

```bash theme={null}
cargo new my-app
cd my-app
cargo add reqwest --features json
cargo add tokio --features full
cargo add serde --features derive
```

## `src/main.rs`

```rust theme={null}
use serde::Deserialize;

#[derive(Deserialize, Debug)]
struct PriceRoute {
    #[serde(rename = "destAmount")]
    dest_amount: String,
    #[serde(rename = "gasCostUSD")]
    gas_cost_usd: String,
}

#[derive(Deserialize, Debug)]
struct PricesResponse {
    #[serde(rename = "priceRoute")]
    price_route: PriceRoute,
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let params = [
        ("srcToken",     "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE"), // ETH
        ("destToken",    "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48"), // USDC
        ("amount",       "1000000000000000000"),                       // 1 ETH
        ("srcDecimals",  "18"),
        ("destDecimals", "6"),
        ("side",         "SELL"),
        ("network",      "1"),
        ("userAddress",  "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"),
        ("partner",      "my-app-name"),
        ("version",      "6.2"),
    ];

    let res = reqwest::Client::new()
        .get("https://api.velora.xyz/prices")
        .query(&params)
        .send()
        .await?
        .error_for_status()?
        .json::<PricesResponse>()
        .await?;

    println!("destAmount: {}", res.price_route.dest_amount);
    println!("gasCostUSD: {}", res.price_route.gas_cost_usd);

    Ok(())
}
```

## Run it

```bash theme={null}
cargo run
```

You should see the quoted `destAmount` (USDC, 6 decimals) and `gasCostUSD` printed.

## Next: build the transaction

Feed the `priceRoute` into `POST /transactions/:chainId` to get ready-to-broadcast calldata. See [Market API → How it works](/market/how-it-works).
