FIX API access to SiftingIO delivers our aggregated fair price over a standard FIX 4.4 session for crypto, forex, and commodities and metals, into your OMS or trading stack. Market data only, no order entry. SiftingIO is a market data provider, not a broker, and takes no orders. FIX 5.0 SP2 is available on request for enterprise.
Subscribe once and receive SiftingIO’s consensus fair price for crypto, forex, and commodities and metals, with the same data model as our REST and WebSocket products. The wire-level session and message detail live in the FIX API documentation.
Receive reference prices and quote fields for subscribed instruments, with an initial snapshot followed by incremental updates. Field meaning and available sizes depend on the asset class; they do not represent executable liquidity.
The fair price is a consensus derived across multiple venues, de-duplicated and normalized, so you consume one reference price per instrument instead of reconciling many raw feeds yourself.
Subscribe to crypto from both centralized and on-chain venues, forex, and commodities and metals in a single session. Stocks are not offered over FIX.
Instruments use SiftingIO canonical codes in the Symbol field, for example BTCUSD, GBPUSD, and XAUUSD. Discover the available instrument set with a SecurityList request, or take the mapping sheet during onboarding.
The FIX feed uses the same underlying reference-price data as the REST and WebSocket products. Compare the same instrument and timestamp when reconciling values across transports.
Logon, heartbeat, sequence numbers, and gap-fill recovery follow the FIX standard. On reconnect you receive a fresh snapshot rather than a replay of stale quotes.
FIX is an enterprise transport for consuming prices, not a route to trade. It is provisioned per account and certified against your system before it goes live.
SiftingIO is a market data provider, not a broker. The FIX session delivers reference prices and quotes. It accepts no orders and routes no executions: there is no order entry and no execution report to act on through us.
FIX is delivered as an enterprise transport over TCP with TLS, on IP-allowlisted sessions. Specific latency, throughput, and failover terms are set per engagement, so talk to us for the numbers that apply to your setup.
Access is provisioned per account: we issue your SenderCompID and TargetCompID, you connect from allowlisted IP addresses to a test session, we run a conformance pass against your system, then promote you to production.
Send a MarketDataRequest for one or more symbols and receive a snapshot followed by incremental updates. The full session, symbology, and message reference is in the FIX API documentation.

FIX 4.4 is the standard offering. FIX 5.0 SP2 is available on request for enterprise accounts.
SiftingIO's aggregated reference prices, bid and ask fields, and available size fields. You receive a snapshot on subscribe and incremental updates thereafter. Field meaning depends on the asset class: FX and metals prices can be quote midpoints, while FX and DEX quote or size fields can be derived. These are reference data, not a record of individual executions or executable liquidity.
It is a consensus price built across multiple venues, then de-duplicated and normalized into one reference value per instrument. It is the same fair price the REST and WebSocket products return.
