FIX API
Market Data - FIX API
Financial Information eXchange (FIX) protocol is an electronic communications protocol initiated in 1992 for international real-time exchange of information related to the securities transactions and markets. You can use it to receive real-time market data from us and it's an alternative to WebSocket protocol.
If you don't have experience with FIX protocol, consider using a much simpler to implement REST or WebSocket API.

Our production endpoint configuration parameters:
| Parameter | Value |
|---|---|
| Hostname | fix.coinapi.io |
| Port Unecnrypted | 3302 |
| Port TLS/SSL | 3303 |
| Protocol version | FIX.4.4 (XML FIX Specification can be downloaded here: FIX44.xml) |
| Gateway timezone | UTC |
We recommend using our SDK or listed client libraries depending on your language requirements:
Security
Stunnel configuation:
[COINAPI]
client = yes
accept = 3302
connect = fix.coinapi.io:3303
verify = 2
Communication with our FIX gateway is secured by TLS protocol if you are using the encrypted port. If your FIX protocol implementation does not support establishing a connection over a secure channel, you must use a proxy between your client and our FIX gateway to unbundle encryption or use the unencrypted port. We recommend stunnel as a proxy if a secure connection can't be established directly from your client and you can't allow unencrypted traffic.
You should assume that we are always providing certificates signed by the Trusted Certification Authority.
