Honest comparison · updated 2026
The Rundown alternative: odds plus the whole game
The Rundown is tuned for betting, odds, line movement, and scores. Big Balls Sports Data gives you all of that plus lineups, stats, events, and players under one schema, returned in a single call. If deep line-movement history is your whole product, theirs is purpose-built for it. If you are building a live betting or fantasy experience, the math changes.
One Big Balls call returns the full matchup. The Rundown bills returned data rows as data points and separates betting and stats surfaces, so the exact usage depends on the books, markets, and rows you request.
What you would pay at your scale vs The Rundown
10,000 upstream requests/day after your own caching. For per-sport products, the model distributes that traffic evenly across selected sports.

Comparison basis
The Rundown bills returned rows as data points. This estimate uses one data point per projected upstream request, which is a best-case lower bound. Actual odds snapshots bill each returned price row plus event and score rows.
Raw The Rundown pricing covers the data subscription only. The assembly layer, intelligence features, and cross-sport unification are engineering time you build and maintain.
The Rundown price = raw data subscription only. Assembly layer, intelligence features, and cross-sport unification are not included at any tier. Pricing verified 2026-10-04. Single subscription covers all sports. Plans bind on BOTH a per-second rate ceiling AND a monthly data-points quota. Real-time (no delay) and WebSocket delivery land on the Ultra tier and above.

Live betting second screen
Show live odds next to live scores, lineups, and injuries on one screen, fed by a single WebSocket subscription.

Combine odds with NBA play-by-play (1946 to 2023) and NFL EPA to test a handicapping model end to end.
Fantasy lineup optimizer
Confirmed lineups, injuries, and the odds for each matchup arrive in the same envelope, no cross-referencing two APIs.
World Cup 2026 hub
Group standings, Elo win probabilities, and live odds for every match.
Against-the-spread dashboard
Team ATS records with home/away and favorite/underdog splits, returned ready to render, no aggregation code.
One call that closes the gap
A live request against the gateway that returns something you would have to stitch together, or could not get at all, on The Rundown.

Burst limits, on every plan
Per-minute burst is what decides whether a page that fans out into several calls renders or throttles. Here is the whole ladder, daily cap included, so you can compare it against what The Rundown publishes — we state ours and leave theirs to their own page, which is the only copy either of us can keep current.
| Plan | Per minute | Per day |
|---|---|---|
| Free | 100 | 250 |
| Solo | 300 | 10,000 |
| Trio | 500 | 25,000 |

Requests are counted one for one — no credit weighting, no markets-times-regions arithmetic — so the number in this table is the number of calls you can make. How rate limiting works →
Start on the free tier
100 requests per minute and 250 per day, free — the highest per-minute burst of any free sports API we checked. Burst is what matters when something asks several questions in a row and waits on each answer.
- Every sport and league we cover — the paid tiers add history depth and premium fields, not more leagues.
- Calls are counted one for one — no credit weighting, no markets-times-regions arithmetic.
- Link GitHub and the daily cap goes to 500.
- No credit card.

Frequently asked
- Is Big Balls Sports Data a drop-in replacement for The Rundown?
- If you consume odds and scores, migration is straightforward. Our /v1/matches/:id/odds endpoint covers the major markets and our matchup responses bundle the rest. If your product depends on detailed opening and closing line history, you would keep The Rundown alongside us during a transition.
- How does the odds depth compare?
- We cover the major US and EU bookmakers with pre-match and in-play markets (moneyline, spread, total, run-line, puck-line). The Rundown carries deeper historical line-movement and opening/closing line data that we do not currently expose.
- Do you have closing line value (CLV) data?
- Closing lines are not a first-class field in our envelope yet. If CLV analysis is core to your product, The Rundown's line-history endpoints are more direct.
- What do I get that The Rundown does not offer?
- A product-ready game response with lineups and injuries next to the odds, NFL play-by-play with EPA, NBA history back to 1946, Elo win probabilities, and against-the-spread splits under one schema. The Rundown also offers real-time WebSocket delivery on Ultra and higher, so streaming itself is not a unique advantage.
