What is the DiscGolfAPI?

DiscGolfAPI serves structured disc golf course data with no API key. Filtering by country returns each course with its coordinates, region and locality, website, operator and hole count, wrapped in an envelope declaring the licence and attribution requirement.

Disc golf course information has historically lived in one or two proprietary apps with no export path. This API publishes it as structured data instead — every course carrying latitude and longitude, an ISO country and region code, and a stable slug — which is enough to build a map, a route planner or a course finder without scraping anything.

What stands out is the honesty of the envelope. Before the course list you get `license`, `attribution_required`, `terms_url` and an explicit `no_warranty` statement, plus `generated_at` and a `publish_version` telling you exactly which build of the dataset you received. Free data sources rarely bother; here the licensing terms are unambiguous and machine-readable. Do note the attribution requirement is set to true — using this data in public means crediting DiscGolfAPI. Optional fields such as `holes`, `locality` and `operator_name` are frequently null.

Parameters

Parameter	Type	Required	Description
`country`	query	Optional	ISO 3166-1 alpha-2 country code. `GB`
`region`	query	Optional	Region or subdivision code within the country. `ENG`
`limit / offset`	query	Optional	Paging controls for large countries. `50`

Response fields

coursesarray: The matching courses.
courses[].id / slugstring: Stable identifier and URL-friendly slug — `crs_ackers_adventure` and `ackers-adventure` respectively.
courses[].namestring: Course name.
courses[].lat / lonfloat: Coordinates in WGS84, ready to drop onto a map.
courses[].country_code / region_codestring: ISO country code and subdivision code, for example `GB` and `ENG`.
courses[].localitystring: Town or city. Frequently null.
courses[].website / operator_namestring: Course website and operating organisation, where known. Both are often null.
courses[].holesinteger: Hole count, when recorded. Null is common and does not mean the course has no holes.
countinteger: Number of courses matching the filter.
license / license_url / attribution / attribution_required / terms_urlstring / boolean: Machine-readable licensing block. `attribution_required` is true — credit DiscGolfAPI when you publish.
generated_at / meta.publish_version / schema_versionstring: When this build of the dataset was produced, its version stamp and the schema version, so you can detect changes.

Common errors and how to fix them

Null holes, locality or website

These fields are optional and frequently unrecorded.

Fix: Render conditionally. Null means unknown, not zero or absent.

Empty course list

The country has no mapped courses, or the code was wrong.

Fix: Use ISO 3166-1 alpha-2 codes — `GB`, not `UK`. Check `count` before iterating.

Attribution missing from your app

The licence sets `attribution_required` to true.

Fix: Credit DiscGolfAPI visibly wherever you display the data. The terms URL is in every response.

Stale data

The dataset is republished periodically, not updated live.

Fix: Read `generated_at` and `meta.publish_version` to see exactly which build you have.

DiscGolfAPI — frequently asked questions

Is DiscGolfAPI free?

Yes, free to use with no key. The licence does require visible attribution to DiscGolfAPI when you publish the data, and every response restates that in machine-readable form.

How do I filter by country?

Pass an ISO 3166-1 alpha-2 code as the `country` parameter — `GB` for the United Kingdom, not `UK`. A `region` parameter narrows further.

Why are so many fields null?

Hole counts, localities, websites and operator names are optional and depend on what contributors have recorded. Treat null as unknown and render those fields conditionally.

How current is the data?

Every response carries `generated_at` and a `publish_version`, so you can see the exact build you received. The dataset is republished periodically rather than edited live.
