FalconX API Documentation
Five REST APIs, each with its own reference below. They share a signing
scheme — HMAC-SHA256 over
timestamp + method + requestPath + body — but not the same
header set, so start with the Authentication section of whichever one you
are integrating.
Spot
Institutional access to FalconX liquidity: request a price, execute against it, and manage the balance it settles to. Firm quotes over REST, continuous streams over WebSocket.
REST · WebSocket · FIXDMA
Direct market access trades connected exchange venues against FalconX credit rather than pre-funded balances. This API is how you keep the right balance in the right subaccount without logging in.
REST · v2Credit
Borrow against your FalconX collateral and monitor the margin health of the pool you borrow from. Scoped to the pool your API key belongs to.
REST · v1Reporting
Cross-product reporting behind FalconX 360, as an API. Balance detail for every asset in every wallet on every venue, each with a USD counterpart, per-instrument position detail, your order history — whichever product placed the order — and transfer activity across products.
REST · v1Derivatives
Report on the options and total-return swaps booked with FalconX, whether traded with the desk or electronically: open contracts with their marks, margin per token, the fills behind a trade, and scheduled or settled cash flows. Options RFQ and TRS trading docs are coming soon.
REST · v1These pages are a read-only reference — there is no request runner, so call the endpoints from your own client. Questions? [email protected]
