Usage

Creating a Client

First, import and create a client instance. You can optionally pass in configuration options.

import { createClient } from '@anypay/prices-client';

const client = createClient({
  http_api_url: 'https://prices.anypayx.com', // Optional custom API URL
  websocket_api_url: 'wss://prices.anypayx.com', // Optional custom WebSocket URL
  token: 'your_api_token_here', // Optional API token for authenticated requests
});

Subscribing to Price Updates

To listen for real-time updates on prices:

client.subscribeToPricesUpdates();

client.on('price/updated', (price) => {
  console.log('Price updated', price);
});

client.on('websocket.error', (err) => {
  console.error('WebSocket error', err);
});

client.on('websocket.open', () => {
  console.log('WebSocket open');
});

client.on('websocket.message', (data) => {
  console.log(data);
});

Unsubscribing from Price Updates

To stop receiving price updates:

client.unsubscribeFromPricesUpdates();

Fetching Prices and Conversions

Fetch current prices:

async function fetchPrices() {
  const prices = await client.listPrices();
  console.log(prices);
}
fetchPrices();

Convert one currency to another:

async function convertCurrency() {
  const conversion = await client.convertPrice({
    base: 'USD',
    value: 1000,
    quote: 'BTC'
  });
  console.log(conversion);
}
convertCurrency();
