Frequently Asked Questions

RealMarketAPI is a market data platform that provides realtime and historical OHLC data through REST APIs and WebSocket streams for metals, forex, crypto, commodities, and indices.

You can access symbols including XAUUSD, XAGUSD, USDJPY, BTCUSD, ETHUSD, XRPUSD, USOIL, UKOIL, US500, and US30. Available symbols may vary by plan.

Supported timeframes are M5, M15, H1, H4, and D1. Not every plan includes every timeframe, so check your current plan limits.

Requests use your apiKey as a query parameter in endpoint URLs. Keep your apiKey private and rotate it immediately if you suspect exposure.

/api/v1/price returns the latest candle for a symbol and timeframe, while /api/v1/history returns paginated historical candle data between startTime and endTime.

Use WebSocket for continuous realtime updates and low-latency interfaces. Use REST when you need on-demand snapshots, historical lookups, or server-side jobs.

Yes. Each plan has request-per-minute and monthly request limits. If exceeded, the API may return a 429 status code until your quota window resets.

Use pageNumber and pageSize on /api/v1/history. Responses include TotalCount, CurrentPage, TotalPages, and PageSize to help iterate through the dataset.

Common statuses include 400 (validation error), 401 (unauthorised), 403 (forbidden), 429 (rate limited), and 500 (server error). Use TraceId when contacting support.

Commercial use depends on your plan. Starter/Pro/Business/Enterprise plans are designed for production usage, whilst Free is intended for testing and learning.

Response times vary by plan and issue type. Priority and enterprise tiers receive faster support handling, especially for production-impact incidents.

You can upgrade from the pricing page or contact the sales team for custom limits, dedicated infrastructure, private endpoints, and enterprise SLA options.
