Can I test against it out of season?

Yes. Generated harness racing has no season. Races run a few minutes apart on every day of the year, so a test you write in July behaves the same in January.

Does the schedule stop when there is no real trotting?

No. The events do not come from a track calendar. They are generated on a steady cycle, so the schedule looks the same at 03:00 on a public holiday as on a weekday afternoon.

Is this real harness racing data?

No. Every event, runner and result is computer-generated. The names are invented and the odds are not a real market. Nothing in the feed refers to a real horse, driver or track.

What harness racing data does the API return?

Scheduled and finished events, runners with draw numbers and form, win and place odds, and results with win, place, forecast and tricast settlement. Every endpoint returns JSON over REST.

Is there a free plan?

Yes. The free plan is $0 and includes 500 requests a day. You do not need a credit card. Paid plans start at $59 a month for 15,000 requests a day.

How do I authenticate?

Sign in at dashboard.sportlogic.io with Google and copy your key. Send it in the X-API-Key header on every request.

Harness racing

Virtual harness racing API

Virtual harness racing data in JSON. The races are computer-generated, so there is no trotting season to wait for and no meeting is called off. The API returns events, runners with draw numbers and form, win and place odds, and settled results.

How generated racing differs from a real feed

Real trotting runs to a season and to each track's own calendar. This feed runs to neither. A race is scheduled every few minutes, day and night, every day of the year.

Load test against live data
The schedule never empties, so you can point a load test at real responses at any hour. You do not have to record a set of canned responses first, or wait for a race day.
A fixed cadence to size your cache
Events arrive on a steady cycle rather than in bursts around real meetings. One cache window and one poll interval hold at 03:00 on a public holiday the same as on a Saturday afternoon.
No canceled events to handle
You never write a branch for an abandoned meeting, a postponed start or an empty day in the calendar. An event that is scheduled runs, and it settles.
Settlement arrives with the result
The finishing order and the win, place, forecast and tricast settlement come back in one response. A settled result does not change, so you can cache it and never reconcile it.

Game types

Harness Racing

Harness racing

This is one of the 8 racing game types the API serves. One integration covers all of them. The response shape does not change between game types.

Quick start

Authenticate with the X-API-Key header. List game types with /game-types, then filter events with the game_type_id and status parameters.

curl

curl -H "X-API-Key: YOUR_KEY" \
  "https://virtuals-api.sportlogic.io/api/v1/events?status=scheduled"

Sample event response

GET /api/v1/events/{id} returns the event and every runner with draw number, win and place odds, and form. Odds are decimal.

The event also carries id and game_type_id. The API assigns both, so read them from /game-types and /events rather than copying numbers off this page.

Results and settlement

When the event finishes, GET /api/v1/events/{id}/results returns the finishing order plus win, place, forecast and tricast settlement. You can grade bets straight from this response.

Cache responses while you build

The free plan includes 500 requests a day. That covers a full day of building if you cache. Store each response by event id and read from the cache instead of calling the API again for the same data. Fetch the schedule on a timer, not on every render. The cadence is the same at every hour, so one interval works all day. A settled result never changes, so you can cache results forever.

JavaScript

const cache = new Map();

async function getEvent(id) {
  if (!cache.has(id)) {
    const res = await fetch(`${BASE}/events/${id}`, { headers });
    cache.set(id, await res.json());
  }
  return cache.get(id);
}
