Bet Better API Review 2026

Bet Better runs a sports betting model and publishes its output as a free API. Each entry is the model's own view of one selection: the chance it lands, a fair-odds figure, a confidence label and a one-sentence verdict. On top of the picks feeds sit predicted final scores and fantasy projections, all read-only and all keyless.

The important part is what the feed leaves out. Bet Better says the feed carries no sportsbook names and no market prices. It licenses its odds from a third party and is only allowed to publish work derived from them, so the docs say plainly that bookmaker prices are not coming. What you get is a probability layer. The market price comes from somewhere else.

The free feed is licensed CC BY 4.0, which permits commercial use as long as you credit Bet Better. The company also sells paid feeds to businesses under the Bet Better Data name, covered further down.

The picks feeds cover the NFL, NBA, MLB, NHL and WNBA, college football (NCAAF) and college basketball (NCAAB), the AFL and NRL, UFC, cricket, ATP and WTA tennis, and soccer: the Premier League, La Liga, Serie A, the Bundesliga, Ligue 1, MLS and the World Cup. Each league has three feed shapes:

• best-bets returns game lines only: moneyline, spread and total.
• prop-bets returns player-prop selections only.
• picks returns both, ranked.

Two more feeds come in CSV as well as JSON. Predicted scores (/predicted-scores/{sport}) give one row per upcoming game with each side's projected score, the home margin, the total and the home win probability, across eleven sports. Fantasy projections (/fantasy/{sport}) rank players by projected points under PPR, half-PPR, standard, DraftKings and FanDuel scoring for the NFL, and the relevant formats for the NBA, NHL, WNBA and AFL, with the projected stat line alongside.

Coverage follows the calendar. Fixtures that have started drop out, so a league's feed is empty in its off-season, and the docs flag that as expected behavior.

The API is the website. Take any picks page and add ?format=json:

curl "https://betbetter.world/nfl/picks?format=json"

Each league's free picks carry the fixture, the UTC start time, the market, the selection, the line where there is one, the model's probability as a percentage, a fairOdds figure in decimal format, a confidence label (HIGH, LEAN or LONG-SHOT) and a dated verdict sentence. Every other pick is a members-only row with the game, the start time and the market, marked locked (checked November 2026). The envelope repeats the licence, the attribution string and an updatedUtc timestamp, so a cached copy always says how old it is.

The probability is the field to build on. Turn it into a break-even price (100 divided by the percentage), set that next to a sportsbook's price from an odds API, and the gap is the model's claimed edge. That comparison is the job Bet Better expects you to do with it. The feed also ships that break-even price as fairOdds, in decimal format.

The practical details are tidy. There is an OpenAPI 3.0 spec, CORS is on, and a data error comes back as a valid document with an error field instead of a 500. Predicted-score columns are fixed and will not change without notice, which matters if you poll them into a tracker.

A model feed is only worth the model, and Bet Better publishes its track record. The /scorecard feed lists only the sports and markets where the model is ahead over the last 120 days, with picks, wins and ROI, and the OpenAPI file marks it as not maintained. The full settled record, losers counted the same as winners, sits at /results?format=json in 7-, 30- and 90-day windows (checked November 2026).

That is unusual for a picks site, and it is the right thing to check before you build on the numbers. Some sport and market pairs hold up better than others, and the scorecard shows which ones.

Bet Better Data is the paid side, and it works differently from the free feed. It needs a key, sent as &key= on the address or as a Bearer header, and every product sits behind one address, /data/feed.aspx, with a league code and a file name. Four products are sold on their own:

• Predictions feed. The full weekly board for 22 leagues: the model's spread, total, win chance and no-margin prices for every game, plus player props, alternate lines, period markets and fantasy points. Each row carries the market's line at publish time as a reference. Every version of a week is kept, so you can fetch exactly what the board said at any point. Files come as CSV, JSON or XLSX.
• Line Moves. Calls on which way a line will move before the start, UP or DOWN, with a strength label and the historical hit rate for that kind of call. Six sports.
• Bets feed. Bets from the model's profitable bet types, each with the lowest price worth taking and a stake in units. Bet Better limits the number of buyers so the bets do not move the market.
• Storylines. Checked facts on teams, players and match-ups, plus a writing endpoint that turns them into posts, threads or scripts. Every number in a piece is checked against the facts before it comes back.

Delivery is where the paid side goes past plain REST. Save a webhook address and Bet Better POSTs each new board version, Line Moves batch or bet batch to your server, signed with HMAC-SHA256. Google Sheets and Excel can also pull the CSV files straight from the address. Feeds allow 60 requests a minute per key, or 240 on every-league plans.

The open API is free. There is no key, no signup and no hard rate limit. Responses are cached for 15 minutes (fantasy projections for an hour), the model refreshes several times a day, and the docs ask you to cache on your side instead of polling in a tight loop. A status and changelog page records when each feed last got new data.

The licence is CC BY 4.0. You may use, transform and redistribute the free data, commercially included, with credit to Bet Better. A link back to the site covers it.

The paid feeds have published prices, in US dollars a month:

• Predictions feed: $1,500 for the first league, $750 for each extra league, and $7,500 for every league. Soccer's ten leagues count as three. A four-week pilot costs $299 for up to three leagues, and the $299 comes off the first month.
• Line Moves: $2,500 for the first sport, $1,500 for each extra sport, and $8,500 for all six. A sport is not billed until its first live call.
• Bets feed: $12,500, one price.
• Storylines: $99 (Creator), $399 (Pro, with the facts API) or $1,490 (Publisher).
• Everything: $24,900 for all four products.

There is no contract. You pay monthly, or yearly at 12 months for the price of 10, and cancel from your account. To show the paid numbers inside your own app, you need a commercial licence, from $9,500 a month. The paid side has no free trial, but each league has a free sample file.

• Sportsbook prices. By design and by licence. Pair the feed with an odds provider from the directory to get the market side.
• Live and in-play. Started fixtures leave the feed, so this is a pregame tool. For in-play numbers, look at the live odds API category.
• Scores and stats. The API projects scores and stat lines; it does not report actual results, box scores or standings. A sports data API fills that gap.
• Push on the free feed. The free API is plain REST with a 15-minute cache, which suits a feed that refreshes a few times a day. Webhooks come only with the paid feeds.
• Esports. Not covered.

The free Open Model API has no key. Add ?format=json to a picks page and the feed comes back, with no sign-up (checked November 2026). The one ask is a credit: link to Bet Better wherever you show the data. The API page lists every league path.

The paid Bet Better Data feeds do use a key. You pay by card on the Data site, and the key arrives by email the minute the payment clears. It also sits on your account page, where you can swap it for a new one. Keys start with bbd_live_. Send one as &key= on the address or in an Authorization: Bearer header, and the one key covers every product on your account. Each league also has a free sample file that needs no key.

This sample reads the free NFL picks feed, from the docs, checked November 2026. The API is the website with ?format=json added, so the path is /nfl/picks. Free picks come back whole. Every other pick is a locked row that holds only the game, start time and market, so the script skips rows where locked is true.

import requests

resp = requests.get(
    "https://betbetter.world/nfl/picks",
    params={"format": "json"},
    timeout=10,
)
resp.raise_for_status()
feed = resp.json()

print("updated:", feed["updatedUtc"])
for pick in feed["picks"]:
    if not pick["locked"]:
        print(pick["game"], pick["market"], pick["selection"], pick["line"])
        print("   chance", pick["modelProbabilityPct"], "fair odds", pick["fairOdds"], pick["confidence"])

An open pick carries game, market, selection, line, modelProbabilityPct, fairOdds and confidence. The fair odds are 100 divided by the chance, a break-even price in decimal format, and never a bookmaker price. In a league's off-season the list is empty.

The free feed has no hard limit, so only the paid side meters you (checked November 2026). Over a limit, a call gets a 429 with a Retry-After header. Errors arrive as JSON, such as {"ok":false,"error":"..."}, and a 403 means that your plan doesn't cover that league. Storylines allows 20 requests a minute on Creator, 30 on Pro and 120 on Publisher.

The free API has an OpenAPI 3.0 spec, and the paid feeds have their own docs. A status and changelog page shows when each free feed last got data. Python users can install betbetter, the client that Bet Better lists in its own apis.json. An MCP server runs at betbetter.world/mcp, with free tools at /mcp/free (30 calls a minute); see sports MCP servers. Help for the paid feeds is data@betbetter.world.

• Odds comparison and value-finder tools that already carry market prices and want an independent probability to rank bets against.
• Prediction trackers and aggregators. The predicted-scores CSV is built for them, with fixed columns and an invitation to poll.
• Fantasy and DFS side projects that need free projections in up to five scoring formats without scraping.
• Content sites and newsletters that want to quote a model's number with a clean licence and a ready-made attribution line.
• Sportsbooks, trading desks and media teams with a budget. The paid feeds add the full board, line-move calls and checked stats for writers, with webhooks to push them into your own system.
• Students and modelers who want to benchmark their own model against a published one with a public record.

For the AFL, Bet Better also publishes an open dataset of 206,722 player-match records from 2000 to 2023 under the same licence. It is a good companion to the sources on our free sports datasets page.

Most free sports APIs hand you raw data and leave the modeling to you. This one hands you the model's answer: a probability, a fair-odds figure and a confidence label for each league's free picks across twenty leagues, with no key and a licence that allows commercial use. It is honest about its limits, from the missing bookmaker prices to the public results feed, and that honesty makes it easy to trust as one input among several.

Use it as a second opinion next to a price feed, not as a price feed. Start with ?format=json on the league you care about, check the scorecard for that sport, and read the docs for the full list of paths.

The paid feeds are priced for businesses: $1,500 a month buys one league of the full board. The $299 pilot is the cheaper way to test whether the extra numbers are worth it for your product.
