Dam statistics
/v1/dams/{dam_id}/statsAvailable on Live Plus only
A Live key reaches the other 42 endpoints and
receives 403 upgrade_required here. Compare plans
How a dam's offspring run: strike rate, wins against the market, early pace and debut wins, whole and split by region, distance, trap, age and track.
Authenticate with your key in the X-API-Key header, or
?key= if your tool cannot set one —
see Authentication. Works with sandbox keys
inside the sandbox data window.
Parameters
| Name | In | Type | Required | Description |
|---|---|---|---|---|
dam_id |
path | integer | yes | The dam identifier. It is the dam_id on every row of Dams, and it stays the same from one weekly rebuild to the next. |

Common uses
First-time runners
A dog on debut has no form of its own. Its dam's debut_win_pct, with the number of debuts behind it, is as close as the record gets to that dog, and the sire's sits beside it.
Pedigree features for a model
Each split is a feature a model can use directly: the staying record for a dog stepping up in trip, the trap 1-2 record for a railer drawn inside. Every rate carries its counts, so thin evidence can be weighted down rather than trusted.
Breeding and sales research
actual_vs_expected separates offspring that win often from offspring that win more often than the market expects, which is the question behind a stud fee or a sale price. active_offspring and last_run show whether the record is current.
Notes
Rebuilt weekly from the archive; meta.coverage.built_at says when. Each split adds up to the overall figures, except that a run with no trap or no birth date on record is left out of by_trap or by_age. A dam not in the figures answers 404 not_found, with a message naming what is covered.
