1. Retrieving the Currency Pair List

Infoway maintains an updated list of 40 major currency pairs, including commonly traded pairs such as EUR/USD, GBP/USD, USD/JPY, and AUD/USD.

You can obtain this list in two ways:

Option 1 — Download from the Web Portal

Log in to your Infoway account and download the latest stock excel list file from the Downloads section at the right side of the dashboard.

Option 2 — Query via API

You can also retrieve the list programmatically through the HTTP Symbol List API. Refer to the GET /symbol-list documentation for usage details.

2. Query Methods

Infoway Forex API offers two primary data-access methods, optimized for different use cases:

Method	Ideal Use Case	Description
HTTP API	Scheduled or batch queries	Suitable for regular polling or historical data retrieval. Supports requests for fundamentals, historical candlestick data, real-time snapshots, and order book depth.
WebSocket Streaming	Low-latency, continuous updates	Best for low-latency updates and live data feeds. Allows continuous streaming of FX quotes, trades, and depth updates.

Both HTTP and WebSocket interfaces are subject to rate limits. See the Rate Limit Policy section for detailed constraints.
