A real response from /v1/trainers/tr_2QVAXT3, captured by calling the live API rather than written by hand.

Response fields

Each field is described once and rendered on every endpoint that returns it, so the wording cannot drift between pages.

Field	Type	What it is
trainer_id	string	Opaque trainer identifier.
name	string	Race title as published, sponsor and all.
runs	integer	Rides in the slice, priced or not.
win_pct	number	Wins over runs. The number everyone quotes and the one that tells you least.

Errors this endpoint returns

Code	Status	When
unauthorized	401	No key, or one we do not recognise. Check the header name and that the key has not been rotated from your account page.
not_found	404	The identifier is well formed but nothing has it. Distinct from invalid_id, which means the identifier itself is wrong.
invalid_id	422	The prefix does not match the kind of thing the path expects, or the identifier is malformed. A horse id passed where a race is wanted lands here rather than returning the wrong race.
rate_limited	429	Past your per-minute rate. Retry-After is set, and X-RateLimit-Remaining tells you where you stand on every successful response too.
server_error	500	Ours, not yours. Every response carries a request_id; quote it and we can find the exact request.

trainer_id

What this is for

One trainer: runners, wins, places, the date span of the record, and the horses sent out, most raced first.

These are counted from the races we hold rather than taken from a source field, so they describe what is in the archive rather than a career. The first and last dates tell you the span the figures cover, which matters for anyone who was training before 2017.

A strike rate is deliberately not the headline here. It is available, but on its own it mostly measures the quality of horse a yard attracts. /v1/trainers/{id}/stats is where the useful version lives.

Common uses

A trainer page

This plus the form endpoint covers it.

Finding a yard's string

The horses list is the roster as it appears in results, which is more current than any published string.
