Tennis Odds API

Tennis does not fit a team-sports data model, and most odds APIs make you work around that. Ours handles it directly: matches are events, the two players occupy the participant slots, and sets work as periods. If you already consume our NFL or NBA data, tennis arrives in the same shape.

How Tennis Data Is Structured

This is the part worth understanding before you integrate, because it is where tennis differs from the team sports in the API.

Players, not teams. Tennis tours are configured as single-participant, so the home and away slots on an event hold the two players rather than clubs. The labels carry no venue meaning — there is no home advantage in a neutral-site draw — but the event shape is otherwise unchanged, so the same parsing code works.

Sets are periods. Set markets use period codes 1s through 5s, alongside game for the full match. A best-of-three women's match uses 1s to 3s; a best-of-five men's Grand Slam match runs to 5s. Tiebreaks are not modelled as their own period — they resolve inside the set they belong to.

Two different scoring stats. points carries the set score and decides the match, so it is what match-winner markets settle on. games carries the game count and is what totals and handicaps are priced on. Getting those two the wrong way round is the most common tennis integration mistake, because in most sports there is only one score stat.

Tennis Betting Markets

Available tennis markets include:

• Match winner (moneyline) on the set score
• Set winners — moneyline priced per set using 1s through 5s
• Total games over/under, for the match or for an individual set
• Games handicap (spread), the tennis equivalent of a point spread
• Total sets over/under
• Serving aces — match totals and per-player lines
• Break points won — match totals and per-player lines

All markets are available pre-match and live. Odds refresh sub-minute on the Pro plan, with Rookie and the free Amateur tier updating on a longer interval — see pricing for the frequency on each tier.

Tennis Player Markets

Because each player occupies a participant slot rather than a roster position, what would be a "player prop" in a team sport is addressed here through the home and away entity slots. Request serving_aces-home-game-ou-over for one player's ace total, or serving_aces-all-game-ou-over for the combined match total.

serving_aces and breakPoints are the two dedicated serving and return stats, and both are available at match level and per player. fantasyScore is also carried for DFS scoring formats.

The full list is in the stats reference, and markets & coverage shows which books support what.

Quick Start: Your First Tennis Odds API Call

Fetching tennis odds takes a single HTTP request:

https://api.sportsgameodds.com/v2/events?apiKey=YOUR_API_KEY&sportID=TENNIS&oddsAvailable=true&limit=10

This returns upcoming ATP and WTA matches with every available market. To narrow to a specific market, use oddIDs. This returns the total games line for each match:

https://api.sportsgameodds.com/v2/events?apiKey=YOUR_API_KEY&sportID=TENNIS&oddsAvailable=true&oddIDs=games-all-game-ou-over,games-all-game-ou-under

OddIDs follow the format {statID}-{statEntityID}-{periodID}-{betTypeID}-{sideID}. Swap game for 1s to get the first-set version of the same market, which is heavily traded in-play.

What a tennis response looks like

Every match returns an odds object keyed by oddID. Here's a trimmed total games market, with the bookmaker list cut to two books:

{
  "eventID": "...",
  "sportID": "TENNIS",
  "leagueID": "ATP",
  "odds": {
    "games-all-game-ou-over": {
      "oddID": "games-all-game-ou-over",
      "opposingOddID": "games-all-game-ou-under",
      "marketName": "Total Games Over/Under",
      "statID": "games",
      "statEntityID": "all",
      "periodID": "game",
      "betTypeID": "ou",
      "sideID": "over",
      "fairOdds": "-105",
      "fairOverUnder": "22.5",
      "bookOdds": "-110",
      "bookOverUnder": "22.5",
      "byBookmaker": {
        "bet365": { "odds": "-110", "overUnder": "22.5", "available": true },
        "pinnacle": { "odds": "-104", "overUnder": "23.5", "available": true }
      }
    }
  }
}

Note the statID is games, not points — this is a total on games won across the match, which is what tennis totals are priced on. A statEntityID of all means both players combined; swap it for home or away to get that player's own games total. Odds and lines both come back as strings, which preserves the leading + on plus-money prices.

Tennis Tours We Cover

• ATP — the men's professional tour, from tour-level events through the Grand Slams.
• WTA — the women's professional tour, across the full season calendar.

Both tours run near-continuously from January through November, which makes tennis one of the steadiest sources of daily events in the API — useful if you are building something that needs year-round liquidity rather than a seasonal spike.

Odds and results arrive in one unified response, so you can settle tennis markets without adding a second data source. Each response includes:

• Live, upcoming and completed matches
• Both players as event participants
• Match statistics, including aces and break points won
• Full odds coverage — match winners, games totals and handicaps, set markets and serving props
• Final results and settlement data

Use Cases for Tennis Odds Data

Odds Comparison Platforms — Show match odds and games lines from 85+ bookmakers side by side across both tours.

Arbitrage & +EV Tools — Tennis prices move sharply on withdrawals, injuries and surface changes, and books disagree more on early-round matches than on marquee ties.

Live & In-Play Products — Tennis is unusually well suited to in-play, because the scoring structure creates a natural pricing checkpoint at every game and set. Set-level period codes make those markets addressable directly.

Sports Analytics & Research — Serving and return stats support surface-adjusted modelling that headline match odds alone cannot.

Betting Automation — Monitor match and games lines across bookmakers and trigger actions when your target number appears.
