Weight of Money

The odds tell you the price. This tells you where the money went.

For every football market we track how much money is actually matched on each selection — not a bookmaker's price, the real split of the book. Volume, share, and how both moved since the last capture.

What you get

One request, the whole book

Every fixture returns its markets with the money split per selection. Share is the slice of that market's total; implied probability is what the attached price says it should be. The gap between them is the interesting part.

Six routes, that's the whole surface

Route	What it returns
/wom/api/coverage/	What the dataset holds right now. Free with any token.
/wom/api/events/	Fixtures with their latest money split. Filter by date, status, market.
/wom/api/events/<id>/	Every market for one fixture.
/wom/api/events/<id>/history/	Volume and share over time — the series behind a move.
/wom/api/movers/	Selections where money share and implied probability disagree most.
/wom/api/markets/	Market catalog and code format.

Event ids are BSD ids — the same ones the football API, the odds API and the WebSocket use. Join across all four without a mapping table.

Refresh rate

As fast as the numbers actually change

We poll at the cadence the source itself updates, so you are never reading a number that had already moved before we fetched it.

What	Refresh	Markets
In-play fixtures	every 15 seconds	Match odds, Over/Under 2.5, BTTS
Prematch fixtures	every 60 seconds	Popular set (1X2, O/U 1.5–3.5, BTTS)
Long-tail markets	hourly	Corners, cards, correct score, HT/FT, DNB

A row is stored only when volume or price actually moved, so captured_at is the real age of what you are reading — not the time we last ran. Polling, not push: for tick-level odds use the WebSocket.

Honest limits

What this is not

It is a description, not a prediction. A selection carrying 90% of the money is not a selection that wins 90% of the time. We publish the split and the divergence; we do not claim either one is an edge, and we have not back-tested it as a signal.

Coverage follows BSD. A fixture appears only when it resolves to a BSD event. Reserve sides, some women's leagues and smaller federations fall outside our football coverage and so fall outside this dataset. Check /wom/api/coverage/ before you build against it.

Capture cadence, not a live tick. Money is sampled on a schedule and a row is written only when it moved. Between captures the numbers are the last known ones — captured_at tells you exactly how old they are.
