### Worked example: pulling moneyline odds

Source: https://oddsapir.sportsdataverse.org/articles/oddsapiR.html

Minimal workflow: check quota, pull NBA moneyline odds, inspect, and find best lines.

```r
library(oddsapiR)
library(dplyr)

# 1. Verify a key exists and check starting budget
check_toa_key()
toa_requests()
# requests_remaining = 500, requests_used = 0

# 2. Pull moneyline (h2h) odds for the NBA from US books
nba_h2h <- toa_sports_odds(
  sport_key   = "basketball_nba",
  regions     = "us",
  markets     = "h2h",
  odds_format = "decimal",
  date_format = "iso"
)

# 3. Inspect: one row per (event x bookmaker x outcome)
glimpse(nba_h2h)
# Rows: ~120
# Columns: id, sport_key, sport_title, commence_time, home_team, away_team,
#           bookmaker_key, bookmaker, bookmaker_last_update,
#           market_key, market_last_update, outcomes_name, outcomes_price

# 4. Find the best moneyline price for each team across all books
best_lines <- nba_h2h %>%
  group_by(home_team, away_team, outcomes_name) %>%
  slice_max(outcomes_price, n = 1) %>%
  select(home_team, away_team, outcomes_name, bookmaker, outcomes_price)

best_lines
```

--------------------------------

### Check API key and budget with check_toa_key() and toa_requests()

Source: https://oddsapir.sportsdataverse.org/articles/building-an-odds-pipeline.html

```r
check_toa_key()
```

```r
budget_before <- toa_requests()
budget_before
# # A tibble: 1 x 2
#   requests_remaining requests_used
#                <int>         <int>
#                  480            20
```

### toa_function wrapper example using toa_api_call and tryCatch

Source: https://oddsapir.sportsdataverse.org/CLAUDE.html

Shows the standard structure for an endpoint wrapper: builds a base URL and query list, initializes the return variable before tryCatch, calls toa_api_call, and returns the result unconditionally. Uses cli alerts for errors and warnings.

```r
toa_function <- function(sport_key, regions = 'us', markets = 'h2h', date_format = 'iso'){
  base_url <- glue::glue('https://api.the-odds-api.com/v4/sports/{sport_key}/odds')
  query_params <- list(
    apiKey      = as.character(toa_key()),
    regions     = regions,
    markets     = markets,
    dateFormat  = date_format
  )

  odds <- data.frame()   # initialize return var BEFORE tryCatch (see below)

  tryCatch(
    expr = {
      odds <- toa_api_call(base_url, query = query_params) %>%
        # ... parse ...
        make_toa_data("Sports Odds data from the-odds-api.com", Sys.time())
    },
    error = function(e) {
      cli::cli_alert_danger("{Sys.time()}: Invalid arguments or no data available for {sport_key}!")
      cli::cli_alert_danger("Error:\n{e}")
    },
    warning = function(w) {
      cli::cli_alert_warning("{Sys.time()}: Warning:\n{w}")
    },
    finally = {}
  )
  return(odds)
}
```

--------------------------------

### toa_event_markets() example with error output

Source: https://oddsapir.sportsdataverse.org/reference/toa_event_markets.html

Example call to toa_event_markets() with a basketball_nba sport_key and a specific event_id. The output shows an error when no markets data is available: the function returns a 0x0 data frame and emits an error about renaming a non-existent column.

```r
# \donttest{
   try(toa_event_markets(sport_key = 'basketball_nba',
                         event_id = '48db9c3293a52baab881d95d38f37a98',
                         regions = 'us'))
#> ✖ 2026-10-09 05:38:11.033617: Invalid arguments or no markets data available for event 48db9c3293a52baab881d95d38f37a98!
#> ✖ Error:
#> Error in `dplyr::rename()`:
#> ! Can't rename columns that don't exist.
#> ✖ Column `key` doesn't exist.
#> data frame with 0 columns and 0 rows
# }

```r
all_sports <- toa_sports(all_sports = TRUE)

# Sports currently in season
in_season <- all_sports %>%
  filter(active) %>%
  select(key, group, title)

in_season
# key                      group              title

### List upcoming NBA events with toa_sports_events()

Source: https://oddsapir.sportsdataverse.org/articles/building-an-odds-pipeline.html

Lists in-play and pre-match events for the NBA without odds using `toa_sports_events()`. The `id` column in the result is the `event_id` used by `toa_event_odds()` and `toa_event_markets()`. This example sets a 24-hour window from the current UTC time.

```r
# Events for the next 24 hours
now      <- format(Sys.time(), "%Y-%m-%dT%H:%M:%SZ", tz = "UTC")
tomorrow <- format(Sys.time() + 86400, "%Y-%m-%dT%H:%M:%SZ", tz = "UTC")

nba_events <- toa_sports_events(
  sport_key          = "basketball_nba",

### devtools workflow commands for oddsapiR development

Source: https://oddsapir.sportsdataverse.org/CONTRIBUTING.html

Run these devtools commands in sequence during development: load_all() to load the package, document() to regenerate man/ and NAMESPACE after roxygen changes, test() to run the test suite (requires ODDS_API_KEY), build_readme() to re-render README.md from README.Rmd, and check() for a full R CMD check before opening a PR.

```R
devtools::load_all()      # load the package

### Usage of toa_sports_odds_history()

Source: https://oddsapir.sportsdataverse.org/reference/toa_sports_odds_history.html

Shows the function signature with all arguments and defaults. Use this to call the function with a sport_key and date to get historical odds.

```r
toa_sports_odds_history(
  sport_key,
  date,
  regions = "us",
  markets = "spreads",
  odds_format = "decimal",
  date_format = "iso",
  event_ids = NULL,
  bookmakers = NULL
)
```

### Fetch detailed props for a single game with toa_event_markets() and toa_event_odds()

Source: https://oddsapir.sportsdataverse.org/articles/building-an-odds-pipeline.html

First, discover available markets for a game using toa_event_markets() (costs 1 credit). Then fetch odds for a specific market (player_points) with toa_event_odds(), costing 1 market x 1 region = 1 credit. The output shows the distinct bookmaker-market combinations and the first 10 player-points props with decimal odds.

```r
game_id <- "48db9c3293a52baab881d95d38f37a98"  # from toa_sports_events()

# Discover available markets for this game (1 credit)
available_markets <- toa_event_markets(
  sport_key = "basketball_nba",
  event_id  = game_id,
  regions   = "us"
)

available_markets %>%
  distinct(bookmaker, market_key) %>%
  arrange(bookmaker, market_key)
# bookmaker    market_key
# DraftKings   h2h
# DraftKings   player_points
# DraftKings   player_rebounds
# DraftKings   spreads
# DraftKings   totals
# FanDuel      h2h
# FanDuel      player_points
# ...
```

```r
# Fetch player-points props (cost: 1 market x 1 region = 1 credit)
player_pts <- toa_event_odds(
  sport_key   = "basketball_nba",
  event_id    = game_id,
  regions     = "us",
  markets     = "player_points",
  odds_format = "decimal",
  date_format = "iso"
)

player_pts %>%
  select(bookmaker, outcomes_name, outcomes_description, outcomes_price, outcomes_point) %>%
  head(10)
# bookmaker    outcomes_name  outcomes_description  outcomes_price  outcomes_point
# DraftKings   Over           LeBron James          1.91            25.5
# DraftKings   Under          LeBron James          1.91            25.5
# FanDuel      Over           LeBron James          1.87            25.5
# FanDuel      Under          LeBron James          1.95            25.5

### Build 6-snapshot series with toa_event_odds_history

Source: https://oddsapir.sportsdataverse.org/articles/building-an-odds-pipeline.html

Builds a 6-snapshot series for a specific event using toa_event_odds_history, pausing 0.5 seconds between calls to respect rate limits. Stops early if a snapshot returns zero rows. The output shows the resulting line movement for DraftKings spreads, with timestamps and point changes.

```R
event_id   <- "93af4b300a4c0dded909234ea32e9abd"
start_date <- "2024-01-13T12:00:00Z"
n_snapshots <- 6

snapshots <- list()
current_date <- start_date

for (i in seq_len(n_snapshots)) {
  snap <- toa_event_odds_history(
    sport_key   = "basketball_nba",
    event_id    = event_id,
    date        = current_date,
    regions     = "us",
    markets     = "spreads",
    odds_format = "decimal",
    date_format = "iso"
  )

  if (nrow(snap) == 0) break

  snapshots[[i]] <- snap
  current_date   <- snap$next_timestamp[[1]]

  # Be kind to the API rate limit
  Sys.sleep(0.5)
}

line_movement <- bind_rows(snapshots) %>%
  filter(market_key == "spreads", bookmaker_key == "draftkings") %>%
  select(timestamp, home_team, away_team, outcomes_name,
         outcomes_price, outcomes_point)

line_movement
```

```text
# timestamp                 home_team           away_team       outcomes_name       price  point
# 2024-01-13T12:00:00Z      Los Angeles Lakers  Boston Celtics  Los Angeles Lakers  1.91   -4.5

### Store snapshots to SQLite with DBI and RSQLite

Source: https://oddsapir.sportsdataverse.org/articles/building-an-odds-pipeline.html

Sets up a SQLite archive with DBI and RSQLite, creating an odds_snapshots table keyed by pulled_at. The pull_and_store function fetches odds via toa_sports_odds, appends rows, and reports success; it returns early if no rows are returned. Close the connection with dbDisconnect when done.

```R
# --- one-time setup ---
con <- dbConnect(RSQLite::SQLite(), "odds_archive.sqlite")

# Create the table if it doesn't exist yet
dbExecute(con, "
  CREATE TABLE IF NOT EXISTS odds_snapshots (
    pulled_at         TEXT,
    snapshot_ts       TEXT,
    event_id          TEXT,
    sport_key         TEXT,
    sport_title       TEXT,
    commence_time     TEXT,
    home_team         TEXT,
    away_team         TEXT,
    bookmaker_key     TEXT,
    bookmaker         TEXT,
    market_key        TEXT,
    outcomes_name     TEXT,
    outcomes_price    REAL,
    outcomes_point    REAL
  )
")

# --- called on each scheduled pull ---
pull_and_store <- function(sport_key, regions = "us", markets = "h2h,spreads") {
  pulled_at <- format(Sys.time(), "%Y-%m-%dT%H:%M:%SZ", tz = "UTC")

  raw <- toa_sports_odds(
    sport_key   = sport_key,
    regions     = regions,
    markets     = markets,
    odds_format = "decimal",
    date_format = "iso"
  )

  if (nrow(raw) == 0) return(invisible(NULL))

  to_store <- raw %>%
    mutate(pulled_at = pulled_at) %>%
    select(
      pulled_at, snapshot_ts = bookmaker_last_update,
      event_id = id, sport_key, sport_title,
      commence_time, home_team, away_team,
      bookmaker_key, bookmaker, market_key,
      outcomes_name, outcomes_price,
      # outcomes_point may be NA for h2h
      outcomes_point = dplyr::any_of("outcomes_point")
    )

  dbAppendTable(con, "odds_snapshots", to_store)
  cli::cli_alert_success("Stored {nrow(to_store)} rows at {pulled_at}.")
