💰 Pricing

Pay per event: $0.12 per 1,000 lines plus $0.005 per run start.

• A full NBA slate (913 lines in our test) ≈ $0.11 + $0.005 = $0.12.
• The whole board (about 8,700 lines in our test) ≈ $1.06.
• League listings are free apart from the run start.

Platform usage (compute and proxy traffic) is billed on top and is small: under one cent per run in our tests (about $0.001 for one league, $0.003 for the whole board).

❓ FAQ

Is it legal? It reads the public pick'em board any visitor sees, with no login. Use the data in line with Underdog's terms and the laws where you live.

Do I need an Underdog account or a proxy? No account. Underdog only serves visitors in the US and Canada, so the run uses US exits by default; you don't need to set anything.

How many lines can I get? Everything on the board. It changes all day: in our tests an October weekday morning had about 8,700 lines in 16 leagues, and leagues out of season have none. Use List available leagues to see the counts right now.

Why is a field empty? Some fields only exist for some lines: about half of the lines are higher-only, so the lower_* fields are empty; team fields stay empty for one-on-one sports such as tennis and UFC (the two players are in home_team_name and away_team_name); venue, weather and probable pitchers only appear when Underdog posts them.

Can I schedule it or use the API? Yes. Schedule runs (hourly on game days works well) and read the dataset over the API, or connect it to webhooks and automation tools.

Do filtered-out lines cost money? No. Only saved lines are charged.

⚠️ Limits

• Lines change by the minute; each run is a snapshot of the board at scraped_at.
• Only the public pre-game pick'em board. Alternate lines (has_alternates) are flagged but not expanded, and live in-game lines and account data such as your own entries are not covered.
• Historical lines and results are not available; store your own snapshots to build a history.
