Weight of Money API#

Odds tell you the price a book is willing to offer. This API tells you something different: how much money is actually sitting on each selection, and what share of the market that is.

Every football fixture we cover returns its markets broken down by selection, each with the money matched on it, its share of that market's total, the price attached to it, and the previous price. Captures are stored as a series, so you can also ask how the split got to where it is.

Base URL: https://sports.bzzoiro.com/wom/api/

In-play fixtures are refreshed every 15 seconds and prematch fixtures every 60 seconds — the cadence the numbers actually move at source. The long-tail markets (corners, cards, correct score) refresh hourly.

Football only today. Other sports will land on the same routes with a sport parameter; existing responses will not change shape when they do.

Access#

Authentication is the standard BSD token from your dashboard — the same one the football, odds and WebSocket products use. Send it on every request:

Authorization: Token YOUR_API_KEY

Access requires an active Weight of Money subscription — $20/month. Accounts holding the Founder badge (granted once to every account that existed before 2026-08-03) pay $10/month instead, and keep that price for as long as the subscription stays active. The badge cannot be earned by subscribing. This addon is separate from the Sports Addon and from the Odds API. Without a token you get 401; with a valid token but no subscription you get 402:

{"error": "active Weight of Money subscription required",
 "subscribe_url": "/wom/pricing/"}

GET /wom/api/coverage/ is the exception: any authenticated token may call it, so you can size the dataset before paying for it.

Subscribe at /wom/ or /addons/. Card subscriptions renew automatically; PayPal and crypto are one-time payments that stack months onto your expiry instead — pay a multiple of your monthly price to buy several at once.

Event identifiers#

Every row is keyed to a BSD event id — the same id used by /api/v2/events/{id}/, the odds API's bsd_id and the live WebSocket. There is no second identifier space and no mapping table to maintain.

A fixture appears in this API only once it resolves to a BSD event. See Coverage and limits.

Market codes#

Markets follow the same code format as the odds API: KIND[_LINE]_SELECTION_PERIOD.

Code	Meaning
1X2_HOME_FT	Home win, full time
1X2_DRAW_FT	Draw, full time
1X2_AWAY_FT	Away win, full time
1X2_HOME_1H	Home win, first half
OU_2.5_OVER_FT	Over 2.5 goals, full time
OU_1.5_UNDER_1H	Under 1.5 first-half goals
BTTS_YES_FT	Both teams to score
DNB_HOME_FT	Draw no bet, home
CORNERS_10.5_OVER_FT	Over 10.5 corners
CARDS_3.5_UNDER_FT	Under 3.5 cards
CS_2-1_FT	Correct score 2-1
HTFT_HOME-AWAY_FT	Home at half time, away at full time

GET /wom/api/markets/ returns the live catalog.

Field notes

Field	Meaning
volume	Money matched on this selection, in EUR
market_volume	Money matched across every selection of this market
share	volume / market_volume as a percentage
league_avg_volume	Typical market volume for this competition, or null when there is too little history. Use it to tell a busy market from a quiet one
price / previous_price	Decimal odds now and at the previous capture
implied_probability	100 / price. Includes the book's margin — it does not sum to 100 across a market
captured_at	When this row was sampled. Not a live tick; see below

GET /wom/api/events/{id}/history/#

The series behind a fixture. Ordered oldest first, ready to plot.

Param	Description
market	Restrict to one market code. Omit for every market on the fixture

{
  "event_id": 35898868,
  "series": {
    "1X2_AWAY_FT": [
      {"captured_at": "2026-08-04T09:00:00+00:00", "volume": 40120.0, "share": 88.1, "price": 1.2,  "market_volume": 45540.0, "is_live": false},

    ]
  }
}

A row exists only where the numbers changed, so gaps between points are periods when nothing moved, not missing data.

GET /wom/api/movers/#

Selections whose share of the money is furthest from what their price implies.

Param	Default	Description
min_volume	5000	Skip markets thinner than this
min_divergence	10	Minimum absolute divergence, in points
status	—	live, upcoming or finished
limit	25	Max 100

{
  "count": 1,
  "movers": [
    {
      "event": {"id": 35898868, "home_team": "Jeju SK", "away_team": "FC Bayern München"},
      "market": "1X2_AWAY_FT",
      "share": 94.73,
      "implied_probability": 90.09,
      "divergence": 4.64,
      "volume": 135838.0,
      "market_volume": 143388.0,
      "price": 1.11
    }
  ]
}

divergence is share − implied_probability, in points. Positive means more money is on the selection than its price implies.

Coverage and limits#

Read this before you build against the data.

It describes, it does not predict. A selection holding 90% of the money is not a selection that wins 90% of the time. We publish the split and the divergence as measurements. We make no claim that either is an edge and we have not back-tested them as a signal.

implied_probability carries the margin. It is a plain 100 / price, so across a full market it sums to more than 100. If you want a fair comparison against share, de-vig the prices yourself first.

Coverage follows BSD football coverage. A fixture is stored only when it resolves to a BSD event with confidence. Reserve teams, parts of the women's game and smaller federations sit outside our football coverage and therefore outside this dataset. GET /wom/api/coverage/ reports what is actually there.

Captures are periodic. In-play fixtures are sampled every 15 seconds and prematch fixtures every 60 seconds, which is as fast as the numbers change at source. The long tail of markets — corners, cards, correct score — is refreshed hourly. A row is written only when volume or price actually moved, so gaps in a series mean "nothing changed", not "data missing", and captured_at always tells you how old the state you are reading is.

This is a polling API, not a push stream. If you need to react within a second, poll /wom/api/events/?status=live on your own clock; for tick-level odds use the WebSocket.

Volumes are in EUR and reflect matched money on exchange-style markets, not total turnover across the whole betting market.
