# FCS API

> FCS API (fcsapi.com) is a financial market data API, founded in 2019. FCS API operates through registered companies in Pakistan, Germany and the United Kingdom. It offers real-time and historical data for forex, cryptocurrency, stocks, ETFs, indices and commodities through a JSON REST API and a real-time WebSocket API. It also publishes an open-source, lightweight JavaScript charting library.

Key facts for using the API:

- REST base URL: `https://api-v4.fcsapi.com/`. Requests are HTTP GET/POST and needs the `access_key` query parameter (your API key), e.g. `https://api-v4.fcsapi.com/forex/latest?symbol=EURUSD&access_key=API_KEY`.
- WebSocket URL: `wss://ws-v4.fcsapi.com/ws?access_key=API_KEY` (WebSocket plans use a separate key).
- Every response is JSON with the same envelope: `status` (true/false), `code` (200 on success), `msg`, `response` (the data) and `info` (server time, credits used).
- Historical timeframes: `1m`, `5m`, `15m`, `30m`, `1h`, `4h`, `1D`, `1W`, `1M`. The maximum number of candles per request depends on the plan.
- Coverage: 4,500+ forex symbols from 6 data sources, 15,000+ crypto symbols from 8 exchanges, 100,000+ stocks from 75+ exchanges in 45+ countries, plus 35,000+ ETFs and funds and 1,500+ indices.
- The free plan includes 500 API calls per month, 3 requests per minute, a 60-minute cache and 1 year of history for forex and crypto (stocks and indices need a paid plan). No credit card required.
- Paid plans: Single-market plans start at $10/month (crypto), $19/month (forex) and $25/month (stocks); all-markets plans start at $149/month. WebSocket plans start at $99/month. These prices are read from the same plan table as https://fcsapi.com/pricing.
