API.getPrice(skin: string, options?: object, callback?: function)

Get price for a skin

const x = await API.getPrice('★ Bayonet');

> {
    id: '★ Bayonet',
    price: {
        type: 'euro',
        code: 'EUR',
        sign: '€',
        lowest: 135.44,
        median: 136.61,
    },
    volume: 8,
};

API.getPrices(skins: string[], options?: object, callback?: function)

Get prices for a array of skins

const x = await API.getPrices([ '★ Falchion Knife', '★ Karambit' ]);

> [
    {
        id: '★ Falchion Knife',
        price: {
            type: 'euro',
            code: 'EUR',
            sign: '€',
            lowest: 59.86,
            median: 57.50,
        },
        volume: 27,
    },
    {
        id: '★ Karambit',
        price: {
            type: 'euro',
            code: 'EUR',
            sign: '€',
            lowest: 215,
            median: 214.74,
        },
        volume: 6,
    }
];

Differences from the raw response of the original API:

Object Layout:

Info:

You can request the raw item by setting { raw: true } in the options. This is not recommended though.

Raw:

{
    success: true,
    lowest_price: "215,--€",
    volume: "6",
    median_price: "214,74€"
}

This Module:

{
    id: '★ Karambit',
    price: {
        type: 'euro',
        code: 'EUR',
        sign: '€',
        lowest: 215,
        median: 214.74,
    },
    volume: 6,
}

Prices:

The prices aren't available as a string, but rather split up in object properties with more precise information:

Example:

Price you would get from the API:

{
    lowest_price: "57,86€",
    median_price: "59,63€"
}

Price you get from this module:

{
    type: 'euro',
    code: 'EUR',
    sign: '€',
    lowest: 59.86,
    median: 57.74,
}

Volume:

The volume (of available skins) is a integer instead of a string

Async / Promises:

The examples are shown using await for simplicity - if you don't want to make your function async you can always use .catch().then() or a callback instead.

Example:

Async:

const item = await API.getPrice('★ Bayonet');

// do something with the <item>

Promise:

API.getPrice('★ Bayonet')
.catch((error) => {
    console.error(error);
})
.then((item) => {
    // do something with the <item>
});

Callback:

API.getPrice('★ Bayonet', (error, item) => {
    if (error) {
        return console.log(error);
    }

    // do something with the <item>
});
