fastFOREX API vs ExchangeRate-API
A well-run budget option: $10 for 30k hourly calls. But its fastest plan is 5-minute updates — ours starts at 60 seconds.
fastFOREX API vs CurrencyFreaks
Broad coverage and data to 1984 — but 60-second updates cost $99.99, and there's no bid/ask, OHLC or streaming.
fastFOREX API vs CurrencyAPI
Good value at $39.99 for 600k 60-second calls, with a hosted MCP server — but midpoint-only: no bid/ask, OHLC or streaming, and metals stop at the four precious ones.
fastFOREX API vs XE
The big brand — from $799/yr for 10,000 daily-rate calls, with live rates as a paid add-on. Compare the maths.
fastFOREX API vs ExchangeRatesAPI.io
Another APILayer brand with the familiar $14.99-for-10k-hourly formula — 60-second data costs $99.99.
