Currency Exchange — entry 005 of 18
1Forge
1Forge streams live bid/ask quotes for 700+ forex and cryptocurrency pairs through a REST API (quotes, symbols, market_status, convert, quota endpoints) plus a low-latency WebSocket feed reserved for paid plans, with tick updates reported at up to 200+ per second during active markets. It is a smaller, independently run alternative to the APILayer-owned entries in this category, requiring a free-signup API key passed as a query parameter.
