A real response from /v1/owners/search?name=Racing, 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
owner_id	string	Opaque owner identifier, derived from the name because the source publishes none. Two owners sharing a name are one owner here.
name	string	Race title as published, sponsor and all.
runs	integer	Rides in the slice, priced or not.

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.
invalid_param	422	A date that is not YYYY-MM-DD, a by= dimension we do not have, or a cursor that did not come from us. The message names the parameter.
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.

What this is for

Owners by name, with runners, wins and the span of the record.

Owners are the one entity in this API with no source identifier at all. The source publishes a name and nothing else, so the identifier you get back is derived from that name. It is stable, it round-trips, and it is exactly as reliable as the name itself.

That has consequences worth stating plainly. A syndicate written two ways is two owners. "Mrs J Smith" and "Mrs Jane Smith" are two owners. A partnership that adds a member becomes a new owner. We do not merge any of those, because merging on a name similarity produces confident, wrong answers and there is no identifier to check them against.

Common uses

Finding a set of colours

Search the name as it appears in a racecard.

Checking before you rely on it

If the same owner appears twice under variant spellings, your analysis needs to combine them and only you can decide that they are the same.

Notes

Not every runner carries an owner. Where the source published none, the runner is absent from owner endpoints entirely rather than bucketed as unknown.
