betbetter

An R client for the Bet Better open sports model API — free, no API key, no registration.

For each upcoming fixture the API publishes a statistical model’s estimated probability that a selection occurs, and the decimal odds that probability implies. Fifteen competitions are covered across eight sports.

Installation

# install.packages("remotes")
remotes::install_github("edushinka/betbetter-r")

Usage

library(betbetter)

bb_leagues()
#>  [1] "afl" "mlb" "nba" "nfl" "nhl" "ncaaf" "ufc" "wnba" "wta" "epl"
#> [11] "laliga" "seriea" "bundesliga" "ligue1" "worldcup"

afl <- bb_picks("afl")
head(afl[, c("game", "selection", "model_probability", "fair_odds", "confidence")])

Argument	Purpose
`league`	League slug, e.g. `"afl"`, `"nba"`, `"epl"`
`feed`	`"picks"` (all), `"games"` (match markets), `"props"` (player markets)
`min_probability`	Drop selections estimated below this, 0–1
`limit`	Maximum rows returned

Returned columns

Column	Meaning
`game`	Fixture, `Away @ Home`
`start_time`	Scheduled start, UTC
`market`	Head to Head, Spread, Total Points, player markets…
`selection`	The team, player or outcome estimated
`line`	Handicap or total the selection is measured against
`model_probability`	Estimated chance the selection occurs, 0–1
`fair_odds`	Decimal odds implied by `model_probability`
`confidence`	`HIGH`, `LEAN` or `LONG-SHOT`
`verdict`	One-sentence plain-English summary

What this package cannot do

It returns no bookmaker prices. There is no bookmaker identity, market price or market-implied probability in the API, and none can be added — the upstream odds licence permits publishing derived work but not redistribution of the price feed. Everything here is the model’s own output.

Behaviour you should expect

A league outside its season returns a zero-row data frame. That is normal.
If the API is unreachable, bb_picks() emits a message and returns NULL rather than raising an error, so unattended scripts degrade gracefully.
Responses are cached upstream for 15 minutes.

Interpreting the estimates

These are model estimates, not statements of certainty. A selection estimated at 70% is expected to fail roughly three times in ten. Treat a losing run at that probability as ordinary variance rather than evidence of a broken model.
