Esports Odds API: CS2, LoL & Dota 2 Betting Data from 350+ Bookmakers

Q: Which esports titles are covered?

OddsPapi covers Counter-Strike 2 (CS2), League of Legends, Dota 2, Valorant, Call of Duty, Rocket League, Overwatch, Rainbow Six, StarCraft, Arena of Valor, King of Glory, and Honor of Kings. Each title has its own sport ID and tournament structure.

Q: Does the API include Pinnacle esports odds?

Yes. OddsPapi includes Pinnacle odds for esports alongside esports specialists like GG.BET, Thunderpick, and Betway. Pinnacle odds are the industry benchmark for sharp pricing on CS2, LoL, and Dota 2 matches.

Q: What is the difference between an esports odds feed and an API?

An odds feed typically refers to a real-time push-based data stream (WebSocket) that delivers odds updates as they happen. An API is a request-response interface where you poll for data. OddsPapi provides both: a REST API for polling (free tier) and a WebSocket feed for real-time streaming (Pro tier).

Q: How fast are esports odds updates?

Via the REST API, odds are updated within seconds of bookmaker changes. Via the WebSocket feed (Pro tier), updates are pushed in sub-second intervals. For pre-match analysis and line shopping, the REST API is sufficient. For live betting automation, use the WebSocket feed.

Q: Can I get BLAST Premier or IEM odds through the API?

Yes. Major CS2 tournaments like BLAST Premier, IEM, ESL Pro League, and PGL Majors are covered with odds from 10-14 bookmakers per fixture. Use sportId=17 and filter by tournament to find specific event fixtures.

How To Guides December 8, 2025

Why Most Esports APIs Fall Short

If you’ve tried to build anything with esports odds data, you already know the problem. The enterprise providers — Sportradar, PandaScore, Abios — charge $2,000-$10,000/month and lock you into annual contracts. The generic sports APIs cover 5-10 bookmakers for esports, maybe Bet365 and a few soft books. Neither option gives you what actually matters: sharp bookmaker odds from Pinnacle alongside esports specialists like GG.BET and Thunderpick, all in one feed.

OddsPapi fills that gap. 350+ bookmakers, including sharp books (Pinnacle, Singbet), crypto books (1xBet, Stake), and esports-native books (GG.BET, Thunderpick, Betway) — all through one REST API with a free tier. No enterprise sales call. No scraping. JSON in, odds out.

This guide covers everything: what’s covered, how to fetch it, and how it compares to every alternative.

Esports Odds Feed: What’s Covered

OddsPapi treats each esports title as its own sport, with dedicated sport IDs, tournament structures, and market types. Here’s the coverage breakdown:

Game	Sport ID	Example Tournaments	Markets
Counter-Strike 2	17	PGL Major, ESL Pro League, BLAST Premier, IEM	Match Winner, Map Winner, Map Handicap, Total Maps, Correct Score
League of Legends	18	Worlds, LEC, LCS, LCK, LPL, CBLOL	Match Winner, Map Winner, Map Handicap, Total Maps
Dota 2	16	The International, DreamLeague, ESL One, DPC	Match Winner, Map Winner, Map Handicap, Total Maps
Valorant	61	VCT Champions Tour, Game Changers, EMEA Clash	Match Winner, Map Winner, Map Handicap
Call of Duty	56	CDL Major, Call of Duty League	Match Winner, Map Markets
Rocket League	59	RLCS, Rocket League Championship Series	Match Winner, Map Markets

Key Bookmakers for Esports

The bookmakers that matter for esports aren’t the same ones that matter for NFL or Premier League. Here’s who you get through OddsPapi:

Bookmaker	Type	Why It Matters
Pinnacle	Sharp	The benchmark line for esports. Lowest vig, sharpest market.
GG.BET	Esports Specialist	Deepest esports market coverage. Player props, round markets.
Betway	Major Soft	Heavy esports sponsorship (formerly Betway Esports). Wide coverage.
1xBet	Crypto/Global	Covers tier-2 and tier-3 tournaments most books ignore.
Thunderpick	Crypto Esports	Esports-first book. CS2 and Dota 2 specialist markets.
Bet365	Soft Global	Largest soft book. Mainstream esports coverage.
Stake	Crypto	Major CS2 sponsor. Fast odds updates for live esports.

REST API vs WebSocket

OddsPapi offers two ways to consume esports odds data:

Method	Use Case	Update Speed	Tier
REST API	Pre-match analysis, line shopping, model building	Seconds (poll-based)	Free
WebSocket	Live betting bots, real-time dashboards, arb detection	Sub-second (push-based)	Pro

For pre-match esports data, the REST API on the free tier is all you need. If you’re building something that reacts to live odds movements during a CS2 match, the WebSocket feed on the Pro tier pushes updates as they happen — no polling delay.

Esports Betting API Comparison (2026)

Here’s how OddsPapi stacks up against the alternatives for esports odds data specifically:

Feature	OddsPapi	PandaScore	Abios	The Odds API
Esports Bookmakers	14+ per fixture (majors)	N/A (stats only)	N/A (stats only)	5-10
Total Bookmakers	350+	0 (no odds)	0 (no odds)	~40
Sharp Books (Pinnacle)	Yes	No	No	Yes
Esports Specialists	GG.BET, Thunderpick, Stake	N/A	N/A	No
Games Covered (Odds)	6+ titles	20+ (stats only)	30+ (stats only)	4-5
Match Stats/Scores	No	Yes (deep)	Yes (deep)	No
Historical Odds	Free tier	N/A	N/A	Paid only
WebSocket	Pro tier	Yes	Yes	No
Free Tier	Yes (350+ books)	No	No	Yes (~40 books)
Price	Free – $99/mo	$2,000+/mo	Enterprise	Free – $199/mo

The honest take: If you need match stats, player performance data, or in-game events (kills, objectives, round scores), PandaScore and Abios are built for that — but they don’t provide odds data. If you need odds from multiple bookmakers to build line shopping tools, arb scanners, or predictive models, OddsPapi is the only API that covers esports-specialist bookmakers on a free tier.

Esports Markets & Odds Types

Esports markets follow a different structure than traditional sports. The core unit is a map (or game/round depending on the title), not a half or quarter. Here are the verified market IDs for esports:

Market	Market ID	Outcomes	Available For
Match Winner	171	171 (Team 1), 172 (Team 2)	All titles
Map 1 Winner	173	173 (Team 1), 174 (Team 2)	CS2, LoL, Dota 2, Valorant
Map 2 Winner	175	175 (Team 1), 176 (Team 2)	CS2, LoL, Dota 2, Valorant
Map 3 Winner	177	177 (Team 1), 178 (Team 2)	CS2, LoL, Dota 2 (Bo3+)
Correct Score 2-0	1721	1721 (Team 1), 1722 (Team 2)	CS2, LoL, Dota 2
Map 1 Handicap	1725	1725 (Team 1), 1726 (Team 2)	CS2
Total Maps Over	1737	1737 (Over), 1738 (Under)	CS2, LoL, Dota 2
Map 1 Total Over	1741	1741 (Over), 1742 (Under)	CS2

Note: Market availability varies by bookmaker and tournament tier. Pinnacle and GG.BET typically offer the widest range of esports markets. Smaller bookmakers may only price the Match Winner (171) market.

Python Tutorial: Fetch Esports Odds in 5 Minutes

Everything below uses the free tier. No credit card required.

Step 1: Get Your API Key

Sign up at oddspapi.io and grab your API key from the dashboard. Authentication is via query parameter — no headers, no OAuth.

Step 2: Discover Esports Sports

import requests

API_KEY = "YOUR_API_KEY"
BASE = "https://api.oddspapi.io/v4"

# List all sports — filter for esports
response = requests.get(f"{BASE}/sports", params={"apiKey": API_KEY})
sports = response.json()

esports = [s for s in sports if s["slug"].startswith("esport")]
for s in esports:
    print(f"{s['sportId']:>3}  {s['sportName']}")

# Output:
# 16  ESport Dota
# 17  ESport Counter-Strike
# 18  ESport League of Legends
# 56  ESport Call of Duty
# 57  ESport Overwatch
# 58  ESport Rainbow Six
# 59  ESport Rocket League
# 60  ESport StarCraft
# 61  ESport Valorant
# 62  ESport Arena of Valor
# 63  ESport King of Glory
# 65  ESport Honor of Kings

Step 3: Find CS2 Matches with Odds

# Fetch CS2 fixtures for the next 7 days
from datetime import datetime, timedelta

today = datetime.now().strftime("%Y-%m-%d")
week_out = (datetime.now() + timedelta(days=7)).strftime("%Y-%m-%d")

response = requests.get(f"{BASE}/fixtures", params={
    "apiKey": API_KEY,
    "sportId": 17,          # CS2
    "from": today,
    "to": week_out,
    "hasOdds": True          # Only fixtures with odds
})
fixtures = response.json()

print(f"CS2 fixtures with odds: {len(fixtures)}\n")
for f in fixtures[:5]:
    print(f"{f['participant1Name']} vs {f['participant2Name']}")
    print(f"  Tournament: {f['tournamentName']}")
    print(f"  Fixture ID: {f['fixtureId']}")
    print(f"  Start: {f['startTime']}\n")

Step 4: Compare Odds Across Bookmakers

# Get odds for a specific fixture
fixture_id = fixtures[0]["fixtureId"]

response = requests.get(f"{BASE}/odds", params={
    "apiKey": API_KEY,
    "fixtureId": fixture_id
})
data = response.json()

print(f"{data.get('participant1Name', 'Team 1')} vs {data.get('participant2Name', 'Team 2')}\n")
print(f"{'Bookmaker':<20} {'Team 1':>8} {'Team 2':>8}")
print("-" * 38)

for slug, bk_data in data["bookmakerOdds"].items():
    markets = bk_data.get("markets", {})
    if "171" in markets:  # Match Winner market
        outcomes = markets["171"]["outcomes"]
        p1 = outcomes.get("171", {}).get("players", {}).get("0", {}).get("price", "—")
        p2 = outcomes.get("172", {}).get("players", {}).get("0", {}).get("price", "—")
        print(f"{slug:<20} {p1:>8} {p2:>8}")

This prints something like:

Parivision vs Team Vitality

Bookmaker                Team 1   Team 2
--------------------------------------
pinnacle                  1.303     3.44
betway                     4.40     1.17
vbet                       1.33     3.10
paddypower                 1.30     3.50
roobet                     1.35     2.94
bcgame                     1.33     3.10

Step 5: Fetch Odds for Multiple Esports

# Scan all esports titles for upcoming matches
ESPORTS = {
    16: "Dota 2",
    17: "CS2",
    18: "League of Legends",
    61: "Valorant",
}

import time

for sport_id, name in ESPORTS.items():
    response = requests.get(f"{BASE}/fixtures", params={
        "apiKey": API_KEY,
        "sportId": sport_id,
        "from": today,
        "to": week_out,
        "hasOdds": True
    })
    fixtures = response.json()
    print(f"{name}: {len(fixtures)} fixtures with odds")
    time.sleep(2)  # Respect rate limits

# Output (example):
# Dota 2: 7 fixtures with odds
# CS2: 27 fixtures with odds
# League of Legends: 25 fixtures with odds
# Valorant: 10 fixtures with odds

Historical Esports Odds: Free Backtesting Data

Most APIs charge extra for historical data. OddsPapi includes it on the free tier — every odds movement, timestamped, for every bookmaker that priced the match.

This is the data you need to backtest esports betting models: Did Pinnacle’s opening line predict the winner? How much did odds move after map vetoes? Where did the value sit before the market corrected?

# Fetch historical odds for a CS2 match
fixture_id = "id1704591169167084"  # PGL Major match

response = requests.get(f"{BASE}/historical-odds", params={
    "apiKey": API_KEY,
    "fixtureId": fixture_id,
    "bookmakers": "pinnacle",    # Up to 3 bookmakers per request
    "marketId": 171              # Match Winner
})
data = response.json()

# Historical odds are timestamped arrays
pinnacle = data["bookmakers"]["pinnacle"]["markets"]["171"]
team1_history = pinnacle["outcomes"]["171"]["players"]["0"]

print(f"Pinnacle odds history ({len(team1_history)} snapshots):\n")
for snap in team1_history[:5]:
    print(f"  {snap['createdAt'][:19]}  →  {snap['price']}")

Output:

Pinnacle odds history (7 snapshots):

  2026-02-22T04:18:46  →  1.303
  2026-02-22T04:18:41  →  1.307
  2026-02-22T04:17:52  →  1.3
  2026-02-22T04:17:52  →  1.317
  2026-02-22T04:17:51  →  1.308

You get the full line movement history — from opening price to kickoff — for free. Compare this to The Odds API, where historical data requires a paid plan, or PandaScore, which doesn’t provide odds data at all.
