The Odds API vs. MoneyLine Sports API
The broadest raw odds feed vs. a US-focused API with props, hit rates and betting edges built in. What each does better, and how to switch.

The Odds API is where a lot of sports betting projects start: clean docs, a free tier, and odds from 113 bookmakers across the US, UK, Europe and Australia. If you need raw odds for many sports and many countries, it is hard to beat.
Teams usually go looking for an alternative when their roadmap moves past raw lines: player props for every game in one call, hit rates, +EV and arbitrage signals, or predictable costs when they pull lots of markets. That is where MoneyLine Sports API is built to help.
This page compares the two honestly, including where The Odds API wins, and then walks through a migration: which endpoint replaces which, how the fields map, and working code.

Round by round
Bookmaker and sports coverage
The Odds API
113 bookmakers across 11 regions, including Pinnacle and Betfair Exchange, and a long list of sports. If your users are outside the US, or you need tennis, golf or cricket, this is the deciding factor.
MoneyLine API
Focused on US betting: 19 US sportsbooks, the major DFS apps and US exchanges and prediction markets, across 9 leagues. Deep, but not wide.
For international books and non-US sports, The Odds API covers far more.
Round goes to The Odds APIPlayer props
The Odds API
Props come from the event odds endpoint, one game per call, for selected sports and books. A full NFL Sunday means one request per game, and each market adds to the credit cost.
MoneyLine API
One request returns props for every upcoming game in a league, with every book's price on each line and the best price flagged. Hit rates for each player and line come from a separate endpoint.
Fewer calls and hit rates built in make prop products much faster to build.
✓ MoneyLine takes the roundBetting edges: +EV, value and arbitrage
The Odds API
Raw odds only. Edge math is left to you.
MoneyLine API
Dedicated endpoints for +EV, value and arbitrage, with DFS excluded from arbitrage and exchange prices sanity-checked, plus fair odds and best price on every event.
If your product recommends bets, this is weeks of work you skip.
✓ MoneyLine takes the roundCost when you pull many markets
The Odds API
Cost scales with markets × regions per call, so pulling moneyline, spread and total from two regions costs 6 credits per request. It is transparent, but it adds up.
MoneyLine API
A bulk odds call costs 6 credits for every game line from every US book. Starter buys about 25,000 of those pulls a month for $29; The Odds API's $30 plan buys about 1,666 all-US pulls.
Multi-market, all-book pulls are cheaper and easier to forecast.
✓ MoneyLine takes the roundHistorical data
The Odds API
Odds history back to 2020 and prop history back to May 2023 on paid plans.
MoneyLine API
Line-movement history starts in September 2026, and each game's history is deleted about two days after kickoff. Fine for recent movement, not for backtests.
For backtesting over several seasons, The Odds API has years more data.

Choose The Odds API for international bookmakers, non-US sports or multi-season backtesting. Choose MoneyLine Sports API if you are building a US betting product that needs player props across every game, hit rates, or +EV and arbitrage signals without building them yourself.
How to switch from The Odds API
- Get a free MoneyLine key at moneylineapp.com/signup.
- Point requests at https://mlapi.bet and send the key in the x-api-key header instead of the apiKey query parameter, or use the official SDK.
- Swap sport keys for league IDs using the table below.
- Rename fields using the field map. Prices are always American odds, so drop oddsFormat.
- Replace per-event prop loops with one /v1/player-props call per league.
- If you compute +EV or arbitrage yourself, compare your results with /v1/edge/ev and /v1/edge/arbitrage, then remove the code you no longer need.

Before and after
Before: The Odds API
const url = 'https://api.the-odds-api.com/v4/sports/americanfootball_nfl/odds'
+ '?apiKey=' + process.env.ODDS_API_KEY
+ '®ions=us&markets=h2h,spreads&oddsFormat=american'
const games = await (await fetch(url)).json()
for (const g of games) {
console.log(g.home_team, g.bookmakers.map((b) => b.key))
}After: MoneyLine Sports API (npm install moneyline-sports-api)
import { MoneyLine } from 'moneyline-sports-api'
const ml = new MoneyLine({ apiKey: process.env.MONEYLINE_API_KEY })
const games = await ml.odds({ league: 'nfl' })
for (const g of games) {
console.log(g.homeTeamName, g.bookmakers.map((b) => b.bookmakerId))
}What The Odds API has that MoneyLine doesn't
- Bookmakers outside the US, including Pinnacle and Betfair Exchange.
- Sports beyond our 9 leagues, such as tennis, golf, cricket and MMA.
- Historical odds for past games.
- Decimal odds output, deep links to bet slips and bet limits.
Why MoneyLine wins for builders
MoneyLine uses the same bookmaker keys as The Odds API (draftkings, fanduel, betmgm and so on) and the same outcome shape of name, price and point, so most code ports with a few renames. The table below covers each one.
What you gain is the layer most teams end up building on top of a raw odds feed: league-wide props in one call, hit rates, no-vig fair odds, best available price, and +EV, value and arbitrage endpoints. Official TypeScript and Python SDKs are available as moneyline-sports-api on npm and PyPI.
FAQ
+−Is MoneyLine Sports API a drop-in replacement for The Odds API?
For US leagues, close to it. Bookmaker keys are the same and outcomes use the same name, price and point fields, so most code needs renames rather than a rewrite. If you rely on international books, non-US sports or long odds history, The Odds API covers more.
+−Does The Odds API offer +EV or arbitrage endpoints?
No. It provides raw odds and leaves edge math to you. MoneyLine offers +EV, value and arbitrage endpoints, with DFS prices excluded from arbitrage and exchange prices checked against sportsbook consensus.
+−Does either API include Pinnacle or Betfair Exchange?
The Odds API does: Pinnacle in its EU region and Betfair Exchange in its UK, EU and AU regions. MoneyLine focuses on US books and does not include them. Live counts of what MoneyLine covers are at moneylineapp.com/coverage.
+−How long does migrating take?
For a US-focused prototype, usually an afternoon: change the base URL and auth header, map sport keys to league IDs, and rename a handful of fields using the tables above.
