OddsBlaze API Review 2026

OddsBlaze is a real-time sports odds API focused on US sportsbooks. It covers 24+ books (DraftKings, FanDuel, BetMGM, Caesars, Bet365, Circa, Bovada, and others) with sub-second latency and a standardized data format across all sources. The headline feature is same game parlay (SGP) pricing, which most competitors do not offer at all.

The product sits at the intersection of speed and depth. You get main lines, player props, alternate markets, futures, and SGP odds from the same API, delivered through either a REST pull or an SSE push feed. OddsBlaze also ships built-in arbitrage detection and closing line value (CLV) tracking, so the tooling that usually lives in your own code comes bundled with the data.

OddsBlaze lists dedicated pages for 24 sportsbooks, including regulated US books and offshore operators. The sport coverage spans 40+ leagues:

• US majors: NFL, NBA, MLB, NHL, WNBA, NCAAF, NCAAB, NCAA Baseball, MLS.
• Soccer: Premier League, La Liga, Bundesliga, Serie A, Ligue 1, Champions League, Europa League, MLS, World Cup.
• Tennis: ATP, WTA, ITF, UTR, Challenger.
• Other: Golf (PGA), MMA/UFC, CFL, table tennis, Korean Baseball.

Market types include moneylines, spreads, totals, player props, alternates, and futures. The differentiator is the SGP endpoint, which returns same game parlay prices directly from the sportsbooks. SGP data is difficult to source because books generate these prices dynamically per combination. OddsBlaze is one of very few APIs that expose it as a structured feed. If your product needs parlay pricing, that alone narrows the field to OddsBlaze and a handful of others. For general sports odds API coverage, the directory has the full comparison.

OddsBlaze offers two delivery methods. The REST API returns JSON on request, and the SSE (Server-Sent Events) push feed streams updates as they happen. SSE push is only available on the Enterprise tier, so most users start with REST polling.

The site claims sub-second latency across all sportsbooks and markets. Rate limits are per-minute rather than per-day: Plan 1 allows 300 requests per minute, Plan 2 allows 2,000 requests per minute. SGP requests have their own separate limits (30/min on Plan 1, 200/min on Plan 2). That separation matters because SGP queries are heavier and you do not want them eating into your main-line budget.

Data comes in a consistent schema regardless of the source sportsbook, so you write one parser for all 24+ books. The standardized format also covers deeplinks, which let you send users directly to the relevant bet slip on each sportsbook's app or site.

Published pricing starts at $299 per month. There is no free tier, though a trial is available on request.

• Plan 1 ($299/mo): 300 requests/minute, 30 SGP requests/minute, same game parlay support, Rewind (historical data), CLV, and OLV (opening line value). No push feed.
• Plan 2 ($999/mo): 2,000 requests/minute, 200 SGP requests/minute, all Plan 1 features plus line movement tracking. No push feed.
• Enterprise (custom): Custom request limits, custom SGP limits, SSE push feed connections, and priority support.

Both published plans include historical data (Rewind), CLV, and OLV at no extra charge. The jump from $299 to $999 buys significantly higher throughput and line movement data. Push feed delivery requires the Enterprise tier, which means a sales conversation. Payment runs through Stripe.

OddsBlaze has no free plan, but a trial key is one short form away. Hit "Try It Free Now" on the OddsBlaze home page, enter a name and an email (company is optional), and the site emails you a trial key. The form asks for no card. The site doesn't say how long the trial runs, and its terms allow one trial per person (checked November 2026).

To pay, pick Plan 1 or Plan 2 on the plans page, which checks out through Stripe. Enterprise starts with an email to help@oddsblaze.com. Each keyed endpoint takes the key the same way, as a key query parameter: https://odds.oddsblaze.com/?key=your_key. The docs list no header option, so keep those URLs out of shared logs. The "Manage Subscription" link in the site menu opens the billing portal.

This sample asks the odds endpoint for DraftKings NBA moneylines. The host, the key parameter and the field names come from the docs, checked November 2026.

import os

import requests

resp = requests.get(
    "https://odds.oddsblaze.com/",
    params={
        "key": os.environ["ODDSBLAZE_API_KEY"],
        "sportsbook": "draftkings",
        "league": "nba",
        "market": "moneyline",
    },
    timeout=10,
)
resp.raise_for_status()

for event in resp.json()["events"]:
    teams = event["teams"]
    prices = [(o["name"], o["price"]) for o in event["odds"]]
    print(teams["away"]["name"], "at", teams["home"]["name"], event["date"], prices)

The body carries updated, the league and sportsbook objects and an events list. Each event has teams, a date, a live flag and an odds list. An entry there holds the market, the selection name, a price in American odds and links to the bet slip; add price=decimal to the query for decimal odds. An entry's sgp token, when set, is what you POST to https://draftkings.sgp.oddsblaze.com/ to price a same game parlay.

The plan section above lists the per-minute caps for Plan 1 and Plan 2. Enterprise sets its own request, SGP and push-feed connection limits. On the push feed at stream.oddsblaze.com, one connection streams every book for one league or every league for one book; ask for more and the server answers with an error such as Too many connections. Reconnect with a Last-Event-ID header and the feed picks up where it dropped. The docs don't describe what a request over the per-minute cap returns (checked November 2026).

The OddsBlaze docs give each endpoint its own page with example URLs and a sample response. Two endpoints work as a status check: status.oddsblaze.com/odds reports a status per book and league, such as Healthy, with event, odds and props counts, and polled.oddsblaze.com/odds says when each book was last polled. We found no official SDK, OpenAPI file or changelog, and a few lines of requests cover it. Support runs through help@oddsblaze.com.

The product maps to a specific set of use cases where speed and market depth overlap:

• Arbitrage and middling tools that need real-time prices across many US books. OddsBlaze includes a built-in arbitrage finder in addition to the raw feed.
• Same game parlay products that surface correlated bets or parlay builders to end users. The SGP endpoint is the obvious draw here.
• CLV tracking and line grading for bettors who measure their edge against closing numbers.
• Odds comparison sites that need standardized data and deeplinks across US sportsbooks.

The $299 starting price and the lack of a free tier mean this is aimed at teams and serious builders, not weekend projects. If you only need a few books and basic moneylines for now, a cheaper option from the free odds API list will get you started, and you can add OddsBlaze when the build needs more. OddsBlaze earns its price when you need SGP data, sub-second updates, or the built-in arbitrage tooling.

Most broad aggregators (300+ bookmakers, global coverage) optimize for breadth. OddsBlaze optimizes for depth on a narrower set of US books. You get fewer sources but more market types per source, including SGP and alternate lines that aggregators often miss.

The trade-off is geographic scope. OddsBlaze does not cover international sharp books like Pinnacle or SBOBET (though the directory data marks Pinnacle coverage as present, the site's sportsbook list is US-focused). It also does not cover exchanges or crypto books. If your model needs a sharp anchor or global reach, pair OddsBlaze with a Pinnacle-specific feed or a broader aggregator from the directory. If your product lives inside the US regulated market, the depth here is hard to match.

OddsBlaze is a speed-and-depth play for the US sportsbook market. The SGP endpoint, built-in arbitrage detection, and historical CLV data set it apart from generic odds feeds. The pricing ($299 to $999/mo, enterprise above that) puts it firmly in professional territory.

The gaps are clear: no free tier, no push feed below enterprise, and limited international coverage. If international books matter to your build, pair it with a general aggregator from the directory. If you need fast US odds with parlay pricing and are willing to pay for it, OddsBlaze delivers on that promise. Request a trial and benchmark the latency against your own requirements before committing.

What stood out when we vetted OddsBlaze for the directory:

• <1 Second latency for realtime odds with Websocket support
• SGP Odds endpoints exclusive to the OddsBlaze platform
• Historical CLV, OLV, & line movement

Industry leading latency, SGP endpoints, and extra endpoints like Arbitrage & Consensus Odds.
