Futures Push Feed API Documentation

Requirement

You need an Enterprise plan to use the OddsBlaze push feed.

Description

This endpoint streams real-time futures data by SSE push feed.

API Endpoint

https://futures.stream.oddsblaze.com/

Parameters

key (required)

Your OddsBlaze API key.

sportsbook

The sportsbook id (e.g., draftkings or betmgm). Separate multiple sportsbooks with commas (e.g., draftkings,betmgm).

league

The league id (e.g., nfl or mlb). Separate multiple leagues with commas (e.g., nfl,mlb,nba).

Last-Event-ID

When reconnecting, provide the Last-Event-ID header (or last-event-id URL parameter) with the most recent event id (e.g., 1758600171703-0). This ensures the feed resumes from the point where the connection was interrupted, preventing missed updates.

Connections

A single connection can stream all sportsbooks for one league or all leagues for one sportsbook. If your request includes too many league or sportsbook parameters, the server will return an error:

{"message": "Missing league or sportsbook"}

{"message": "Too many leagues or sportsbooks"}

{"message": "Too many leagues"}

{"message": "Too many sportsbooks"}

{"message": "Too many connections"}
