Horse Racing Data API

REST access to over a decade of horse racing data across the UK, Ireland, Australia and the US: Betfair starting prices, forward racecards with live prices, and per-horse career profiles.

All endpoints are read-only GET requests returning JSON, served from https://horses.sportsedgepro.co.uk. A machine-readable OpenAPI 3.0 spec is available for client generation.

Authentication

Every endpoint except the discovery document requires an API key, sent as a bearer token. The API has its own account system, separate from the SportsEdgePro dashboard login — create a developer account, subscribe to a plan, and manage keys from your developer account page.

# Recommended: Authorization header
curl -H "Authorization: Bearer sep_live_YOUR_KEY" \
  "https://horses.sportsedgepro.co.uk/api/v1/prices?country=UK&limit=5"

# Fallback for clients that cannot set headers
curl "https://horses.sportsedgepro.co.uk/api/v1/prices?api_key=sep_live_YOUR_KEY"

Tiers & pricing

The API is sold on its own, independent of any SportsEdgePro dashboard subscription — sign up for a developer account and pick a plan at any time. The same developer login also works for the Greyhound Data API, with an independent plan and keys per product.

Conventions

Response shape

Collections return a data array alongside a meta object.

{
  "data": [ { /* ... */ } ],
  "meta": {
    "count": 100,
    "limit": 100,
    "offset": 0,
    "has_more": true,
    "date_from": "2026-08-01",
    "date_to": "2026-08-07"
  }
}

Dates & paging

• Dates are YYYY-MM-DD; timestamps are ISO 8601.
• Historical endpoints default to the last 7 days if no range is given.
• A single request may span at most 366 days. Walk longer periods with date_from/date_to.
• Page with limit and offset; sort with sort and order.
• List filters are comma-separated, e.g. track=Ascot,Newmarket.

Errors

Errors return a consistent body with a stable machine-readable code.

Horse profiles

Career summary (runs, wins, win percentage, average BSP, back/lay ROI, active dates) and recent form lines. Set runs (1–200, default 20) to control form depth, and optionally country to restrict to one.

Racecards

Races scheduled for a date. Pass date (default today), country (default UK), and include_runners=true to embed declared runners with live prices.

A single racecard with its declared runners. market_id is the Betfair market id from /racecards; pass the same date/country if the race is not today/UK.

Reference

Tracks in the archive with race counts and first/last race dates.

Valid enumerations, sortable fields and archive coverage — useful for validating input client-side.

Usage

Your tier limits, today's consumption and 30 days of history. Does not count against your quota meaningfully — poll it sparingly.
