  title: 1Forge Forex Data API
  description: |-
    1Forge provides real-time bid and ask quote data for 700+ forex and cryptocurrency
    currency pairs, delivered with FIX-grade speed over a simple JSON REST API. The
    REST surface covers five operations: list available symbols, fetch quotes for one
    or more pairs, convert a quantity between two currencies, check whether the market
    is currently open, and inspect remaining quota for the calling API key.

    1Forge connects directly to brokers and liquidity providers and serves traffic from
    four global edge locations (Oregon, Virginia, Taiwan, Belgium). Streaming over
    WebSocket is documented separately in `asyncapi/1forge-forex-stream-asyncapi.yml`.
