Horse Racing Racecards API

This endpoint returns the daily combined racecard list for the UK and Ireland market, with each race item carrying its nested declared runners. It is a list product, so the unit of retrieval is the race, not the individual runner. That matters when you are designing navigation: users can scroll through meetings and races first, then drill into a selected race or horse using the IDs already present in the feed.

Because the feed is date-aware, it suits a public-facing racecard landing page or editorial calendar where the content changes every day. You can request a specific calendar date in YYYY-MM-DD format, or use the documented tomorrow feed when you want to prebuild the next day’s pages. If there are no races on a non-racing day, an empty list is a valid response and should be handled as normal, not as an error.

A practical implementation is to treat /v1/racecards as the first screen in your race hub. Fetch the current day on load, render meetings and races as collapsible cards, then keep a secondary route or panel ready for a single-race view from the race detail endpoint. That structure gives you a fast overview page while preserving a clean path into richer race-specific content when the user chooses a race.

The list response is also suitable for search and filter controls on your own site. For example, you can offer date selection, a “tomorrow” toggle and pagination without needing to cache and remix unrelated records. Because the returned IDs come from the feed, you should store and pass them through directly when building linked views, rather than matching on names. That keeps your racecard, horse profile and results flows aligned when names repeat or are presented differently.

The endpoint supports a date parameter for a single calendar day and a separate tomorrow option for the documented next-day feed. Those choices are mutually exclusive, so your UI should present them as alternative modes rather than allowing both at once. This is helpful for publishing workflows where you want today’s card by default, tomorrow’s preview in a tab, and a direct link for a specific day from an editorial archive.

Pagination is one-based, and the limit parameter controls how many list items you show per page. Races are the paginated unit; runners inside a race are not separately paginated. That design works well for long cards, because you can keep each race intact with its full declared runner list while stepping through the larger list by page. Beyond the last page, the response becomes empty while meta.total still reflects the total before pagination.

The feed is built to be the starting point for related requests. Each race item exposes the identifiers you need for downstream pages, including race, horse, jockey, trainer and course IDs. Those IDs are the safe way to connect your racecard list with race details, profiles and other linked data. They are not meant to be reconstructed from names, which is especially important where two runners share similar names or where display labels change between views.

A well-structured interface will reuse these IDs throughout the user journey. A meeting page can link each race to the single-race endpoint, runner names can link to horse profiles or horse form, and course references can connect to the racecourse directory or weather. This gives you a coherent site structure without duplicating data logic. It also makes it easier to keep analytics and bookmarking stable, because each page maps back to a consistent feed identity.

The contract is explicit that time, weight and price strings are preserved, not converted. That is useful if your front end needs to present the source wording exactly as received, especially where the feed contains formatting that your users expect to see unchanged. Rather than normalising those fields into your own wording, store and display them as supplied in the response.

This same approach helps keep the racecard faithful across devices. If your product displays runner lines, race timings or prices in compact cards, you can preserve the original string values and manage any layout-specific formatting in your own UI layer. The API is giving you a daily feed of racecard content, not a reinterpreted database record, so your integration should respect the source structure while handling presentation on the client side.

For customer-facing products, the most common build is a daily racecard page with meeting sections, race anchors and a runner list beneath each race. You can add date controls, a tomorrow preview, pagination and race detail links without needing to combine several products just to create the first screen. Because the response already groups runners under each race, the page structure is straightforward for both editorial teams and developers.

For operational or editorial use, the same feed can support daily planning tools, content calendars and internal monitoring of race coverage. A newsroom or trading team can see what is due to go live, then jump into the single-race detail endpoint only where more information is required. That keeps the racecards service focused on discovery, while letting your application decide when to enrich a race with deeper records or related tools.

The racecards endpoint is deliberately not a universal history service. It gives you the daily UK and Ireland race list with declared runners and the IDs needed to continue, but historical depth and completeness are not guaranteed for arbitrary backfilling. If you are building a results archive, a long-form form module or a detailed race card page, you should pair the list with the relevant detail endpoints rather than expecting this feed to supply everything.

That distinction also helps keep your product clear. Use /v1/racecards for discovery, /v1/races/{id} for the selected race, and the horse, jockey, trainer, racecourse, odds or results endpoints only where your interface needs them. The result is a modular integration where each request does one job well, and your front end controls how much detail appears at each step of the user journey.

This endpoint requires an active approved account. Once access is confirmed, you can call the feed from your own server using the API key issued to your account. Keys stay on the customer’s server, which makes it straightforward to protect your integration while still serving public-facing pages. Because the same account also governs request quotas and plan limits, your implementation should watch usage if you expect heavy traffic around major race days.

In practical terms, a good deployment pattern is to fetch the daily list on a schedule, cache it for your own page generation, and refresh when your product needs a current view of the day. If you publish content for both today and tomorrow, keep those requests separate so the right date context is always preserved. That approach matches the endpoint design and keeps your racecard pages predictable for users and editors alike.
